The only thing I've done in the past day (since last scan) is install vmware player and download Ubuntu 11.04 and TinyXP. I just did a scan of TinyXP because I scan EVERYTHING I download, even if it's a txt file. And when MSE opened it said "Potentially Unprotected" After scanning TinyXP it showed this file: Win32/cmdow but I'm sure it was there before I scanned TinyXP. What is this file? Is it bad?
