Antivirus performance comparison

All computer users should think about installing a third-party antivirus software. These tools can help detect and eliminate malware on computers, and can also block malicious sites that may try to hijack or corrupt data. However they can drastically slow down a computer’s performance when running an analysis or updating their database with infected files. This article examines the performance of different antivirus programs by testing the extent to which they can slow down a computer.

The independent AV Comparatives lab performs a large number of separate tests to test security software products. Its tests focus on security in real world scenarios, detection of files infected (classical testing), performance and many other functions. Each test type is run multiple times over the period of one year. according to the results, AV-Comparatives issues Gold, Bronze and Silver awards to security solutions.

This particular test was inspired by an actual customer scenario. Many customers use complex PowerShell scripts to dump files from one file system to another, and these processes can take a few hours or even days to complete. These scripts are complex and run on high-performance equipment therefore we wanted to determine how the antivirus scanner impacted this. We also wanted to know how the tools used the resources on each computer.

Avira Prime scored highly in the AV-Comparatives tests, which included 100% Mac malware and PUA protection, as well as 100% Windows Malware detection. However it requires a monthly subscription for full functionality and its marketing messages are often quite irritating.
