Hello Tom,
We apologize for the inconvenience caused. To resolve the issue, we 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 your AVG Antivirus Free by clicking on http://files-download.avg.com/inst/mp/AVG_Antivirus_Free_692.exe .You can download other AVG programs from http://www.avg.com/ww-en/download .Thank you.

Tried installing AVG numerous times and keep receiving Error Code: 0xc0070643… Uninstalled all/any antivirus software from PC and am now vulnerable… Shall i just try Norton or other?

The issue has NOT been resolved.  Receiving same error code.  However, I thank you for assuming that it was resolved and trying to help.  I will have to try a different software.

Hello Tom,
We are glad to know that the issue has been resolved. Feel free to contact us again for any assistance. Thank you.

This worked for me!  Thanks so much!
