Hello Daan mate first up if you haven't done so already run these
SFC /SCANNOW Command - System File Checker
Disk Check < if necessary include the /f and /r in the command line as per Option2 - in safe mode
if that doesn't do anything try these
SUPERAntiSpyware | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!
Malwarebytes | Malwarebytes Anti-Malware Premium
AdwCleaner Download
ADW download from bleeping computer delete any rubbish found with the malware scans
and I would also be checking to see if the Windows firewall in the control panel was on or off.
Having said that Teamviewer really isn't that much of a threat I wouldn't have thought.
