As reported my McAfee.comW32/APost@mm ("APost" or "New Backdoor") worm has been spreading over the past 24 hours through the Microsoft Outlook email program. This is a MEDIUM ON WATCH worm. The infected email can come from addresses that you recognize and may contain the following information:
----------------------------------------------
Subject: As per your request!
Body: Please find attached file for your review. I look forward to hear from you again very soon. Thank you.
Attachment: README.EXE
----------------------------------------------
Running the attachment causes the worm to copy itself to the Windows directory and send a copy of itself to every entry in the user's Microsoft Outlook Address Book. It will then display a small dialog box titled "Urgent!". This dialog box contains one single large button labeled "Open". If this button is pressed then the worm sends out further copies of itself, displays an error message box with the title "WinZip SelfExtractor: Warning" and then terminates.
