This is really great and helpful to people like me who are new to linux. I have successfully installed Avast antivirus software on my Ubuntu 7.10.

To, the administrator

"Buddy, you can issue the same with the name for Ubuntu 7.10, because i have tried it" 


You can check av-comparitives, avast detection rate is not what it used to be. Avira is killing avast and is available for free download, no registration.

and how do i instruct Avast to repair an infected file or quarentine a virus?


By: Jhourlad G. Estrella

Thanks to the developers and owners of Avast for releasing their hard-work to the world for free. So again it is basically FREE of charge, update is unrestricted, it basically scans executables as well as archives.

Pretty cool, huh? But what about real-time monitoring where files are scanned on the fly?

All of the antivirus programs for Linux I have found (Antivir, AVG, nod32) seem to need dazuko in order to provide real-time on-access virus protection.

Dazuko is a "stackable file system" and is a nightmare to install, if I understand right it allows the antivirus real-time access to the files being read/written. If you want to try to install it, I'd recommend trying first on a Linux installation that you don't care about (because you could mess it up, mine is limping).
