I have AVG security with Express install.July 2015. Now I am getting message "AVG Interface has stopped working.  This concerns me and makes me afraid to use internet without security.
I changed from Charter to ATT. in Dec. 2015 but have not experienced this problem until last week. I tried to communicate change to show my new email, but was unsuccessful.  Old email address was lowebc@charter.net.  New email address is balou1938@att.net.  Please help.

Hello Barbara,
To resolve the AVG interface issue, did you try uninstalling your AVG program using 'AVG Remover Tool' and then to reinstall? Thank you.
