Configure antivirus applications.
Many antivirus applications install "script scanning" components to ensure that malicious
script-based malicious software cannot be executed. In order to display web page
content, we load a script host in our web server process. When processing web pages and
requests, we must wait for the antivirus application to scan the contents before we can
deliver the page to the requesting browser. Consider disabling the scanning of our script
engine component. For more information, contact your antivirus software vendor.
