‘There are no viruses for Linux’ is (to my limited knowledge) a true statement.

However (again, to my limited knowledge) it is not the same as ‘bad things associated with malware don’t happen under Linux’.

Browser hijacks happen, as a quick search on the ubuntu forum will reveal. They always seem very easy to remedy under Linux, but if you don’t happen to know how they will still spoil your day.

Cross platform malware (java/flash exploits) are presumably relevant (at least that’s how I read it), though presumably more limited in scope.

If you’re really ill-advised or incautious I gather you can even let yourself be persuaded to install a trojan such as BackDoor.Wirenet.1 and have all your passwords stolen.

So I think there can be other reasons for an anti-malware scan of a linux OS (Home folder at least) than Old-Polacks suggested ‘email to be forwarded to Windows computers’.

Ill-advised and incautious people exist, and some no doubt use Linux.
