I have been battling this for some time now. I've used Norton, AVG and Trend. Originally, the machine had files that showed Elkern and Klez. All are gone. All virus programs have done full scans and find nothing. Yet, there is email automatically being sent from my address, bouncing back to me. The subject headings are the usual mish mash of things like Japanese girls etc. Mailer-daemon bounces them back to me. Computer otherwise seems to be ok, but I would like to stop the email stuff. Suggestions for what to look for in registry or other locations? thanks

Run through the info that KimberTech provided just to be sure - it won't hurt anything. But you may not be infected. Klez spoofs the from address with an address from the infected computer's address book. Here's an excerpt from the link KimberTech provided:

Recipient e-mail addresses are collected from the Windows Address Book as well as from ICQ user databases. The worm uses it's own SMTP routines so it can send e-mail without an e-mail client.

Important Note: The e-mails sent by Klez.E worm often have faked sender's address. The worm randomly picks sender's address from web pages, ICQ databases or Windows Address Books. This means that if you get Klez.E worm in e-mail, it's quite likely that it was NOT sent to you by the person listed in the 'From' field of e-mail message (sender's address).


It's quite likely that someone you know is infected and sending using your e-mail address, which is getting bounced (back to you) for whatever reason.
 
It also may just be the backlash from the intial infestation. My machine had a virus one time, I knew it right away, ran a scan and clean, but still received emails six months later as the messages finally "bounced" back from the receiving end... Terry
