Hi, I am using the latest version of Nod32 v2 with latest updates and latest updates of xp. I schedule virus scan every week, and every time it say that it detects this C:\WINDOWS\Downloaded Program Files\WinadX.dll - Win32/TrojanDownloader.Small.NAS trojan. It's being highlighted as red. I am not sure if it's being deleted by Nod32 and then come back again. But Nod32 complains the same thing every single week. I used spybot and lavasoft, but they can't detect it. When I go to the directory to check out the Winadx.dll, it's not there even though I set xp to view all hidden & system files. Please help. This thing is driving me crazy. Many thank.
