I used to have AVG but it has alot of problems with its detection and removal of things, i wouldnt rate it myself, I once removed something one day done a second check to make sure it had gone and it had, also not been on the internet, disconnected it and the next day ran AVG and it was back, I run spyware blaster along side spybot and find it works pretty well, never had that many problems in the three years ive had this laptop
