Trojan horse PSW.Generic4.TUV in PATCH!

Thats right! There is a trojan horse virus in the latest patch. I was in my wow directory earlier this morning dealing with screenshots and had no problems. Then after the patch, I went into my wow directory and bamm, Threat Detected! says AVG. And yeah, I used Blizzard's downloader program to get the patch.

I refreshed my directory after moving the virus to my AVG vault and I got 2 more threats for 2 different patch files.. After that, the directory appears to be fine.... This is one of the threats.

So Blizzard, what is it exactly? Don't try to hide it, we know its there.. So own up to it and make things right.
