Watch out... It's called the W32.Sobig.F worm. It came to my inbox, as a file attachment labeled "dmyongsa.exe". "Failure Letter" was in the subject line from a sender called "MS Network Storage Service" at mailprogram@america.net. DO NOT open the attachment, just delete the entire message. If you already opened it, or you think that you may have it in your system already, then visit the following page to remove the thing: http://securityresponse.symantec.com/avcenter/venc/data/w32.sobig.f@mm.removal.tool.html
