Trajon Files Left in the System Folder

This section provides detailed information on malicious files left by two Trojan attacks. Somehow McAfee failed to detect and delete them.

After finish review the McAfee VirusScan log file, OnAccessScanLog.txt, I started to look at the system folders to see files left by the Trojan.

In c:\windows, I saw the following new files:
