A lot of functions suddenly disabled

A few days ago I started my computer and found it restarting itself by no apparent reason, and when it was loading the desktop a "loading custom settings for: program\bifrost\server.exe" (a folder I managed to delete in failsafe-mode)

When I got into windows I had no start-menu (just a thin line I can't pull up), I can't copy or paste, open full-screen programs, sound drivers doesn't start, I can't see my own network (although I can still use Internet, which I find confusing), and a lot of other things which is VERY frustrating as I know I haven't got any suspicous programs or files down on my computer at the time this happened.

I'll just post my hijackthis-log and see what you can make of this. Thanks in advance.
