I run a full system scan with my virus checker every Thursday. Yesterday It told me I was infected with "download.trojan", which is a backdoor program that may connect my system to web sites and download material/programs that I am unaware of.
Since I didn't have this trojan horse program 1 week ago, I stopped to think what I had been doing that was unusual.
I can't think of any new web sites or down loads that I've done in the last week that weren't related to music or websites pointed at from this forum.
I suggest everyone update their virus checkers and run a full scan.
I checked to make sure the forum itself was not affected. Its not, as download.trojan only infects Windows systems and this forum is on a Linux box. Possibly a link posted somewhere led to it.
