I had AVG Internet Security 2011, and yes I'm a web designer and coder for Javascript, HTML, C++, Visual Basic, etc..
I know about forum intrusion and defacing websites, I've looked all through my website and so has my Web developer, maybe I'm overlooking something, if you guys find anything please tell me so I can delete it.
Thanks!
Oh and yes, I removed AVG Internet Security 2011 by uninstall programs via Control Panel > Uninstall a Program.
And thank you Pondus for the link.
