This is another new variant (.r) of W32/Netsky@MM. It arrives
as an e-mail message with the heading "Document {number}," where {number}
is a random number. If the attached .PIF file is opened, the worm infects
the machine then uses e-mail addresses from the local address books to propagate.
Recommended Action:
Do not open email attachments as described above. To stop
this virus, Network Associates (McAfee) DAT Level 4346 is required. Visit
