Richtechy analyzes the best free antivirus for windows 10, currently available. The usability and effectiveness of each item on this list have been carefully examined. If you plan on surfing the internet, installing an antivirus software on your computer is essential, mainly due to the proliferation of iframes containing infected advertisements, spam full of malware and drive-by downloads that infest even the most legal, honest and popular of sites.

To evaluate the performance of each antivirus, our reviews have put together the data collected by AV-TEST and AV-Comparatives, two authoritative testing labs that deal with malware and security. In addition to analyzing the data collected by these two prestigious laboratories, we have also tested each antivirus in person to evaluate the user experience and the type of functionality it offers. Although, all the antivirus software we have reviewed, have done a good job of protecting us against malware, Kaspersky Free Antivirus 19 has the most efficient malware detection engines that we have seen in a free product.

This software also has minimal impact on system performance. With that said, we present to you the best free antivirus for windows 10 to help keep your personal computer safe.

Email scan form An executable rescue disk from external media is available as a separate download. Kaspersky Free Antivirus uses the same detection engine as the excellent commercial products offered by the same manufacturer, which certainly makes it one of the best malware tools currently available.

During installation, you will be asked if you want to use the recommended configuration that will automatically eliminate malicious files, adware, auto-dialers, suspicious software and those that could be exploited by criminals to damage your computer or your data. You can change these settings at any time. You will also be suggested to create an account, but since it is not necessary to have a profile to use this software, you can avoid doing so. Kaspersky Free is installed with a day license that automatically renews itself upon expiration.

With its simple and clean interface, the Kaspersky Free Antivirus client resembles its paid counterpart very much. The main screen shows the status of your protection and options for scanning your system and updating the virus database, as well as various other additional tools.

Some options are disabled, and by clicking on it you will be asked to purchase one of the paid Kaspersky anti-malware suites. Kaspersky Free also includes a plugin that will allow you to check if there are dangerous links in the results of your searches.

We were pleased to find that this plugin does not change your default homepage or search engine, even if it needs permission to read all your browser data. The advanced settings will allow you to schedule the scans and define what their sensitivity will be, the default behavior of the program and what kind of notifications to receive. Unfortunately, the free version of the Kaspersky software does not appear in most of the test results of the anti-malware labs, which is why we had to rely on the performance statistics of the other Kaspersky products that use the same detection engine.

Even if the performance of the free and paid antivirus should be the same both in the tests carried out in the real world and in those with the reference samples, the slight uncertainty due to the fact of having to use this type of method remains the only thing reserved against what seems to be truly the perfect free antivirus. The performance data provided by AV-TEST show that this antivirus has had a much more incisive impact on the loading time of websites than that of most competing software, especially on a low-consumption Core i3 system.

The AV-Comparatives tests did not give the same result, and instead indicate slowdowns in the times of the first start of the applications and in those of copying the files.

Tests from both labs, however, observed that the impact of Kaspersky Free on system performance was less conspicuous, or at least on the same level, than that of most competing software. The built-in protection by default in Windows systems is excellent and certainly one of the best free antivirus for windows. Windows Defender, the virus protection built into Windows systems from 7 onwards, has improved over the years, and has achieved excellent performance in the most recent tests carried out by various independent bodies.

Its impact on system performance is not excessive, and is practically unnoticeable on most PCs. In fact, Windows Defender slows down the loading of web pages much less than most competing software. However, using Windows Defender rather than third party software may not provide you with any performance improvements.

The performance tests of this software by AV-Comparatives have revealed that any other antrivirus has a lesser impact on the overall system performance than Windows Defender, which slows down the copying of files and installation operations in particular. The tests performed by AV-TEST confirmed the slowdown of the installations, even if this laboratory has had less problems with copying the files.

The interface and functions of Windows Defender vary according to the version of the system on which it is installed. The Windows 10 Security feature opens on a screen that gives you an overview of your protection status, including the dates when the software was last updated or scanned for malware.

Each function has a page dedicated to it. Protection from viruses and other threats is entrusted to fast, complete or customized scans, and it is also possible to perform an intensive scan in offline mode suitable to face the threats more difficult to remove.

You can manually update virus definitions and enable or disable options such as cloud and real-time protection: using the latter is not really a good idea. In the firewall tab you can open ports, configure notifications and define specific settings for private and public networks. This page offers the possibility to manage the profiles of minors who use WIndows devices, allowing you to activate filters for web content, controls on the apps that are installed and the time spent in front of the screen.

Ransomware protection and file recovery are new features that store backup files on Microsoft OneDrive, although by default you will only have 5 gigs of space available.

Although Windows Defender has not always had the best performance over the years, the results of the last few tests have been excellent. In the results of the most recent tests performed by AV-TEST, Windows Defender managed to protect the system from all the malware contained in the reference samples, and from almost all the infected files to which the system was exposed in the real world during a period of two months of testing, reaching a percentage of The free Bitdefender antivirus suite does not have the same number of features offered by paid counterparties, but uses the same detection engine.

Unfortunately, just as in Kaspersky and Avira, the free version of Bitdefender has not been the subject of many tests, which means that we had to rely on the results of the other Bitdefender products that uses the same malware detection engine. After installation, a process which also includes a scan of the threats already present on your system, you will be asked to create a Bitdefender account.

A simple window shows you if your protection is up to date or not, and a button to start the system scan.

There is also a box where you can drag files and folders to perform an instant check, which is ideal when you come across an unknown file. Through your Bitdefender account, you can check some basic information about the protection status of your computer, and know what threats the software has protected you from recently. Bitdefender has successfully defended the system in all the latest tests carried out by AV-Comparatives on real-world threats. The incidence of false positives has always remained low, and compared to competing software Bitdefender has had a very discrete impact on the system performance both in the AV-Comparatives and in the AV-TEST tests, especially when it comes to loading websites and file downloads.

