While the Windows Google Drive program is running, it creates folders called C:\Users\[username]\AppData\Local\temp\_MEInnnnn (where "nnnnn" is a 5-digit number). They contain python scripts and other things. They're usually created at startup, and removed tidily upon exit, but sometimes persist (I've taken that up with Google). But I'm writing here to say that Combofix removes them. (False Positive?)
I'm running Win7Pro/64-bit.
