Overview

This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Aliases

• W32.MyLife.F@mm (Symantec)

• W32/MyLife.F (Panda)

• Win32.MyLife.F (CA)

• Worm/MyLife.F (Central Command)

• WORM_MYLIFE.F (Trend)

Characteristics

This mass-mailing worm is very similar to a previous variant detected as W32/MyLife.c@MM.

Written in Visual Basic 6, when this worm is executed a dummy error message is displayed (exactly as for W32/MyLife.c@MM)

It uses Microsoft Outlook to send itself to all addresses in the Outlook Address book and addresses on the MSN Messenger contact list. It arrives in an email containing the following information:

Subject: the list
Attachment: List480.TXT.scr

For example:

A dropped copy of the worm is executed at system startup thanks to the following Registry key:

 HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion_
  \Run "sys" = C:\WINDOWS\SYSTEM\List480.TXT.scr

If the worm is run when the minutes of the hour is greater than 50, the worm displays a message box and attempts to delete all files on the C: drive and to format drives C, E, F, G, H, and I. (This payload does not work on WinNT/2K/XP systems)

Symptoms

• Presence of the file List480.TXT.scr (7,680 bytes) in the Windows System directory.
• Messages in the Sent Mail folder matching the description described above

Method of Infection

When executed, the worm propagates itself to all addresses found in the Outlook Address book and addresses on the MSN Messenger contact list, using Microsoft Outlook. The worm copies itself to the System folder, modifying the Registry to run this copy at subsequent startup.

Removal

All Users:
Use current engine and DAT files for detection and removal.

Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

Additional Windows ME/XP removal considerations
