To prevent virus attacks and their consequences, an antivirus program must be constantly running on your PC. Not necessarily paid: there are many free solutions that can provide your personal information with a decent level of protection. This article will help you choose a free antivirus for Windows of any version. The selection of products discussed below was made based on a comparison of their functionality and effectiveness.
Free versions of antiviruses most often feature a single module that provides only basic protection against malware. But there are also those that include a firewall, payment security tool, password keeper, and much more. Perhaps in some ways they are inferior to commercial products of the Internet Security class, but not every home user is ready to shell out $30-80 annually for a license. And this is their main, undoubted advantage.
It represents the most complete set of security modules in one free product. Its package includes:
- A proactive anti-virus protection tool that prevents infections by all types of malware in real time.
- Anti-virus scanner to find and eliminate active infections. Launches according to a schedule and upon user request.
- An intrusion prevention system (HIPS) based on behavioral analysis of Windows programs and components.
- A two-way firewall is a means of protection against incoming and outgoing threats.
- Content filter is an add-on firewall module that allows you to create custom rules for accessing the content of various web resources.
- Comodo Secure DNS - the ability to configure a network connection through Comodo's secure DNS servers.
- Viruscope is an intelligent analyzer of the activity of running processes.
- Comodo Rescue Disk is a wizard for creating a bootable disk (flash drive) with an antivirus to treat locked and unbootable systems.
- Comodo Dragon secure web browser.
- Secure Shopping is a system for secure online shopping, banking and protection of payments made online.
- Internet Security Essentials is a tool for checking the validity of SSL certificates. Protects against theft of user data through phishing (fake) web pages.
- Virtual desktop.
Perhaps, looking at the impressive list of Comodo Internet Security features, you thought that the application would slow down your computer. But no: its system requirements are quite low, so it is suitable for laptops that work offline and for weak machines.
The antivirus provides equally good protection for both old Windows XP and modern Windows 10. Its virus databases and software components are regularly updated. By the way, the Comodo Internet Security license agreement gives the right to use it not only at home for personal needs, but also in commercial organizations.
FortiClient Endpoint Security (Standard)
Until 2011, it was a business product for corporate users, but after Fortinet switched to developing other lines of antiviruses, its license became free for everyone. Support for the application has now been completed, but virus database updates are released as before - once a day.
Since the FortiClient Endpoint Security software has not been updated for several years, no one guarantees its correct operation on Windows 8 and 10. However, on older operating systems such as XP and Seven, no failures were observed.
The application includes modules:
- Antivirus + Antispyware (real-time protection).
- Mail traffic checking tool.
- Anti-virus scanner with the ability to run according to a schedule and user request.
- Personal firewall.
- Content filter.
- Spam blocking module.
- Logging and reporting system (to track prevented threats and the operation of the program as a whole).
- VPN client for secure access to corporate (and other) networks. Installed separately at the user's request.
FortiClient Endpoint Security antivirus is very undemanding in terms of hardware resources - it can even run on computers with 128 Mb of RAM running Windows 2000.
- a slightly more modest solution than the previous 2. This is an antivirus with a basic set of functions and a two-way firewall attached to it. However, small functionality does not mean that the application is weak or ineffective. The ZoneAlarm Free Antivirus+ antivirus engine was developed by one of the market leaders in information security products - Kaspersky Lab, which in itself promises quality.
What exactly is included in ZoneAlarm Free Antivirus+:
- Real-time anti-virus monitor.
- Anti-spy.
- A scanner to check your hard drive and removable media for infection.
- Behavioral analyzer - monitors the behavior of programs and operating system components. If there is a threat, it blocks the process.
- Protector of user personal data.
- A tool for checking downloaded files for content safety.
- Online data backup tool. Users of the free version have 5 GB of disk space available.
- Firewall for safe Internet surfing.
The free version of ZoneAlarm Free Antivirus+ is available for home, non-commercial use only.
The antivirus supports all versions of Windows, from XP to Windows 10, but its system requirements are quite high. In particular, it needs a processor with a frequency of 2 GHz and 2 GB of RAM, but, according to user reviews, this is not enough. The program is not suitable for weak computers.
