Hi everybody. Yesterday, I tried to send a message using my Hotmail account and always got a "delivery failure notification" reply from Hotmail, quoting my original message but giving no explanations about the error. I tried like five times and always happened the same. I decided to try using my Outlook Express account and everything seemed to work fine. The weirdest thing is, after sending the message using my Outlook, I received this message in my Hotmail inbox: From: <ISA@GMHC.org> Subject: Symantec AVF detected a repairable/quarantined virus in a message you sent Subject of the message: Mail Delivery (failure lynns@gmhc.org) Recipient of the message: Lynn Schulman My message wasn't sent to that person. In fact, it has nothing to do with my original message, but it is VERY strange. After that, I tried sending another message from my Hotmail account to my recipient letting him know what happened and it was successfully sent. My original message had no attachments. Only some hyperlinks to sites I know and trust 100%. Coincidence? Any input on this is highly appreciated. Thank you in advance. Regards.

Forgot to mention: I don't have Norton Antivirus. I ran a virus scan using AVG and also checked for spyware using Ad-Aware and Spybot. Everything is OK.

It is likely the "Mail Failure" messages did not originate from your machine. Someone who has your address in their addressbook has become infected with one of the netsky variants and it is dumping these things in your mailbox in the hope you will open it and infect yourself. Ignore them and delete them without opening.
