I need AVG installed ASAP!!!!!!

I just recovered my system and tried to install AVG 8.0 on my system. But it tells me that another antivirus is running and I think it's Norton Antivirus... But I can't access it to uninstall. I'm no computer wiz, but it doesn't show up in "program files" and when I tried to uninstall from the "Add or Remove Programs" window it tells me I can't do it that way, I have to login to Norton first??? So I searched files and folders and found it, I think I reinstalled it, and now my internet connection don't work!!!! But it still doesn't show up in my "program files". The point is I need Norton removed, and AVG 8.0 installed IMMEDIATELY! By the way... I have a wireless router and the internet connection on my laptop still works. I want you to walk me thru the process by talking thru skype...
