I run XP and Firefox. Abourt two weeks ago when I access a security type site(like internet brokerage) the screen frezzes up and its difficult to end the program. Not sure if the prob. is XP or firefox? The brokerage site suggested I have temp files full?? I thought all those had been deleted when I close Firefox every time. Any suggestions? I am a novice PC user. Thanks for any advice. PS I have been using adaware and spybot regularly the last few years so I doubt its a malware prob.
