I would be carefull with using Loaris as I just ran it and it claimed to pick up 14 Trojans.
I haven't as of identified what all 14 files are for, however several of the files picked as Trojans are for a program called Nero.
One of the identified Tojans being advrcntr2.dll on which I just did a search in google for and from I have seen it is legitimate and is required for Nero.
I haven't as of yet used Nero, it came installed with the computer from the shop, I believe it's for burning CD's.

Post updated again,
Loaris doesn't like WOW either, it freezes on scanning one of the WOW exe files.
Yep - it's Loaris Trojan Remover, which I fortunately picked up cheaply this weekend,

There's a free trial which will identify infections but won't remove them. Still - it's better to know, I think.
