Windows 7 - Temp folder problem

Hi guys..

Well I got an issue with Windows 7 Ultimate x64 Temp folder.In few days it grows to 30 or even 50GB. I am doing disk cleanup every 7 days but I just cant make the temp stop filling with junk. Is there a way to fix this ?

Are almost all files starting with ~bd? And almost all folders with TMP?

Well yes actualy..

I would run trace program to see which program/service is writing all this. Could it be a virus, or some program went bananas writing in the endless loop. Have you look inside error logs? Did you look at system monitor and see what program is active more than others? Basically you need to identify what does all the writing and stop it, I don't think it's normal operation no matter what. Many programs use .tmp files, but they're temporary and are deleted automatically, not sure about BD: bullets? brush paint? database?
