Install or reinstall what?
Restore as in System Restore or as in Factory Restore? How?
Reboot is simply shutting down and restarting your computer.
Please explain exactly what you are trying and why.
Have you tried updating your antivirus program and scanning?
Try restarting in Safe Mode with Networking, download, install, update, and run Malwarebytes. Remove all it finds.
If you cannot install Malwarebytes this way, try System Restore from Safe Mode and choose a restore point well before you noticed any problems. When system restore completes, try Malwarebytes again.
You have to be a little bit crazy to keep you from going insane.
