I'm using Windows 7 Pro

Hi,
I’m using Windows 7 Pro
And My Protection is “AVG AntiVirus FREE” i use with only/just for Windows..
Well which page should i use to uninstall the program or which Avg Clear removal setup?
Could you please provide the link, on this site?
Because i’m a beginner and i don’t want to do anything wrong, please i expect a detailed answer..
Thank You
