AVG prevents download of ATT trouble shoot programs

Per ATT AVG is prevneting the download and usage of ATT Troubleshoot Plugin.

Even when we "shut off" the firewall and virus protection.

I have also tried uninstalling AVG and still ATT cannot repair my slow email issue.  Again they say it is an AVG issue.  
I have no issue with any other websites only ATT for my email and also Turbo Tax will not download.  
Again both companies say it is a AVG issue.

How can we resolve this???
