I bought Trend Mirco for the first time and it would make my computer freeze and i would have to manually shut it down. My computer worked good without the program, i installed since my Norton expired. I talked to them a zillion times with no results they didn't know why the program made my computer slow and freeze. Than after a little while my computer completely crashed. and i had to take it to repair. I cant take the software back...and i exchanged it ..now i don't know what to do with it...should i re installed it or would it do the same thing? They repaired my computer and it works great without the anti-virus but im kinda scared to not have it.
