I'm new and don't know too much about computers but I recently bought a HP notebook and wireless router to enable my wife and I to use the desktop and notebook at the same time. It has worked out Ok until I decided to remove Norton Anti-virus that came installed on the notebook. I did this because the computer was very slow. (WE have AVG on the desktop) Tried this on the laptop but AVG must prevent networking. Any suggestions for an anti-virus that will be compatable with networked desktop and not slow down the notebook?
