Recently I have been receiving MAILER-DAEMON Returned mail:user unknown Emails, without sending any mail. Fearing a virus or some other scam, I delete these without opening. Wondering if anybody else has experienced this. Maybe it's just a glitch in all these electronic web thingies?...Jack

Most likely, someone is using your e-mail address as a "spoof", so that it looks like you have sent the e-mail, then it tries spamming all these invalid addresses and you are the lucky recipient of all the "delivery failure" messages. It happened to me and for about a month, I got on average about 200 "delivery failure" messages per day. My ISP could care less, so I was tempted to just let them fill up my mailbox (I quit using the ISP required e-mail account anyway), but then I figured they'd punish me, so I dutifully checked the e-mail and promptly deleted everything.

Usually, If I send email to someone and it takes a few minutes later it returns to my email with "Mailer-Daemon Email". It's okay to open email but never open if you don't send email to someone's email. If you were still online for a long time. That's mean you are safe. Never open email if you don't sent email or more than a few hours later. Do not open email.

The returned mail does not contain the sobig.f worm, it means the worm has your e-mail address in its file and is sending mail with your address. Just delete all the notices, your e-maill address book and let people know you will be changing your e-mail address.
You'll have no luck with a virus scan as it is not a virus. It has your address and uses it. The only option is to change. Make it over 11 characters and containing numbers and letters. You'll be OK then.
