Avast Free Antivirus is a package of applications that aim to protect your computer from a possible virus infection or other malware threat
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. Avast Free Antivirus comes with a completely revamped user interface for easier scanning. The user interface enables you to check the current status of your protection, to adjust the program settings and to carry out a manual virus scan. Unless you want to perform any of these actions, you may never need to access the user interface at all as once the program is installed, the resident shields will be silently and continuously protecting you against threats from viruses and other malware.
