Avast is one of the most popular antivirus programs available on the market. It is also a paid program. Windows Defender is the built-in antivirus program that comes pre-installed on Windows 10 and 8.1.

Windows Defender is free, but it does have a few features that are not available in the paid version of Avast. For example, Windows Defender can detect and block malware that is using advanced techniques. The paid version of Avast also has a few features that the free version of Windows Defender does not have, such as the ability to scan for updates automatically.
