I am running windows xp on a gateway desktop computer.My web browser of choice is Firefox. My computer will not connect to the internet unless i restart it. Even then it will not stay connected for more than 5 minutes or so tops.I connect to the internet through a wireless router. I have two laptops that connect just fine. I recently had a friend of mine over and he tried to delete Zone Alarm free edition. Currently I cannot find Zone Alarm on my computer but I know remnants of it are there as my friend did not properly uninstall it. Could this be why my computer will not stay connected to the internet? I have tried looking up information on uninstalling zone alarm but as I said I cannot open it or even find it! It is no longer listed in the add remove programs list either. Again I know parts of it are still on my computer. I have tried everything I can think of. Any help would be appreciated!
