Antivirus

Mmmm...sitting for hours in front of my computer today make me feel a little boring. My laptop this morning have a report that my Norton antivirus has expired...it means that I need to buy a new one and installed it.

But I have confused to choose which antivirus is good for me , I asked my friend and she told me a new name that I don't know exactly...she said it is good for her and it makes me to think about it for hours.At last I try to installed AVG antivirus..it have a free download so I think may be it is good for me and I should try it too.
