So I've did research and figured out that spoolsv.exe is actually a service that came with Windows and has something to do with your printing queue but also a known Trojan.
Things I've tried out:
Restarting my computer: No effect
Stopping the proces: Solves the problem until it restarts himself again. (Which is within a minute.)
Turning the printer on/off: No effect.
Clearing all my print jobs in queue: There weren't any jobs in queue, so no effect.
Scanning on Viruses/Spyware: Tried Panda Platinum, Windows Defender and Hitman Pro (A compilation of all well known free scanners) and they found nothing. No effect and 4 hours of my day wasted with waiting in front of the computer.
Removing all printers with the exclusion of the default one: No effect.
Disableling the printer queue: No effect.
Restarting the Printer Spooling service: No effect.
Disableling the Printer Spooling service: Has effect, but now I can't print anymore which isn't good either. (Yes, I'm a very demanding guy.)
Removing all the printer drives and reinstall them: No effect.
Removing any files in System32 that should cause problems with the Spooling service: None found, no effect.
Is there anyone that has some other solutions? Because I think I'm going to cry now...