The best basic antiviruses
The following rating is based on the results of comparative tests conducted in 2016 by independent test laboratories AV-Test and AV-Comparatives. 4 products were named the best free antiviruses for Windows.
This antivirus is good not only for its high level of threat detection and the absence of false positives, but also for its convenient, well-thought-out interface, as well as flexible settings. It is capable of providing basic protection to PCs running any version of Windows, starting with XP.
Product functionality:
- Anti-virus monitoring using several detection technologies: signature (based on comparison of suspicious samples with data from virus databases), polymorphic (a special method for recognizing “mutating” viruses), behavioral, heuristic (identifies new, previously unknown types of threats based on behavioral and other signs ).
- Antivirus scanner.
- The CyberCapture system is a cloud-based technology for preventing infection by unknown malware. The method is based on isolating a suspicious file and then analyzing it in the cloud.
- The web protection and email control module provides security checks for emails, links, email attachments, and downloaded files.
- a lightweight antivirus that hardly loads system resources. Suitable for weak and outdated computers.
The second leader of our top is the well-known and beloved Avast. In addition to the fact that this antivirus successfully copes with all types of threats, its free version includes many useful add-ons.
Components:

- Integration with MyAvast account. Thanks to it, you can centrally control your devices running Avast antivirus.
Avast Free Antivirus is officially certified for Windows 10, but can also be used on Windpws 7, 8, XP. Suitable for weak computers.
Avira has often occupied the highest positions in ratings in recent years. You can personally verify the quality and reliability of this vendor’s products by installing a free solution on your computer—a solution with a somewhat non-standard and interesting set of functions.
What Avira Free Antivirus includes:
- Cloud antivirus monitor using proprietary Avira Protection Cloud protection technologies.

The best free antivirus scanners
If a standard antivirus does not protect the system from infection (or until now it simply did not exist), most users try to first launch an antivirus scanner, “sharpened” to search for and eliminate the activity of malware. They usually choose the most popular ones, but, unfortunately, they do not always bring results.
The independent Polish laboratory AVLab tried to find out which disposable anti-virus scanner is better and more effective than others. The study was conducted on virtual machines running Windows 10 under conditions close to real ones. All presented scanner samples were tested against the same types of threats, of which there were more than 7,000. The best results—successful recognition and neutralization of more than 99% of malicious objects—were again shown by 4 products.
- a scanner with two anti-virus engines developed by Bitdefender (one of the recognized leaders in the information security products market) and Emsisoft themselves. It works without installation on your computer - just download and run. It does not conflict with antiviruses that are standardly installed on the system, and can run under any version of Windows. Undemanding on PC hardware resources. It does not significantly affect the power consumption of the device, so it can be used on laptops and Windows tablets that work offline. Has a Russian-language interface.
is an application with advanced cloud scanning technology that allows you to quickly and effectively eliminate any threats. Including complex and hidden ones (rootkits), which are often missed by other antivirus scanners. It has several scan profiles: quick (only critical areas of Windows), full (all drives) and custom (individual drives and folders).
The product is available in versions for 32- and 64-bit systems. Supports all editions of Windows. Does not conflict with standard antiviruses. The interface is only in English.
It is also built on the basis of two antivirus engines - Bitdefender and Arcabit. Uses cloud technologies to detect malicious objects, but is no less effective even in the absence of Internet access. Interface in English and Polish.
— to recognize malware, it uses NOD32 virus databases and the proprietary ThreatSense heuristic system, thanks to which it easily identifies even complex and unknown threats. Contains a minimum of settings and can be launched with one click. Has an archive checking function. The interface has been translated into Russian.
Malicious programs in the context of the current article (PUP, AdWare and Malware) are not quite viruses, but programs that exhibit unwanted activity on the computer (advertising windows, incomprehensible behavior of the computer and browser, Internet sites), often installed without the knowledge of users and difficult to remove. Special malware removal tools for Windows 10, 8 and Windows 7 allow you to deal with such software automatically.
The biggest problem associated with unwanted programs is that antiviruses often do not report them, the second problem is that the usual removal paths for them may not work, and the search is difficult. Previously, the issue of malware was addressed in instructions on how to . This review contains a set of the best free utilities for removing unwanted (PUP, PUA) and malware, cleaning browsers from AdWare and related tasks. May also be useful: , .
