Like Avast is Free and ESET NODE32 is a paid antivirus. Now a days many security experts think that bare antivirus is of no use. But still some vendors are selling them as a paid product. So it is a matter of debate. Because now Windows defender which comes free with Windows operating system also provides almost same level of security. So there is no use of standalone antivirus.

This is a powerful approach to stopping even unknown types of malware. Malwarebytes and Hitman Pro are examples of anti-malware software. This feature is included in the core security of modern antivirus software. So all modern antivirus software includes behavioral technology with antimalware capabilities.

3) Machine learning antivirus

To improve the detection of unknown threats, developers are attempting to incorporate machine learning or artificial intelligence. Despite the fact that these experiments are still in their early stages, some antivirus companies are already incorporating this technology into their security suites. And it will be a milestone in the fight against modern malware threats.
