im currently using eset smart security 5 ..my friends said that it is not a good one so i got a doubt in my mind,decided to choose a best internet security available on the market ..my eset's scan speeds are very fast ..it did not slow down my pc very much .i installed kaspersky internet security by removing eset ..the computer was slowed down like a hell..is there any internet security that will not slow down the system very much and offer best protection for windows 7..