Note: For those who have encountered pop-up ads in the browser (and their appearance in places where they should not be), I recommend, in addition to using the indicated tools, to disable extensions in the browser from the very beginning (even those that you trust 100 percent) and check result. And only then try the malware removal programs described below.
Microsoft Malicious Software Removal Tool
If Windows 10 is installed on your computer, then the system already has a built-in malware removal tool (Microsoft Malicious Software Removal Tool), which works both automatically and can be launched manually.
You can find this utility in C:\Windows\System32\MRT.exe. I should immediately note that this tool is not as effective as third-party programs for combating Malware and Adware (for example, AdwCleaner, discussed below, works better), but it’s worth a try.
The entire process of searching for and removing malware is performed in a simple wizard in Russian (where you just need to click “Next”), and the scanning itself takes a long time, so be prepared.
The advantage of the Microsoft Malicious Software Removal Tool MRT.exe is that, being a system program, it is unlikely to damage anything on your system (subject to its licensing). You can also download this tool separately for Windows 10, 8 and Windows 7 on the official website
Finding out what the best malware removal tools are is not that difficult. Upon request, you can easily find applications on the Internet that allow you to troubleshoot computer problems associated with virus infection.
Such software is usually distributed free of charge or shareware.
Although its capabilities include a quick search and guaranteed removal of malicious code and annoying advertising, which well-known (and, most often, paid) antiviruses cannot always cope with.
Built-in Windows 10 tool
The first way to get rid of malicious applications, which the average Windows 10 user should use, involves launching the already built-in Microsoft Malicious Software Removal Tool.
Sometimes it works automatically, but if a virus infection has already occurred, the tool is launched manually. You can find MMSRT in the System32 folder of the system disk, located in the System32 directory. The efficiency of the application is not very high, but at least half of the problems will be solved.
Rice. 1. Windows 10 Malicious Software Removal Tool.
The benefits of using the product include:
- Russian-language interface;
- intuitive controls;
- no need to download additional software.
The application's disadvantages include long scanning times and low efficiency. And you can download it not only for Windows 10, but also for the 7th and 8th versions of the operating system. The update, numbered KB890830, is only 52.8 MB in size.
Fast and free AdwCleaner
One of the most famous and effective programs for removing unwanted applications from your computer is AdwCleaner. The advantages of using it include working in Russian, no need for installation on a computer, and constantly updated updates that improve the quality of system testing.
In addition, after completing the scan, AdwCleaner gives the user several recommendations on how to prevent infection with malicious code. And to launch the utility, you just need to click the start scan button, and, after reviewing the results, set the settings and select the information to be deleted.
Rice. 2. Search for malicious code using the AdwCleaner utility.
A peculiarity of the application is that during the scanning process it sometimes becomes necessary to restart the computer. And after completing the work, a report is displayed on the screen, which can be saved as a text file.
Assistant in the fight against extensions Malwarebytes Anti-Malware Free
Rice. 3. Malwarebytes Anti-Malware main window
Simple yet effective Junkware Removal Tool
Rice. 4. Report on the operation of the Junkware Removal Tool utility.
The utility is accompanied by the creation of a system restore point. And during the scanning process, problems are automatically corrected and virus programs are removed. The check ends with the creation of a detailed report on the problems found and their solutions.
CrowdIsnpect – search for unwanted processes in the system
Malicious applications can also be detected by processes running on the system. This is the basis of the operating principle of the CrowdInspect utility, which during its operation scans the startup list and currently running services. Using a constantly updated database of viruses and unwanted software, the program collects information about processes and compares it with a list of potential threats.
Rice. 5. Analysis of Windows processes using the CrowdInspect utility.
One of the results of checking the CrowdInspect system is to display a list of network connections and IP addresses, as well as the reputation of the sites to which they belong. Although only advanced users can understand most of this information. For others, it is advisable to choose utilities that automatically fix problems to remove malicious code.
Shareware utility Zemana AntiMalware
In terms of effectiveness in combating viruses and unwanted extensions, the Zemana AntiMalware application is not inferior not only to other free utilities, but even to paid versions of some well-known antiviruses. The advantages of the program include the possibility of cloud search, a clear Russian-language interface and real-time system protection. The paid Premium version has even more advantages.
