Antivirus performance comparison
Every computer user should consider installing an anti-virus program from a third-party source. These tools will help you identify and remove malware on the PC, and they can also block malicious websites that attempt to steal or corrupt data. However these tools can dramatically slow down a computer’s speed and performance when they are running a scan or updating their database with infected files. This article will examine the performance of different antivirus software in tests designed to assess how much they slow down a computer’s speed and performance when compared with other similar programs.
The independent AV Comparisons lab conducts a number of tests to assess the security software products. Its tests examine protection in real-world scenarios detection of infected files (classical testing) and performance, among other functions. The AV-Comparatives award Gold, Silver, and Bronze awards depending on the results of each test type.
This particular test was inspired by a real-life situation for a customer. Many customers employ complex PowerShell scripts to transfer content from one file system to another, and these processes can take several hours or even days to complete. These complicated scripts are run on high-performance equipment, therefore we wanted to see how the antivirus scanner impacted this. We also wanted to know how the tools used the resources on each computer.
Avira Prime scored well in AV-Comparatives ‘ tests, including 100% Mac malware and PUA protection and 100 percent Windows Malware detection. It requires a subscription to use all features. Its marketing messages are annoying.
