Technical description:
VBS.VBSWG2.X@mm sends itself to all recipients in your Microsoft Outlook address book. The email message has the following characteristics:

Subject: Homepage
Message:
Hi!
You've got to see this page! It's really cool ;O)
Attachment: Homepage.HTML.vbs
Prior to mailing itself out, the worm searches for email messages with the Subject of Homepage; if found, it deletes them. After mailing, the worm creates the registry key
HKEY_CURRENT_USER\Software\An\mailed
and sets it equal to "1". The presence of this registry key prevents the worm from running the email routine more than once.
The worm then randomly selects one of four pornographic Web pages and opens it.
Removal instructions:

To remove this worm:
1. Run LiveUpdate to make sure that you have the most recent virus definitions.
2. Start Norton AntiVirus (NAV), and run a full system scan, making sure that NAV is set to scan all files.
3. Delete any files detected as VBS.VBSWG2.X@mm.

It is not necessary to remove the registry key that the worm added.