Rice. 6. Search for malware using the Zemana AntiMalware utility.
Zemana does a good job of removing plugins in browsers, the presence of which often leads to pop-up advertising messages. Although to start searching for extensions, you will have to change the program settings by going to the “Advanced” section.
And the disadvantages of the utility include conditionally free distribution - after 15 days you will have to pay for its use. Although usually a few hours are enough for a user to quickly scan a computer, after which the application is removed.
HitmanPro - maximum efficiency when removing plugins
Rice. 7. Operation of the HitmanPro utility.
The program effectively removes most common viruses. And when checking browsers, it finds and fixes problems with third-party extensions. After the scan is completed, the user is prompted to review the list of detected problems. And, if any of the marked files is not dangerous, in the user’s opinion, it can be removed from quarantine.
Spybot Search & Destroy – increasing PC security
Rice. 8. Spybot Search & Destroy – search, fix and prevent problems.
Spybot is able to monitor changes to the registry and system information, thanks to which it not only solves existing problems, but also ensures the prevention of possible problems. In addition, all changes made by the utility can be undone - sometimes this helps to avoid Windows malfunctions when a useful file is deleted along with the virus.
The most powerful but slow Dr.Web CureIt!
The most powerful and effective utility can be called Dr.Web CureIt! , the advantages of which include the possibility of free use. By downloading the latest version of the application (the size of which exceeds 100 MB) and running it on your computer, in a few hours you can receive a report on the work done and a system that is 99.9% free of viruses.
It is CureIt that recommends using the technical support of some Internet providers. The application has only one drawback - you can use it only once. A few hours after downloading, the next update comes out, and the old one stops working.
The advantages of the utility include not only a high level of efficiency in detecting malware, but also the ability to download it again. After downloading again from the manufacturer’s official website, the application is again ready to detect viruses. At the same time, the databases are already updated, and the search efficiency increases.
Rice. 9. Message about the need to update the Curelt utility.
Solving problems with browsers
When removing viruses, you should also pay attention to browser shortcuts - often they are the source of the problem. The malicious code is written into the shortcut properties and changes the launch method:
- sometimes when entering the Internet, the user ends up not on the main page, but on another site - most often a phishing site or advertising some services;
- When the browser is launched, a third-party plugin may be installed that changes the search engine, home page, and network settings.
You can solve the problem manually by checking your browser shortcuts. But the best way to do this is with utilities such as Shortcut Scanner. The free application checks logical and external drives for unwanted programs, identifying suspicious or broken shortcuts.
The advantage of using this tool is that it is free to distribute and works on any modern Windows system (from XP to 10); the disadvantage is the lack of a Russian-language version.
If an unwanted plugin has already been automatically installed in the browser, you can remove it through the extensions menu in the settings. Otherwise, instead of going to the selected pages, advertisements and extraneous resources will appear on the screen.
Most often, this problem occurs among users who have already installed a significant number of extensions and do not notice 1-2 extra ones. If there are practically no plugins, it is easier to notice a new one and take measures to disable it. And if you are not sure that the add-on is actually malicious, special utilities designed for specific browsers will help.
For Google Chrome, the official developers have created a utility called the Cleaning Tool. It automatically checks for embedded malicious code every time you launch your browser.
If a problem is detected, the plugin is disabled along with other extensions. After this, the user can restore the add-ons he needs manually.
Rice. 11. Search for malicious code using the Chrome Cleanup Tool.
For Mozilla Firefox and the standard Internet Explorer browser for older versions of Windows, there is a free application Avast Browser Cleanup.
The utility automatically scans two browsers (if they are present in the system), and as a result produces a list of suspicious plugins. The antivirus program can be downloaded from the manufacturer's official website.

Other companies also produce similar functional and free utilities. Moreover, for different browsers and with a wide range of capabilities. Some programs also provide effective real-time protection - however, most of them have a paid feature for this.
conclusions
Using applications that remove unwanted software does not eliminate the need to install antivirus software. Each program performs its own tasks. Antivirus utilities protect the system almost constantly and prevent infection of system files.
