Problems with sending/receiving e-mails after AVG for Windows program update 7.0.322
If any problem appears with sending/receiving e-mails after AVG for Windows program update 7.0.322, it could possibly be caused by your computer firewall, especially ZoneAlarm or McAffee. Your firewall automatically blocks communication via AVG for Windows Personal e-mail scanner (AVG EMS) and does not ask if you would like to allow it. Because the AVG EMS component has been updated, your firewall does not recognize its updated content and behavior.
The problem is caused by your firewall, not by the AVG for Windows program. It typically appears with ZoneAlarm or McAffee firewalls installed. Some of the firewalls that either do not have such problems or that correctly detect the updated component include:
* AVG plus Firewall Edition
* Kerio
* Sygate
To solve the problem you have to remove AVG EMS from the configuration of your firewall, and then add it once again. For detailed instructions on how to configure the AVG for Windows program with different firewalls please refer to the Grisoft website, Downloads/Documentation section - Firewall Settings for AVG for Windows Workstation - Installation guide.
