AVG not starting

When I try either one of the AVG programs, I receive the same error message as above.
This also happens with other programs. Could there be a virus since my AVG is not working properly?

Betty,
I apologize for the inconvenience caused. To resolve the issue please follow the steps provided in this article : http://support.avg.com/SupportArticleView?urlname=How-to-troubleshoot-issues-after-upgrade-to-the-latest-AVG-antivirus-product

Note : Please run the AVG Clear first and then the AVG Remover

Once uninstalled, please install your AVG Ultimate from http://support.avg.com/SupportArticleView?urlname=Download-and-install-AVG-Ultimate

When I try to run AVG I receive the following message;
C:\Program Files (x86)\AVG\Framework\Common\avguix.exe

The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.

What do I do?
Thanks.
Betty
