Why do they even have anti-virus for Mac OS X even though THERE ARE NO VIRUSES FOR OS X ANYWAY!? Well, I almost wasted my money...Contrary to popular opinion, *NIX systems may need to run anti-virus soft. Even if these WinVirii(tm) can't actually affect the *NIX system, you still need to prevent "pass through" where the *NIX infects Win systems connecting to it. This would, of course, include *NIX mail servers.
I have 20 viruses on my computer... They're WIndows viruses and it's a Mac! No problem.If this were a server, then it
would be a problem, not for you, but for others. Not terminating these virii would not be good "Netizen-ship".
Speaking of WinVirii(tm) and *NIX, check
