On the other end of the spectrum, Kaspersky consistently got zero, indicating a very well-tuned detection engine.įinally, Avast scored 98% overall in both of the last two quarterly rounds of 2019 evaluations by London-based SE Labs (opens in new tab), which factors in false positives and how malware is handled after detection. In each half of 2019, Microsoft got 74 and 58, respectively, but suffered only five in February-March 2020 after AV-Comparatives turned off Microsoft's Smart Screen feature. In all 26 monthly tests carried out in 2018, 2019 and the first two months of 2020 by the German lab AV-Test (opens in new tab), Avast (and AVG) spotted 100% of both "widespread" known malware and "zero-day" unknown malware 14 times, which is commendable.ĪV-Comparatives' tests elicited more false positives than AV-Test's, and Avast performed adequately, racking up only five in the first half of 2019, eight in the second half and five in February-March 2020. Third-party lab tests reveal that both deliver acceptable but mediocre malware protection.
