Operation
Agent.AWF displays virus activity in that it replaces files on a user's computer with a copy of itself, and moves the original, legitimate file to a back sub-folder. It is known to attempt to terminate security software, and the Trojan downloads a backdoor onto the computer, allowing the attacker to further compromise the computer. It is also known to modify the Windows registry. Agent.AWF does not spread automatically: it needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, emails with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc. Identification
During installation, the following files are created, and may be present on a compromised system. abc123.pid
