Security experts and users alike take into consideration many aspects when selecting an antivirus program, in addition to its protection capabilities. Things like cost as well as system impact, usability, compatibility and personal judgment about the company’s business practices are all crucial aspects that can play an important role in determining whether a person should choose a particular antivirus tool.
The German-based Avira is a great choice for anyone in need of an antivirus suite with solid test results and the option of monthly billing. This AV program has impressive lab scores across all categories and also provides numerous useful features, such as a password manager. Avira scans are lightweight and do not consume lots of resources. However, the speed drop is quite substantial at 53%, which is one of the heaviest in our tests.
A few of our top choices aren’t the best. For instance, Kaspersky’s strong background effect can lead to slowdowns that can reach 53%, whereas Avast’s full-scan slowdown is only slightly lower at 44 percent. Bitdefender however, on the other hand, has an excellent free version as well as an AV subscription solution that has excellent independent testing lab ratings. The features it offers are extensive and includes an VPN which makes it distinguish itself from other competitors.
The top-rated paid AV software include F-Secure, McAfee Total Protection and Trend Micro Internet Security. While Microsoft Defender, which is integrated into Windows 10 and 11, has a fairly light post-installation background effects at 9%, it’s also vulnerable to slowdowns that are severe during full system scans.
