OK.............My only other suggestion is 2 run a System Recovery and bring back your PC 2 factory settings. This will give you a new slate. If you have any important files or folders, I suggest U back them up on a CD-R. This way U can install them back on your PC at a later date.
To run a System Recovery..............Shut down your PC manually, then start it up again. B4 anything loads tap the F10 button on your keyboard until U C the System Recovery partition open. When it does, click the Advance button at the bottom and follow the instructions from there on. When you've finished recovering your OS, here are a few recommendations: Mozilla Browser (Because of it's unique security), AVGFree v8 Anti-Virus, and Malwarebytes Anti-Malware. Keep them all up 2 date and U shouldn't have any more problems..............Good Luck!!!!!!!!!!!!
