We have Norton Anti-Virus Security on our home desk top computer, it has been running slow and locking up. So we took it in to our local computer shop, well $250.00 later, its fixed, full system flush, over 909 security alerts/virus alerts, with Norton. Running fine now, faster, not locking up, I know your going to blame it on me, but I ran system checks a lot with our Norton protection plan, which doesn't seem to be working for my wallet or computer. NOT A HAPPY CAMPER
