Comment 74 for bug 365881

I'm not 100% sure, but I think pyrun.exe is some sort of python language interpreter. Wubi is written in Python. I could be wrong, though. You're the first person in this thread who has had AV problems with pyrun.exe. The rest of us were trying to get pyrun.exe to stop giving us a "no disk in drive" error every time it encountered a card reader slot.
