I tried several more times, but no luck.  However, I did not uninstall my AVG.  If I do that, can I get it back?

AVG is a resource hog. Here are some other free AV's. I would recommend MSE

Avast! Home Edition

Avira AntiVir Personal
Microsoft Security Essentials for Windows Vista\Windows 7 - 64 bit Download
Microsoft Security Essentials for Windows XP
Comodo Antivirus (Uncheck during installation "Install Comodo SafeSurf..", Make Comodo my default search provider" and "Make Comodo Search my homepage" if you choose this one)
PC Tools AntiVirus Free Edition

It is strongly recommended that you run only one antivirus program at a time. Having more than one antivirus program active in memory uses additional resources and can result in program conflicts and false virus alerts. If you choose to install more than one antivirus program on your computer, then only one of them should be active in memory at a time.
