Antivirus Performance Comparison

Security experts and consumers alike take into consideration many aspects when selecting an antivirus software, besides its security capabilities. Things like cost, system impact, usability, compatibility and personal opinion of the company’s practices are all crucial aspects which can play a significant role in a person’s decision to choose a particular antivirus tool.

Avira is a German company. Germany is a fantastic option for anyone seeking an antivirus software that can provide excellent test results. They also offer the option of billing monthly. Avira’s antivirus program is renowned for its high scores in all categories. It also comes with many useful features like a password management tool. Avira scans are light and do not use many resources. However, the full-scan speed drop is quite substantial at 53 percent, which is one of the heaviest in our tests.

Our top picks aren’t perfect. Kaspersky can slow down your computer by as much as 53% with its heavy background effect, whereas Avast is just a bit slower at 44%. Bitdefender however, on the other hand has a great free version, as well as an AV subscription solution which has excellent independent test lab ratings. Its feature set is extensive and includes a VPN, which helps it stand out from its competitors.

The top-rated paid AV applications are F-Secure, McAfee Total Protection, and Trend Micro Internet Security. While Microsoft Defender, which is built right into Windows 10 and 11, has a relatively light post-installation background impact at only 9%, it’s also vulnerable to slowdowns that are severe during full system scans.
