Hi All I recently set up broadband on my sisters PC. Every time we connect to t'internet, we get pop-ups advising us to download/install/run various registry cleaners. Typically these popups would appear every ten minutes or so. I have now installed google toolbar to block the pop-ups, but the question is do we really need to install + run a registry cleaner, as there are no other problems or symptoms and the PC seems to be running fine. I am obviously very wary about running something which might prompt us to change a registry entry which may result in other problems. Any advise? Many thanks
