If scanning of your e-mail messages takes a long time and the Anti-Spam component is installed, we recommend that you disable the on-line checking option in Anti-Spam configuration or set it up to the lowest level. Please note that the level of your protection is not affected significantly.

• Open the AVG program.  
• Select Advanced Settings from the Tools menu.
• Navigate to the Anti-Spam branch and expand the settings.
• Click on the Performance option.
• Untick the Enable on-line checking option.

You can also change the Engine performance settings up to the lowest level on the same dialog as follows:

It is important to choose the correct e-mail plug-in to install during the AVG installation process. It depends on your e-mail client. If you use an email client for sending/receiving e-mails which has its own plug-in available in AVG, please install this specialized plug-in in preference:

• AVG MS Outlook Extension if you use Microsoft Outlook.
• AVG Plugin For The BAT! for The BAT! e-mail client.
• If you use any other program (Outlook Express, Incredimail, Mozilla etc.), please install the Personal E-mail Scanner plug-in.

In some unique cases, it is possible that your connection to the e-mail server will be blocked after installation of AVG. To find the cause of this issue, please try to disable AVG Firewall and E-mail Scanner. These two components can affect your e-mail client connection. To disable them, please refer to FAQ 2130.

In case disabling one or both of these components did help, please contact AVG Customer Services as described in FAQ 2216 for further assistance.

If you cannot download your e-mails after disabling the Firewall and E-mail Scanner, it is possible that there is some conflict between AVG and another application on your computer. In such case, please uninstall AVG temporarily (FAQ 1996) and contact our AVG Customer Services with as detailed description of the issue as possible.
