Post a HijackThis log here so we can see what's installed and what's running in the background.

Just because you ran a virus scan and it came up clean doesn't mean your computer doesn't have malware.

Download and install Malwarebytes Anti-Malware 1.38 as advised, get it up-to-date with the latest definition files, run a scan with it(which will take 7 - 10 minutes), allow it to select and fix everything it finds, then post its log here.