Bitdefender Antivirus Free Edition seems to be a great choice for anyone looking for an easy-to-use and effective protection tool. Avira Free Antivirus is an essential and simple to use software, although we were surprised by the relatively high impact revealed in the last performance tests carried out by AV-Comparatives, which highlighted significant slowdowns in the time of downloading files from the web.

The main application, however, is well-designed. Avira has chosen not to fill its client with functions, but instead to present a series of optional extras that you can choose to add both during installation and after, and which include a tool for scanning networks, a MB VPN service free and other tools for system optimization. The Avira interface is essential and very compact. It opens with a page showing the status of your protection, which modules are active and some advertisements for Avira paid products.

Since this is the free version of Avira, some modules are only available for Pro users. You can use the module for real-time protection, but not the tools dedicated to web and email security, which are only available in the Pro version. Its firewall settings plug directly into the Windows firewall, and are pleasantly easy to use. You will be able to perform complete, customized and predefined scans on active processes, on local and removable media.

Avira Antivirus Free uses the same detection engine as the paid counterparts, to which we had to refer for the test results. A more thorough test for false alarms found only four errors, which is definitely a good result. It shares the same detection engine as AVG, which Avast purchased in However, the two clients are not the same, and during the tests we observed small differences in performance, which generally depend on the type of interaction required by the user when a threat is detected.

In the case of Avast, it is very important to choose to change the settings during the installation and configuration of the software. The default installation settings also include Online Security, a very useful browser plugin that scans websites for malware and blocks ad trackers, and an integrated password management tool, although we recommend that you use a dedicated program.

The software has a simple interface that follows the Modern UI style of Windows 10, with a main screen showing the status of your protection and has a button for intelligent scanning. You can perform different types of complete and partial scans; view which viruses have been previously detected; enable or disable the automatic scan of Avast files, web and emails; as well as look for potential vulnerabilities on your network, and create a rescue disk in case malware prevents your system from booting properly.

The program also has a free license that is automatically renewed, and which you can link to an Avast account. The client displays not too intrusive advertisements and buttons for extra functions that advertise paid products, which among other things include a firewall, a data shredder and a utility for cleaning the system.

Avast advanced settings allow you to add URLs not to be scanned, or to scan those URLs that could include unwanted but not harmful programs, you can also disable audio warnings and activate the super paranoid Hardened mode. Together with AVG, Avast is one of the antiviruses with the lowest impact on performance currently available.

Although installing it might be a little annoying because of the potentially unwanted extensions selected by default, Avast is certainly well equipped to defend your PC against various threats, despite there being some small problems with ease of use. AVG was purchased by Avast in , and both use the same virus database and the same detection engine. This is mainly reflected in the very similar performance of the two software during the tests, even small differences in their behavior can be observed, especially when user interaction is required, which can make a big difference.

The performances of AVG and Avast in the most recent tests have been practically identical, even if AVG lacks some additional functions, such as an integrated tool for creating rescue disks.

The AVG rescue disk, which is used in the event that the malware present in the system makes it impossible to start your PC, must be downloaded separately. If you are satisfied with the security offered by your current browser, you can also decide not to install AVG Secure Browser. If you choose to install it, be aware that it will become your default browser and that it will open automatically when you log in to your PC. AVG Free offers real-time protection and the ability to perform scheduled and on-demand scans, but the client also shows which paid features you are missing, such as a firewall and tools for encryption and against phishing.

If you wish, you can also associate AVG with an online account and add some extra paid features, including a VPN and a password management tool. Additional settings and options are available in the menu on the top right of the client, including access to quarantined files and a file shredder, a tool that will allow you to permanently delete files from your PC.

You can also uninstall each of the individual components, although we do not recommend that you do so. To evaluate the performance of this antivirus, we considered the results of tests carried out by the most important laboratories on other AVG products that use the same detection engine.

It must be said that in the AV-Comparatives tests dedicated to false positives, AVG mistakenly identified 15 non-infected programs as malware. Like Avast, AVG has minimal impact on the performance of most systems. However, we would prefer that both Avast and AVG avoid automatically installing potentially unwanted browser extensions such as SafePrice. The key element of each antivirus is its detection engine, which establishes the potential danger of a software based on the databases containing the virus signatures, and on the heuristic analysis of their characteristics and their behavior.

Detection engines are the core of any company that creates antivirus programs, and typically the products that a developer offers for free are equipped with the same engines used by the paid counterparts.

Paid products justify their price with extra features, such as firewalls and tools for system optimization. Modern antivirus software constantly checks your PC, and scans programs, files and sites in real time for potential threats.

To make you feel even more relaxed, they also offer you the option of performing manual or scheduled scans. By default, most antiviruses perform an optimized scan that checks the files that are most likely to have been compromised. In determining the best free antivirus for windows 10, we used data on detection engines, not data based on a specific product.

For example, we used the results of Kaspersky Internet Security to draw conclusions about Kaspersky Free, which also uses the same engine. The data we considered was collected between January and May , using the latest versions of the tested antivirus software. AV-TEST conducts both real-world tests, during which the systems are exposed to contaminated sites and emails, and tests based on reference samples, during which several thousand infected files collected in the four weeks are introduced into the systems previous.

AV-Comparatives also conducts a wide range of tests. The AV-Comparatives data we used in our review are those obtained from tests carried out in the real world during which systems are exposed to sites infected by drive-by downloads , and those on false positives and system performance.
