I'm new to tech support forums and must say I'm one step above a techno idiot. My computer is a Dell XPS R350 and is now 5 years old. Recently it seems the **** thing has been invaded by the most vile pornographic pop-ups and screens that lead you down a path wherein you have to turn the computer off to release yourself from their prison. I've tried deleting cookies and history but nothing works. They just keep coming back. What is happening and how can I rid myself of this plague. Do I need to go out and get a new computer? Is there anyway of perhaps stripping the hard drive clean and re-installing everything. Your help will be greatly appreciated.
