Den from everything i have ever read about Bullguard (quite a lot and it's all bad), i would get rid, there are a few decent alternatives (some free). I believe NOD32 or Kaspersky are good paid for options, or i quite like microsoft security essentials as i'm really cheap. I seem to remember Simon and Clive have a particular favourite (which i can't remember) but i' m sure they'll enlighten us.
