It’s crucial to understand the amount of computer resources your antivirus program consumes. The best antivirus programs will have very little impact on your system’s performance but still offer excellent protection against viruses and malware.

Most antivirus software companies publish comprehensive tests in PDF format. The reports offer a brief overview of the security as well as the performance and usability of each suite. They also provide detailed charts and graphs that show the results of various tests. The try this out percentage of real-world malware and references set exposures that the program blocks, neutralises or compromises, as well the number of false positives detected of malicious programs, are crucial figures to keep an eye 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 passive, full-scan and quick-scan.

When compared to paid programs, Bitdefender Total Security had the lightest post-installation background system impact which was followed by Kaspersky Total Security and ESET Security Cloud Free. However it was also the slowest in the full-scan and quick-scan categories. Its minimal background impact might be due to the fact that the program does not run by default on Windows 10 and 11, as its competitors do.

Intego had the lowest system impact for background scans and full scans but it still managed to detect every piece of malware. It’s rare to find a company that solely focuses on Macs. This makes it a great tool for any security arsenal.
