I got hit with a stupid IRC virus recently. It's called Backdoor.IRC.Zcrew. If you already know about it, then great; if you don't, then this notice is for you. It's very easy to tell if you have this virus or not. I recommend for safety's sake you look for it and confirm you don't have it. Follow this Symantec link:

It explains very clearly how to detect and rid yourself of the offensive bug.
