Whenever I connect to MIRC, I find this virus as well when I run the online scanner. However, I also get about 50 connection attempts from 69.50.181.165 hitting different ports, wanna.see.a.massdeop.us, MAIL.ATRIVO.COM . If you open tha secondt website address, there's a bunch of pictures and a video of some sort of party... I don't know if the two are related, however for me they did appear around the same time.
