Antivirus Performance Comparison

When choosing an antivirus software, security experts and consumers alike look at a myriad of factors in addition to the software’s protection capabilities. Things like cost and system impact, usability, compatibility and the personal judgment of the company’s practices are all crucial aspects which can play a significant role in determining whether a person should pick an antivirus software.

Germany-based Avira is a great option for those who require an antivirus suite that provides solid test results and the option of billing monthly. Avira’s antivirus program is renowned for its high scores across all categories. It also comes with an array of useful extras, such as a password management tool. Avira’s scanners have a slight background effect, and aren’t particularly resource-heavy. However, the full-scan speed decrease is quite significant at 53% which is among the most hefty in our tests.

Our top picks aren’t the best. For instance, Kaspersky’s hefty background effect can lead to slowdowns that can reach 53%, while Avast’s full-scan slowdown is only slightly less at 44%. On the other one hand, Bitdefender has an excellent free version as well as a powerful subscription-based antivirus solution that has excellent independent lab scores. Its features include an VPN and is extensive, which makes it stand out from the rest of the competitors.

The top-rated paid AV software include F-Secure, McAfee Total Protection and Trend Micro Internet Security. Microsoft Defender, the built-in antivirus that is included with Windows 10 and 11, is relatively light, only having an impact on the background of 9%. However, it could cause heavy system slowdowns when performing full system scans.
