This "100%" - is that only for a few minutes after startup, or all the time?
Have you checked your startup programs? Do you have lots of PUPs installed?
I would start by disabling some of the startups. But, if you do have lots of PUPs, you should get rid of them. MALWAREBYTES.ORG does a particularly good job of identifying and removing PUPs. And, it is free. Just download it and clean up your machine. I just ran that on a friends machine and it removed 234 PUPs. It took two passes, but the PUPs are gone. And, it may identify other viruses.
After that, let us see where you are.
