edit:
Woah woah woah
This was not at all windows' fault. Or a virus. (even though i found a few adwares on my adventure)
It was actually something I downloaded.
It didnt like it so I removed the files, it was a desktop thingy, but something else was trying to execute it.
Every time I clicked the desktop, it wouldn't see the files, and it would freak out.
It just told me, "we cnt find so we disable" and it didnt crash anymore.
