Hi Dorothy,
I'm afraid I am going to need to send you to your friends again to make another download. AVG has a removal tool and I'd like to try that. Get it from the following link:
http://www.avg.com/us-en/download-tools
First one on the list should be for you.
AVG Remover(32bit)
(avgremover.exe)
Try that and see if we can't get AVG out of there.
There is also another tool called Revo uninstaller. You may want to go ahead and download that too while you're there. I would try that next.

Question.....are you using IE to download? Do you have Firefox? Or another browser you could try?
