|First of all, download and run Ccleaner Slim|
That will clean out all the excess junk on your PC and make the next scans go faster.
The best and easiest way to clean it up is to run Malwarebytes (update it and then do a quick scan
and remove all it finds.)
The next step is to download avast free
and allow it to do a bootscan on reboot and move ALL it finds to the chest.
After that (I don't know which anti-virus you are using) decide which one you want to keep on your PC. You can only run ONE while on-line, as 2 will have a conflict. Post back if you still have the problem
