Many secure pages shown as insecure

Michael,

We apologize for the difficulties, it seems that you have installed two security programs on your device. We would highly recommend you to have any one security programs to avoid conflicts.

Please uninstall any one of the security programs and check if you are able to access websites without any issues. Please, feel free to let us know if you require any further assistance. Thank you.

After trying to log in several times on both computers my 2011 Packard Bell Easynote LJ71, recently returned from knowhow.com shows many secure sites as insecure, including avg.com and its support.
I cannot see where to upload a screenshot on here either.
