"It's only more secure because it's a minority OS" - Jonathan Lane
No, no, NO, Jonathan. Read up on the issue before you post. Apart from the fact that, to be technically correct, there are no Linux viruses, and never can be, only trojans (that can only affect the user, not the OS itself - unless the user is stupid enough to be running as root) and vulnerabilities (e.g. buffer overflows and other exploits).
No-one ever claimed a single penny of the thousands of pounds offered by Eddie Bleasedale (NetProject Ltd) to anyone who could infect a properly-configured Linux machine with a virus - in fact, to the best of my knowledge, no-one ever tried!
And I'm always astonished at the stupidity of Windows users who read about Linux tools such as ClamAV (for removing Windows viruses from e-mail passing through a Linux server) and think that "anti-virus package for Linux" means that Linux viruses exist!!!