And applications to fix existing problems are needed mainly after the antivirus has proven ineffective. Using two options at once - installed and periodically launched utilities - will ensure maximum protection efficiency. Although in order for the computer to be even more secure, it is advisable:
- follow the recommendations of anti-virus utilities that issue warnings when entering suspicious resources;
- use an antivirus to check files downloaded or recorded from an external storage device, the origin of which is unknown (for example, downloaded not from the official website, but from a third-party web page);
- Set your antivirus settings to automatically update virus databases and run the application manually at least once a week.
Preventing your computer from becoming infected with viruses and other types of malicious code will reduce the likelihood of problems occurring. Although neither Curelt! nor even a paid antivirus provide 100% protection.
Best Malware Removal Tools
It’s worth starting with the fact that malicious programs in this context (Malware) are not quite viruses; rather, they are programs that exhibit unwanted activity on the computer, are installed without the knowledge of users and, on top of everything else, are difficult to remove.
Cleaning Windows from spyware, malware and files
In this video, I will tell you how to clean your computer on the Windows operating system from spyware and malware and files, as well as how to free up space on your hard drive from temporary files and how to clear the cache. Three free utilities will be reviewed
The development of virus software occurs at such a pace that not all antiviruses can cope with it. Therefore, when a user begins to suspect that malware has appeared on his computer, but the installed anti-virus program does not find anything, portable scanners come to the rescue. They do not require installation, so they do not conflict with the installed protection.
There are many scanners that can easily determine if there is a threat on your system, and some will even clean it of unnecessary files. You just need to download the utility you like, configure or download the databases if necessary, run it and wait for the result. If problems are found, the scanner will offer you a solution.
Users also use anti-virus utilities when there is no protection on their computer, because it is easier to use a scanner than to forever load the processor with an anti-virus program, especially on weak devices. Also, portable utilities are convenient, because if you have problems with the installed protection, you can always run a scan and get the result.
Method 1: Dr.Web CureIt
Dr.Web CureIt is a free utility from the famous Russian company Dr.Web. This tool is capable of treating detected threats or quarantining them.
Method 2: Kaspersky Virus Removal Tool
Kaspersky Virus Removal Tool is a useful and accessible tool for everyone. Of course, it does not provide such protection as Kaspersky Anti-Virus, but it copes well with all kinds of malware that it finds.
Method 3: AdwCleaner
AdwCleaner is a lightweight utility that can clean your computer of unwanted plugins, extensions, viruses and more. Can fully check all sections. Free and does not require installation.
Method 4: AVZ
AVZ's portable mode can be a very useful tool for removing viruses. In addition to cleaning from malicious programs, AVZ has several useful functions for convenient work with the system.
Knowing several useful portable scanners, you can always check your computer for virus activity and eliminate it. In addition, some utilities have other useful functions that can always come in handy.
If you are tired of installing and uninstalling antiviruses, downloading antivirus databases and activating keys, turn to online antiviruses. Checking files for viruses without installation is a completely worthy alternative to traditional scanners.
We have selected half a dozen reliable, free and effective anti-virus scanners that work online - that is, through a browser. This way you can find out if there is a virus on your phone without downloading third-party programs.
Which web service should you choose for a one-time check? Is online antivirus suitable for Android? Read about all this in our review.
List of online antiviruses:
ESET Online Scanner - online file scan for viruses
ESET's antivirus scanning service is a comprehensive and effective antivirus. It works from a browser, scanning files and does not require installation on a computer.
How to check a file for viruses in ESET Online, video instructions:
Unlike the desktop version of ESET Nod, this web antivirus is free to use. Don't think that it makes no sense to require a full-fledged scanner from a web application. According to the creators, the online antivirus successfully copes with Trojans, the latest viruses, worms, and phishing threats.
The user can select files on the computer disk to scan, specify memory areas, etc. Moreover, to run an online check, you do not need to have administrator rights.
At the end of the search, ESET Online Scanner offers to remove the found viruses or quarantine infected files.
In general, cleaning viruses using ESET Online Scanner web antivirus makes sense in many cases. In particular, if you want to scan someone else’s computer, check a flash drive for malicious files online, but you do not have the rights (or desire) to install applications.
