Mails with 30kb zip attachment - virus?

[OlRedEye]

Have been recieving mails with these attachments for weeks now. Seems to remail themselves from my accounts - 2 have been returned undelivered. Anybody know what they are?

Could be Virus best bet would be to have an antivirus on your computer, even a free one like AVG.

On another point its easy for someone just to spoof your email address, and when the server recieves the email and detects the virus, it will just return it to the spoofed address in this case your email address.

Virus /Worm "Bagle" does this, the undelivered messages may not be from you but from an Outlook address book (where you appear) from the infected computer.
Have a look at the IP.
Not much to be done once you are sure you are not infected
