Editors' Note: We are aware of the allegations of Kaspersky Lab's inappropriate ties to the Russian government. Until we see some actual proof of these allegations, we will, and continue to recommend Kaspersky's security products as long as their performance continues to merit our endorsement. When you're looking to purchase, how do you know which is best? One help for your search comes from the independent antivirus testing labs, which evaluate and rate dozens of antivirus solutions. On that basis, Kaspersky Anti-Virus is a winner; it earned the top score in every test by every lab that we follow. The core protection is the same as what you get with Kaspersky's free product, but the paid edition includes bonus security scans and full access to tech support. The four independent testing labs I follow all include Kaspersky in their regular test reports. Kaspersky earned the highest possible score in every test by every one of the labs. I don't remember ever seeing that before. Bitdefender came very, very close, with just one score slightly below the very best. Kaspersky didn't fare as well in my hands-on malware protection test, but when results don't jibe, I defer to the labs and their dozens of researchers. At 8.5 of 10 available points, Kaspersky's score is OK. The best score against my current malware collection is 9.3 points, shared by and F-Secure. One way to fend off malware attack is to make sure the malicious software never reaches your computer. In my malicious URL blocking test, Kaspersky prevented the browser from even visiting over half the dangerous URLs. It wiped out roughly another 40 percent during the download phase, almost all just as the download began. Kaspersky's score of 92 percent is quite good, but a few competitors have done even better. Bitdefender recently earned a near-perfect 99 percent in this test, and managed 98 percent. Phishing websites don't host malware; they just trick users into giving away their login credentials. ![]() When I tested Kaspersky's ability to detect these frauds, it initially earned a truly dismal score, 44 percent. I have since learned that the developers had been working on the antiphishing servers at that time. When I ran the test again, Kaspersky proved extremely effective, using heuristic detection to foil frauds too new to be blacklisted. With 100 percent protection, Kaspersky beat out the built-in protection in Chrome, Firefox, and Internet Explorer. It also beat the competition. Bitdefender was at the top here, with 99 percent, while Trend Micro and come very close, at 98 percent protection. Kaspersky doesn't load up the free antivirus with bonus features, not the way AVG and do. It does install Kaspersky's VPN, but unless you pay for a separate subscription, you can use just 200MB of bandwidth per device per day, and you can't choose the VPN server. You do get an on-screen keyboard, to foil both hardware and software keyloggers, and the browser extension marks up dangerous links in search results. System Watcher and Ransomware The System Watcher component aims to detect malicious activity, including ransomware activity, in processes missed by the main real-time antivirus. To test this feature, I disabled real-time protection and launched a collection of real-world ransomware samples. I couldn't do that in my evaluation of Kaspersky Free, because in the free edition the protection settings are all locked in the enabled position. In every case, System Watcher detected suspicious behavior and blocked execution of the ransomware. That includes the uncommon disk-encrypting Petya ransomware that slipped past the equivalent feature when I disabled Bitdefender's regular real-time protection. Kaspersky didn't block my simple-minded fake ransomware program, but then, it really isn't true ransomware. I've occasionally encountered programs or program components that don't start early enough in the boot process, allowing ransomware that launches at Windows startup free rein. Kaspersky didn't fall for this trick. I also tried running KnowBe4's RanSim ransomware simulator, but Kaspersky eliminated the whole program as suspicious. Rescue Disk The Rescue Disk feature shows up as an extra-cost add-on in Kaspersky Free, but as far as I can tell it's free for anyone to download and use. It's a big download, a full ISO file at more than 500MB.
