I tend to agree with dodger - perhaps the hardware/technical forum would be a better place to discuss viruses. as there are over 600,000 known windows viruses, trojans, worms, r.a.t.s, spyware etc., this topic could easily consume this forum if we're not careful. being on mac OS, I'm also concerned with security issues. so far there are 3 known OS X worms, 3 concept trojans, 2 malicious trojans and 1 rootkit. these have all been covered by recent OS X updates, but the place we always discuss them is the mac forum, so as to avoid cluttering this forum with irrelevant info.
