Hello Carolyn,
We apologize for the inconvenience caused. To resolve the issue, I suggest you to remove AVG traces using remover tool( http://aa-download.avg.com/filedir/util/AVG_Remover.exe ). Please restart to complete the uninstalling process. After running AVG Remover, you may need to manually uninstall any remaining AVG applications and also 'search' for a folder "AVG Remover"(usually in 'C' drive) and please delete it manually. And then I request you to install AVG Antivirus Free based on your OS (32-bit or 64-bit) .To determine whether your OS is a 32-bit or 64-bit, please click on this link. http://support.microsoft.com/en-us/kb/827218

Hi,
I have used AVG free versions no problem in the past. I just got this computer but it won't let me install. I have removed the preinstalled McAffee software. How do I install the product? Thanks for any advice.
