My dad was having problems with pop-ups, I tried to help him out by installing Ad-Aware and Mozilla. Ad-Aware installed and cleaned up the computer great. Mozilla installed but was "unable to connect to mozilla.org" I tried uninstalling and reinstalling it (also tried it with another version) but I was unable to connect to the internet? IE was still installed and I was able to acces with that, but not Mozilla. Is there anything I'm missing? He has XP.
