Hello, I have noticed that many of you are using this AVG and was wondering if it is a good program or if you all use it because it is free. I use Norton Internet Security 2006 and it has some quirks that I am not fond of. However, it does alert me when something is trying to get access to my PC and I like that. Does AVG have some sort of protective means or does it wait to try to cure the virus once it allows it to get onto the PC? Finally, do you have to use Windows firewall or does AVG have one of its own? Take care, John
