There are a variety of antivirus software applications available on the market, with some providing significantly more features than others. It is important to consider how much memory, CPU power, and compatibility the software will require when choosing an antivirus application. It is also a good idea to look for a program with the lowest cost and comes with a money-back guarantee.

When evaluating antivirus programs it is essential to check their virus-scanning and malware detection capabilities. For instance, it’s a good idea to find a program that uses heuristic-based detection techniques, which are able to detect malware even when the signature of the file is not known. Additionally, a reputable program will regularly update its malware database regularly so that it is able to keep up with new cyber-attacks.

Bitdefender Antivirus Free Edition offers an excellent solution for those on a tight budget. Its scans are quick and only take about 20 seconds to complete. It also scored 99.9% accuracy in tests performed by an independent lab AV Comparatives.

Macworld rated Intego VirusBarrier as a top choice for Mac users due to its compatibility with macOS and the ability to block its toolbars and windows. Macworld also found it to be a worthy choice because it detected all malware samples they tried during their tests and stopped the execution of these malware samples. It has additional security features such as disk optimization tools and parent control, but the nags for upgrading aren’t as threatening than its rivals.
