I haven't had any problems with mine I have trend security pro, It blocks everything and I have to get permission to allow anything to be installed or added. I've had trend for several years now. Best Buy had a special deal towards end of year and I only had to pay the shipping $4.99, no strings attached, nothing else to buy. Oldest Daughter got it also. You get 3 licenses, so then you can put it on 3 computers.
