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.
