Pros / Kaspersky scored above average for protection on all supported versions of Windows.

Cons / This program scored lower on performance tests, conducted by independent testers, compared to our top pick.

 Verdict / Kaspersky is a leading program in the antivirus software industry that continually scores high on independent tests for protection and performance, proving it is excellent at detecting and blocking legitimate internet threats.

Editor’s Note: Top Ten Reviews uses test results from the independent laboratory AV-Test as part of our review process for the best antivirus software. AV-Test looks specifically at protection, performance and usability on multiple versions of Windows operating systems, and it performs these evaluations several times throughout the year. We use the most current AV-Test scores available at the time of our review. It is possible that new AV-Test scores will be released after our review goes live on the site. We will consider these scores during our next review of the best antivirus software.

Kaspersky recently released its 2017 version of virus protection software compatible with Windows 10. However, the independent laboratory AV-Test has only conducted tests using its 2016 version. Kaspersky performed so well in those tests and includes so many extra security features that it easily made our list of the best antivirus software and earned our Top Ten Reviews Silver Award.

Test Results

Kaspersky received perfect scores for protection and usability. This means it correctly identified both existing and newly emerging malware threats and blocked them effectively while still allowing good data to pass through. It did dip a little for performance but still remained higher than average: While Kaspersky Anti-Virus may slow down your computer slightly, it may not be enough for you to really tell a difference.

Detection & Removal Tools

Although it is the entry-level Kaspersky security product, Kaspersky Anti-Virus has more features than some others in its product category. In addition to excellent virus protection, Kaspersky includes antiphishing. It scans emails and instant messages to ensure nothing is tacked on that may infect your computer. 

It also automatically scans USB drives for another layer of computer protection. It also has the nifty gaming mode, which ensures the software doesn't interrupt or slow down your games or videos.

 Even if your computer is already infected with a virus, Kaspersky isolates the threat and destroys it. It then automatically recovers your system from any damage it may have received during the threat. A rescue CD is available in the event your computer is so badly infected that it needs to be reset with some assistance.

Kaspersky Antivirus for Windows 8

AV-Test recently released its results for the tests of Windows 8 antivirus software that it conducted in May and June 2016. Kaspersky beat out the competition to become the top-performing computer protection program for Windows 8. It received perfect scores in all three test areas: protection, performance and usability. It is our Top Ten Reviews Gold Award winner for Windows 8 virus protection software.

Kaspersky does its protection work without slowing the PCs it runs on. Moreover, it accurately distinguishes between safe and malicious files. While it is entry-level security software, it has more features than some competing products. For example, some competitors do not warn about phishing sites and cannot automatically detect threats in removable storage media like USB drives. Kaspersky does.

Kaspersky provides real-time protection against malware and secures your online financial transactions. When any PC in the Kaspersky user network bumps into a never-seen-before threat, data about it goes to Kaspersky Lab. The lab then places a threat signature into a cloud database of what's safe and what's dangerous.

Kaspersky Antivirus for Windows 7

Kaspersky beat out the competition to become the Top Ten Reviews Gold Award winner for Windows 7 antivirus protection. In independent tests by AV-Test in February 2016, Kaspersky received a perfect score in protection, performance and usability. Kaspersky scored much higher in each of these areas than the standard Microsoft Security Essentials that comes installed with Windows 7 operating systems, meaning Kaspersky Anti-Virus will protect any gaps in your security that may be there.

Kaspersky Anti-Virus is easy to use, excellent at malware protection and capable of disinfecting PCs that are already infected. It is optimized to take its antivirus information from the cloud, which means it recognizes threats quicker. This also helps keep your virus protection up to date so you are protected from emerging threats. It does this without consuming extensive system resources, so you won't see a decrease in your computer's performance while it is running.

Kaspersky Antivirus for Windows Vista & XP

Kaspersky has consistently offered some of the best antivirus protection. Its protection and usability scores, which determine how well it recognizes legitimate malware threats and blocks them, have always been well over the industry standard. Though AV-Test hasn't evaluated antivirus software on older versions of Windows for several years, Kaspersky has always ranked high as a reliable product for computer protection. Though the newest version has not been tested on these earlier versions of Windows, Kaspersky remains a top solution for Windows Vista antivirus and Windows XP antivirus software.

Help & Support

Kaspersky has some of the best support in the industry. All forms of support – email, telephone and live chat – are available 24/7. This is very helpful, since software issues don't always happen during business hours. Additionally, Kaspersky has forums, how-to videos and FAQs specific to each version of its computer security software and the problems you may experience.


Kaspersky Anti-Virus is among the few very best antiviruses for every Windows operating system. It is excellent at protecting against malware and phishing attacks. If your PC is already riddled with infections, it tracks them down, sets things right and heals the damage. It does not use up valuable computer resources and slow down your system. It doesn't bother you during games and scans all incoming data and files, whether through email, instant messages or USB drives.
