I have two email accounts, Hotmail and my POP3 account, which is only known to about three people! In the last three days I have received about 20 emails a day into the POP3 account, with either attachments, or just suspect mails with "mail delivery failure" in the subject line. These have mainly been quarantined automatically by AVG, and all have been deleted without opening. They contain variants of the Netsky virus.
I am running XP Pro, with AVG, ZAPro, SS&D, Spyware Blaster, IE Spyad, Spyware Guard, Ad-aware and pestPatrol.
Is there any particular reason why my POP3 account is being targeted, and is there any way I can stop it?
