Kaspersky Free Antivirus

“A perfect choice for free antivirus”


Email scanning module | Bootable rescue disk available as a separate download


    • Outstanding malware detection performance
    • Pop-up free hushed detection mode
    • Low Effect on system load


    • Deficiency of dedicated test results to get a free version

Kaspersky Free Antivirus uses the identical detection engine as the business’s well-regarded industrial products, which places it among some of the best acting anti-malware tools around.

On installation, you are asked to agree or opt-out of settings which will automatically delete malicious tools, adware, auto-dialers, and suspicious packages and find other applications which may be used by criminals to damage your computer or information.

You are also motivated to create an account, but you can back out of this as it is not required to use the program. Kaspersky Free supports using a 366-day permit that auto-renews if it runs out.

The desktop closely looks like its aerodynamic counterpart in its clean look and feel, with the main screen that shows your security status and options to scan your system, update its virus database and start added tools. A number of different options are greyed out, prompting you to purchase one of Kaspersky’s paid-for anti-malware suites if you click on them.

Kaspersky Free has a browser plugin to check for malicious hyperlinks on your search results. We were pleased to discover that this doesn’t alter your default homepage or search engine, although by necessity it requires permission to read all of your browser data.

Document, web, instant messaging, network and email scanners are included, but you can not disable or customize any of Kaspersky’s security settings in this free edition. Advanced options enable you to set how paranoid the scanner is, schedule scans and configure the app’s default behavior and which notifications you get.

Sadly, this free version of Kaspersky’s software does not make a regular appearance in the majority of anti-malware testing labs’ results. As a result of this, we have had to rely on performance figures for Kaspersky’s other products using the same engine.

While their functionality should be the same in both real-world and reference tests, the small uncertainty resulting from this extrapolated methodology remains our sole real caveat on what seems to be an ideal choice for free virus protection.

Kaspersky’s engine defended against 100 percent of reference samples and real-world malware exposures across two consecutive months of trials by AV-TEST and in AV-Comparatives’ test. In AV-Comparatives’ real-world malware vulnerability evaluations, it defended against 99 percent of malware without any false positives.

AV-TEST performance data demonstrates that it had a milder impact on site load times than many rivals, especially on a low-power Core i3 system. AV-Comparatives’ tests do not reproduce this, but rather indicate slightly slow first run times for the two program launching and file copying.

But, both found that, overall, its system functionality was at least no more obtrusive than many rivals.
