If you started World of Warcraft today with Avast! running, which from what I have been telling you for a long time is the best AV out there, then you may have it as a positive reading from scan.dll and scan.dll.new. It's not completely a false positive, there are merits in the fact that they are detected, since they do actually scan your computer and then report the findings back to Blizzard. Thus they are trojans.
Though Blizzard is a safe company, I still took measures. I am not going to set Avast! to not scan these files, since I take malware very seriously. What I did instead was to rename the 2 scan files with an extension of .bak, then make 2 new files in the WoW folder using notepad and save as scan.dll and scan.dll.new. I set these as empty files and then set them to
read only.

This is nothing to worry about. We occasionally check the hardware specifications on your computer to know what types of computers our customers are using. Please be assured we do not check for any personal information. We're strictly looking for CPU speed, amount of RAM, video card information, and similar non-personal information.
Sorry Blizzard, but setting off my AV is not a good thing.
It is my opinion that should a trojan writer be smart enough, he will make an addon that auto replaces these after I mark them as "safe" and then I will have a real trojan on my system, that I marked as safe. I do not want to take these chances, and if blizzard doesn't get a little bit of information, so be it. I would rather be safe with my accounts.
Want Avast! Anti-Virus, the AV program that Spitt recommends?
