Should I install it? If I do could it make a mess of a system that is running well at present? I have heard a number of for's and against's and feel unsure and don't want to screw things up . I am running Norton 360, could that be a problem cpn
and as far as I can tell it made no difference at all in normal everyday usage. No benefits, no drawbacks and it did not crash my system. As 'wee eddie' says you are going to have to do it in the end, just make sure as with any major update that you have good recent back-ups.
