To automatically run itself each time Windows is booted, the Virus adds the following link to its file to the system registry autorun key:

[HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run]
"XP-542ADE6B" = "%System%\XP-542ADE6B.EXE"

Network activity (URLs)

No activity has been detected.

HOSTS file anomalies

No changes have been detected.

Rootkit activity

No anomalies have been detected.

Propagation

A worm can spread via removable drives. It writes its executable and creates "autorun.inf" scripts on all removable drives. The autorun script will execute the Virus's file once a user opens a drive's folder in Windows Explorer.
