What internet security do you all use? That time of year again my Norton has just a few days remaining before I need to renew for the year. Was wondering what you guys find best to use as thinking of swapping to a different one? I find Norton brilliant at protecting against threats and monitoring stuff just it doesn't half slow the computer down and rob its performance when it is doing it's daily scans.. So might swap to another one that hopefully doesn't rob as much performance as Norton?
