Hi user! :)
Do you know about any AntiViral programm for Linux?
How does it called?
Ive heard that Linux need not any antiviral - it cannt be infected.
Is it true? I dont think so...

Well, as you might know, linux has got restrictions to files, that are critical to the system, so they cant be edited by an ordinary user...
But wait a moment...
Who, in fact, edits the file?
Its not the user: Its a Programm!
And as we all know, virii are also programs, so...

However, if the virus manages to get suid root (by an exploit or whatever) or its run by a root user, its able to fulfill its destiny.

As I said, there MAY ba an exploit that gives the virus suid root, so theres always a possibility...
However, patching the kernel should work, because its the only program who can give suid root to a program (you could also open the harddrive and edit the filesystem directly, but thats also only possible if youre root).

So, just make sure you dont surf the web as root and youre 99,9% protected
(Of course, thats not the case with your personal data so dont forget to make backups)

Antivir is a goog program. On my SuSE 8.2 pro it is installed. You can get it from www.antivir.de (there is a Engish site, too). You can also disinfect files on windows partitions.
