The most important thing is a reliable antivirus engine. Every antivirus program has to be able to recognize threats with high accuracy. However, other factors can assist with this, including a strong heuristics detection engine as well as behavioral-based protections. You should also make sure any antivirus program includes a lot of anti-malware security signatures in its database, and a robust and extensive set of scanning methods.

Windows PCs and Macs both come with built-in antivirus software, but it’s usually not as efficient as a third-party application. It’s not always up-to-date and can result in being unable to detect threats. It’s also missing many of the security features that make third-party antivirus so beneficial. These include parental controls, advanced phishing protections, and web-based security features.

Avast, Norton, and Kaspersky are the top three antivirus programs available. Avast’s program is simple to use and has high malware detection rates, according to an independent lab AV Comparatives. But the parent company was discovered selling user’s anonymized data through its Jumpshot service in the year 2019 and hasn’t fully cleaned up its business since it was discovered. Kaspersky offers a similar alternative, offering a decent malware-detection rate and a variety of internet security options, including memory fire walls and banking tools as well as VPNs.
