Everything good about Kaspersky Anti-Virus

Kaspersky Anti-Virus is super easy to install and while every computer protection solution requires some setup, Kaspersky is as close to plug-and-play and you'll get. Most everything you need is already enabled, so you're computer is monitored for internet threats from the get-go. You do need to enable the browser extension to help Kaspersky stop threats from downloading from the internet and to help warn you of phishing schemes while you browse.

When we tested this antivirus software, we attempted to download over 300 hundred malicious files and connect to malware-riddled websites and phishing schemes. Kaspersky stopped 98 percent of these threats. Each malware file we tried to download, Kaspersky would interrupt and display two warning messages, one in the browser itself and another popup message. Kaspersky left little doubt that what we were attempting to access was dangerous. And when we used search engines, search results were listed with a noticeable green or red Kaspersky icon next to each one so we could easily tell if a website was safe to visit or not.

Kaspersky clearly marks dangerous websites in search results and displays warning messages when malware is attempting to download to your computer.

We did purposefully allow a few threats through so we could try out Kaspersky's virus scan capabilities. It didn't have any trouble finding the Trojans, viruses, and rootkits. Threats were typically scrubbed completely from our computer, though a few were sent to the Kaspersky quarantine folder for us to inspect closer before being permanently removed.

For even more protection, Kaspersky Anti-Virus includes a virtual keyboard that opens in your browser screen. You can use this to enter user names and passwords so they are hidden from internet snoops and can't be captured by keyloggers. As an added bonus, Kaspersky is a decent value, too. You get a minimum of three user licenses to protect several Windows computers at the same time.

And the not-so-good

There has been a lot of accusations of Kaspersky using its internet security programs to gather classified information about the United States and sending it to Russia's government. Kaspersky consistently denies these reports while the U.S. government has ordered every government agency and worker to stop using these programs, even for personal use, as a precaution. Recently Kaspersky has made strides to help show its dedication to security and privacy by moving its headquarters and center of operations to Switzerland.

As part of our testing, we did look at how much drag running Kaspersky caused on our computers. We didn't notice too much slowdown performing normal tasks like searching the internet, playing online games or watching YouTube videos. We did notice that during deep virus scans that Kaspersky did cause files we were uploading or downloading to take a little extra time to complete. But overall it wasn't enough to frustrate us.

Is Kaspersky Anti-Virus for you?

We highly recommend Kaspersky Anti-Virus as a basic protection program for personal computers and tablets running Windows 7 or higher because it is very effective at stopping malware from infecting your system, especially those attempting to download from online. It's a good solution for users that aren't too tech savvy since there isn't a lot of set up required. Kaspersky Anti-Virus is also a good deal because it comes with multiple user licenses to protect a minimum of three devices where other basic antivirus programs tend to come with only one. If you need additional security, such as a personal firewall, parental controls, password managers or a system vulnerability scanner, go with Kaspersky's internet security or premium software solution, but be prepared to pay a bit extra for these features. If you are a government employee, we strongly suggest you steer clear of Kaspersky all together.

4.5 out of 5

Kaspersky stops malware from infecting your computer by stopping malicious downloads and warning you of dangerous websites known to harbor malware. But if a threat does sneak by, Kaspersky Anti-Virus is effective at snatching it and permanently removing it from your computer so it can't reinfect your system. It doesn't cause too much noticeable slowdown while running, and while it earns high marks for protecting Windows 10 machines, Kaspersky Anti-Virus, is equally proficient in protecting PCs running other versions of Windows.
