I just dug up an old file I had in my quarantine that was listed as "probably unknown STEALTH.POLY.CRYPT.TSR.DRIVER virus." I recently discovered these forums as well as the virus total website. This is what it came up with: http://img.photobucket.com/albums/v602/anthunit/virus.jpg I remember telling NOD32 to submit it to ESET probably about a month ago. I'm not sure exactly what the protocol is but I imagine if it was a false positive or a genuine virus and they actually received it from me there would have been some kind of definition update or something. Can someone please clarify how the process works for me and what I can do to get the file analyzed? From the description NOD32 gave me of the infection it sounds pretty nasty.
