My computer's CPU with Windows 10 is constantly running. It is hard to interrupt. It may take up to 30 seconds or longer to recognize new mouse clicks, select items from menus, etc. The modem shows constant activity. I have run Malewarebyte and McAfee scans which finds an occasional PUP error. I have tried to restore but no restore points exists early enough. It's almost like something has taken over the computer. Larry
