Problem I am having is that I can't get online anymore. I am pretty this has been caused by a virus. I keep getting a pop-up saying that Norton has stopped a virus and that my computer is protected. I guess that protected means I can no longer go online. When I try using Explorer to access MSN a page comes up saying invalid address. Will one of the virus removal discs you can buy @ Wall-Mart work at restoring my computer so I can buy and install some protection? What would be a good one to purchase?
