AVG Blocking Secure websites that worked before update

Since the last update of the MAC Version of this software it has started blocking a secure https site that I use for paying invoices.  When I switch off the web shield it works fine so it is definitely AVG that is doing this and it comes up with a dialog proudly proclaiming that it has blocked this once available site.  When I look on these forums for help all I can find is instructions for configuring the windows version of the software or repairing AVG - again windows.  I would appreciate some help on the MAC version to get this sorted out.  Thanks

Hello David,

We will investigate and assist further on this matter.
We would like to know about the version of AVG Antivirus and Mac.
Provide the screenshot of both the versions here.
