Just Restore the system to a previous day, by Going to Start, all programs, Accessories, System Tools and then System restore. Click on it and select a previous day, on available restore points, when you did not have the problem. It is simple and secure. Your files and downloads will be intact. It will only remove the system files addition, which is responsible for your problems.
If it does not solve, then download malwarebytes from malwarebytes.com and scan ur computer and delete them by selecting all in the SHOw result box after the scan
The first solution is the best in these kind of unknown problems
