It’s crucial to know how many computer resources the antivirus program will consume. The most effective software is one that has minimal impact on system performance while still providing excellent security against viruses and malware.
The most respected antivirus software companies have extensive test software that is widely published in PDF format for download. The reports give a quick overview of the security as well as the performance and usability of each suite. They also provide detailed graphs and charts that display the results of a few test elements. The percentage of real-world malware and reference set exposures that the program blocks, neutralises or compromises, as is the amount of false positives that are detected of malicious programs, are key figures to watch out for.
Avast Free Antivirus had the most impressive scores for Windows virus detection in AV-Comparatives tests conducted in June 2023. It also had the highest rates of success in blocking Mac malware. It also scored highly in the categories of full-scan, passive, and quick-scan.
Among paid programs, Bitdefender Total Security had the lowest post-installation background system impact which was followed by Kaspersky Total Security and ESET Security Cloud Free. It was the slowest on both quick-scans as well as full-scans. The program’s relatively low impact on background could be because it doesn’t run as a default application on Windows 10 or 11, like the majority of its rivals.
Intego had the lowest impact on systems for background scans and full scans, however, it still managed to catch every bit of malware. It’s not often that you find a company that solely is focused on Macs. This makes it a useful addition for any security arsenal.
