I am using Norton and have found its a little annoying..
Slows Pc a little it tends to let you know you have to restart for updates to take effect and a scan takes for ever! enough to go make a coffee ring someone, check the snail mail... come back and its still scanning.. totally annoying..

After subscription is up i think I'll be going to Trend Micro
what I should of done originally but once I had that Trojan found at the pc repair shop I became a impulse buyer...
