Every once in a while I scan my host computer to check up on things and it found 3 things. 2 of which were from an early test of the Zeus Trojan network I found. (I forgot I had launched the file, oops). But Avast! also detected another file in my downloads folder. Images Album.exe. Detected as a Trojan backDoor.IRC. Is anything noticeable in a OTL scan?
Once installed on a PC the worm copies itself into a Windows system folder, creates a new file displayed as "Windows Genuine Advantage Validation Notification" and becomes part of the computer's automatic startup.
