Hi, I recently installed AVG AS on my girlfriends laptop only to find the system running slow. She already had Norton installed on it. I uninstalled AVG only to find it still slow. I system restored it to find it better still slow, and now Norton wouldn't auto update. I dowloaded the Norton uninstaller , uninstalled it and reinstalled Norton again. It updates OK but the computer is still very slow to start up and the hard disk seems to take ages to settle down after startup, as well as running slow. I also during this time in stalled iTunes for her which has completely rearranged her music collection. I had to take all her music off ther hard drive a defrag 4 times to sort out the HD. It's still slow. any ideas ? She's well pissed off with me.
