Hi, I'm getting the following error when I try to scan any attachment (by right-clicking on it and selecting scan using NOD32) "CRC check of nod32.exe failed, possibly due to infection" I have run the NOD32 on demand scan and it found nothing! Then upon rebooting, NOD32 on demand scanner detected 3 trojans and presumably sent them to quarantine, but still I'm getting the same error when I try to scan any attachment! I have run spybot and ad aware, same thing!!! Ad aware finds the trojans quarantine them , but the problem persists! HJT does not show any suspicious files... (I gues thi strojan inflitrated NOD32 exe files and corrupted them). I even uninstaled and installed NOD32 from scratch, but I'm still getting the same problem!! Any help is appreciated. P.S. NOD32 is up-to-pdate and has the latest definitions!
