I’ve devised an algorithm to normalize all four to a 10-point scale and derive an aggregate lab score. The four labs use very different scoring methods, making comparison challenging. Avast reaches level 2 in the latest test only Bitdefender and Malwarebytes manage level 1. Those that let some malware attacks through initially but remediate the situation within 24 hours reach level 2. Those that completely prevent every attack earn level 1 certification. In a separate test using all types of malware, antivirus tools get two chances. Just over half the products in the latest test fail, including Avast and Trend Micro Antivirus+ Security. Products that don’t reach a near-perfect score in its banking Trojans test simply fail. London-based MRG-Effitas is a tougher taskmaster than the rest. In the latest round of testing, Avast reaches the AAA level, along with all the other tested products except for Webroot SecureAnywhere AntiVirus, which manages AA-level certification. Products can earn certification at five levels, AAA, AA, A, B, and C. To evaluate an antivirus tool’s real-world protective abilities, the testers at SE Labs (Opens in a new window) use a capture and replay system to hit each tested product with the exact same web-based attacks. Like AVG and Bitdefender Antivirus Plus, Avast takes Advanced+ in all three tests. I follow three of the many tests from this lab’s reports. Those that exceed the minimum needed to pass can rate Advanced or even Advanced+. Any product that passes one of this lab’s many tests receives Standard certification. Almost all the remaining products manage 17.5 points, enough to receive the label Top Product.Īt AV-Comparatives (Opens in a new window), researchers don’t assign numeric scores. Along with AVG AntiVirus Free, Microsoft Defender, and a half-dozen others, Avast earns a perfect 18 points in this lab’s latest round of testing. A product can earn up to six points in each area, for a maximum of 18. Testing experts at AV-Test Institute (Opens in a new window) rate each antivirus in three areas: protection against malware attack, low performance impact, and minimal false positives. And Avast’s scores aren’t merely plentiful most are impressively high. More than half of them don’t show up in any current reports or appear in just one. Only four of the antivirus products I follow appear in current reports from all the labs, Avast, Avira Free Security, Bitdefender, and Microsoft Defender. The mere fact that all four labs put it to the test shows that Avast is a significant product. Since you can get Avast One Essential for free, though, it doesn’t make a lot of sense to choose the older Avast Free Antivirus instead. All of Avast’s existing software remains available for download or purchase. However, the latest version, reviewed here, is strictly for the US for now. The Avast One software line is available in the US, the UK, Canada, Australia, France, Germany, Austria, and Switzerland. That makes Avast One Essential a clear Editors' Choice award winner for free antivirus software. You can use it on all your Windows, macOS, Android, and iOS devices. It goes on to add many components from the full-featured (and not free) Avast One suite. Avast One Essential starts with the powerful virus-busting tech that’s always been its forte. How do you follow an act like that? By offering more than basic antivirus while keeping the price at zero. If one of them is Avast, that's not surprising, given that the company has been offering free antivirus protection for more than 20 years. Quick, name three free antivirus products.
