Security experts and customers alike take into consideration many aspects when selecting an antivirus software, besides its security features. Things like cost impacts on systems, usability, compatibility and personal opinion of a company’s business practices are all important aspects which can play a significant role in a person’s decision to choose a particular antivirus tool.
The German-based Avira is a good option for anyone looking for an antivirus suite with solid test results and the option of monthly billing. This antivirus program has impressive lab scores in every category and comes with numerous useful features such as a password manager. Avira’s scans feature a subtle background effect, and aren’t very resource-intensive. However, the full-scan speed drop is quite substantial at 53% which is among the heaviest in our tests.
It’s a challenge to choose the most effective free AV program since many of our top choices come with a few disadvantages. Kaspersky can slow down your computer by as much as 53% thanks to its powerful background effect, while Avast is only a little slower at 44%. On the other side, Bitdefender has an excellent free version and a robust subscription-based AV service that has superb independent testing lab scores. Its feature set is extensive and includes a VPN, which helps it stand out from its competitors.
F-Secure is the best-rated paid antivirus program. McAfee Total Protection and Trend Micro Internet Security are also highly rated. Microsoft Defender, the built-in antivirus that comes with Windows 10 and 11, is comparatively lightweight, only having an impact on background of 9%. However, it may cause significant system slowdowns while performing full system scans.
