Had a look at my friends computer yesterday and found a few GBytes of Temp files in windows/temp (XP). However they were hidden and were apparently system protected files.

Having looked at my PC they dont exist so im wondering where they came from is it a virus or could it have been caused by another program. I didnt delete them as i wasnt sure if they existed on mine or not, i will now tell him its probably ok. Hes has Cubase installed on it anyone know if that does anything like that? To me it sounds virus/spyware related.

They had random jumbled up names ending in .tmp
