Avast Antivirus is an anti-virus program developed by ALWIL Software based in Prague, Czech Republic, first released in 1988. avast! is used worldwide and is available in 27 different languages. It is loosely based on stereotypical pirates (the name "avast!", and the fact that it has a virus chest instead of a vault). Since its release, avast! 4 Home has become one of the most popular full-featured freeware anti-virus applications for Microsoft Windows users, almost reaching 6,000,000 downloads on Download.com.
The program is free for home and non-commercial use so it is often compared with the free version of Grisoft's AVG Anti-Virus.
The software is aimed at preventing several types of computer threats, including those that are not technically computer viruses such as spyware and even rogue anti-spyware, and can also make a virus Recovery DataBase which is used to recover files when they are infected (instead of just deleting them). The product can be downloaded with full text and voice translations to more than 25 different languages.
Avast! 4 Home Edition is a full-featured antivirus package designed exclusively for home users, non-commercial users. Home Edition is free of charge, since in our opinion, it is possible to avoid global virus spreading by efficient prevention; however, many user are not able or do not want to pay for antivirus software.
