All-inclusive, comprehensive protection: avast! is a package of applications that aim to protect your computer from a possible virus infection or other malware threats. Free Edition is also available.
If you use it correctly and in combination with other programs such as data backup utilities, it will significantly reduce the risk of your computer being attacked or infected by a virus and thus the risk of losing important or private data.
