Subject: Returned Mails

Hi,

This is probably a stupid question but I could do with some
confirmation 
of what I think is happening. I've been receiving a lot of 'return'
emails 

Result: Virus Detected
Virus Name: W32.Netsky.C () mm
File Attachment: posting.txt.com
Attachment Status: deleted

The message you have included shows it was infected with NetSky/C-MM and
as this worm (in common with almost all of the recent mass mailers)
always fakes the from line it is fairly safe to assume that the one
place this mail did not originate from is you. Now if the administrators
of the "helpful" mail servers sending you these returns could be
convinced of this and innocent users could be spared the millions of
unnecessary AV spam messages these outbreaks generate the net would be a
much happier place.
