Grab Macrium Reflect free and make an image of each drive to an external drive before you go any further.
Grab a copy of adwcleaner ToolsLib - Downloads - AdwCleaner . It was bought by Malwarebytes. Run it and clean anything it finds. I've used this program many times to clean up PUPS, malware etc.
Sounds like you drive is just full? Right click on the drives properties and run a disk cleanup. Uninstall any programs that you don't need. etc.