Powerful online scanner Doctor Web
Doctor Web Online scans files on websitesThis service is designed to check security links. You paste a link to a suspicious site into a special text field, and Doctor Web scans the attached files on the html page, examining whether there is malicious code. As a rule, a virus threat on online resources is hidden in javascript files. If scripts are contained in the database of malicious sites or the site redirects to another resource, Doctor Web Online will notify you about this.
As you can see, the service is very minimalistic, there is only a web-based antivirus shell, which is not very convenient. It would be good if the Doctor Web service acquired, say, an Android application for online checking or, ideally, a browser add-on. At this time, we would not recommend the online version of antivirus for use on a phone.
Tip of the day. By the way, if you need a good free antivirus to scan your computer (or memory card/flash drive) for viruses, without downloading additional applications, we recommend downloading the Doctor Web healing utility. It uses the current databases of the desktop version of Doctor Web, while the functional part is reduced to a minimum.
VirusTotal - total online scanning of files for viruses
Online scanner VirusTotalVirusTotal is another free service that checks for viruses online. It scans the contents of files and code of sites on the Internet. VirusTotal scans any suspicious content for worms, malware, Trojans and other types of pests and viral threats, and will help check Android for viruses.
Video on how to use the service:
VirusTotal also allows you to search for threats in comments that users post on files and URLs, check passive DNS data, and retrieve threat information related to domains and IP addresses.
VirusTotal stores all analyzes in its database. This allows users to search for reports with MD5, SHA1, SHA256 data. Search results return the last crawl performed on the resource you are interested in.
Kaspersky Online Scanner (VirusDesk)
Kaspersky web scannerOnline service from the creators of Kaspersky Anti-Virus for Android. Checks files and links on the Internet and does not require the installation of additional modules. When you download a file, Kaspersky scans it across its databases for existing threats and displays the result. In this case, md5, SHA1 and SHA256 hashes are checked. All databases are regularly updated, as evidenced by the corresponding inscription above the file upload field.
The result of the scan may be negative, in which case VirusDesk issues a status: the file is infected or suspicious.
Important! Unlike conventional antiviruses, you can only scan a file for viruses, and you cannot quarantine or automatically delete it - this can only be done manually.
This online antivirus is also suitable for checking your phone for viruses. You can upload files up to 50 MB; batch mode is not supported. The scanner does not remove viruses - the user must perform this action independently. At the same time, to perform a single scan, Kaspersky VirusDesk can become such a one-time antivirus, which is also not bad.
Video instruction:
VirSCAN - online antivirus for Android
Online antivirus VirSCAN.orgUsing the VirSCAN.org service, it is possible to check Android for viruses online, as well as online scanning of files for malicious code.
For example, you can send apk applications or other files for verification (the size should not exceed 20 MB). These can be zip and rar archives or password protected (only the passwords “infected” and “virus” can be set).
The main and most significant feature of the VirSCAN online antivirus is a huge database of regularly updated scanners, including kaspersky, avg, drweb, symantec and others. Among other things, VirSCAN checks MD5 and SHA1 hashes against its databases.
The downside of this online checking mechanism is the slow speed of operation, the absence of any settings (that would speed up the process) and the lack of scanning options: only downloading single files to scan for viruses is allowed.
AVC UnDroid – service for checking apk files
The free online service AVC UnDroid is designed to search for viruses in the contents of apk files. It uses scanning engines such as Buster Sandbox Analyzer, ssdeep and APKTool.
To check an apk for viruses, click the Select APK... button and download the installer file to check on your phone. AVC UnDroid supports data up to 7 MB in size, which is enough for most tasks.
Uploaded files are analyzed inside AVC UnDroid, after which the user receives a detailed scan report - file hashes, security rating and additional information.
Other data types are not supported and you can only upload one file at a time.
For convenience, you can register. This opens up access to statistics and comments, increases the limit on downloaded files and increases priority.
As stated in the terms of use, this online verification service is experimental. Downloaded apk files and their contents can be used by the service, and there is nothing wrong with that.
Conclusion. This article lists a small part of online services for checking files over the Internet. If this is not enough, we advise you to study our guide on how to check your phone for viruses. Do you know other methods and services that will help detect infected code online? Share via the feedback form, we will be grateful!
