This memory-resident worm propagates by attaching a copy of itself to an email message, which it sends to target recipients using its own Simple Mail Transfer Protocol (SMTP) engine.

This worm searches the process list of the affected system for mrt.exe, the Microsoft Windows Malicious Software Removal Tool process. If found, it terminates the said process thus making the system more vulnerable to malicious attacks.

Been gettin' these all day long, too... and now within the last 30 minutes it's like email died -- no email, and I have TCH hosted clients reporting the same. Have submitted a support ticket about 20 minutes ago, but of course no reply since email is dead (though I am tracking it through the support web page).


Other than that, having a pretty slow afternoon....

Thank God for antivirus updates.


I informed all my address book to make sure they are updated and clean.


thanks TCH
