When looking at antivirus programs when evaluating them, it is crucial to examine their virus scanning and malware detection capabilities. It is important to look for a program which uses heuristic detection methods. These methods can identify malware, even if its signature is not known. A reputable program will update its malware database regularly to keep up with most recent cyber threats.

Bitdefender Antivirus Free Edition offers the perfect solution for users on a tight budget. Its scans are swift and only take 20 second to complete. It also performed well in tests conducted by independent lab AV-Comparatives, with a 99.9 percent accuracy score (although it does not have a firewall, cloud backup or VPN, which is why it’s not recommended as a stand-alone security solution).

Macworld found Intego VirusBarrier to be a top choice for Mac users, thanks to its remarkable compatibility with macOS and ability to disguise the appearance of its windows and toolbars. It also scored well in tests conducted by Macworld and was able to stop all the malware samples they tested the program, and preventing the samples from being executed. It also has a variety of additional security options like disk optimization tools and parental controls, although the nags to upgrade aren’t as aggressive as some of its competitors.
