When choosing an antivirus program it is essential to know the extent of your computer’s resources the software will use. The best programs have only a minimal impact on system performance while providing superior security against malware and viruses.
Most antivirus software vendors publish extensive tests in PDF format. The reports give a quick overview of the security, performance, and usability of each suite. They also contain detailed charts and graphs that show the results of various tests. The percentage of real-world malware and exposures to reference sets that the program blocks, neutralises or compromises, along with the amount of false positives that are detected of malicious programs, are important figures to look out for.
In AV-Comparatives’ tests from June 2023, Avast Free Antivirus for Mac had the highest rate of success in blocking Mac malware and PUAs (potentially unwanted programs) and the second highest score for Windows virus detection. It also scored highly for the categories of full-scan, passive, and quick-scan.
When compared to paid programs, Bitdefender Total Security had the lowest post-installation background system impact being followed by Kaspersky Total Security and ESET Security Cloud Free. It was the slowest on both quick-scans and full-scans. The program’s minimal impact on the background could be because it doesn’t run as a default application on Windows 10 or 11, like most of its competitors.
Intego had the lowest system impact for background and full scans, but it still managed to detect every piece of malware. It’s rare to find a company which solely focuses on Macs. This makes it a useful option for any security arsenal.
