How vulnerable is LabTutor Server to viruses and how can I check its compatibility with my firewall settings before installation?

It is general good practice that all computers on a network have antivirus protection, especially if they are connected to the internet. It is strongly recommended that institutions set up a standard procedure for antivirus protection.

Some antivirus products can interfere with the normal operation and performance of LabTutor Server and LabTutor Client. This is because many antivirus products perform realtime scanning of web page content. Because LabTutor content is all served over HTTP this realtime scanning can add significant overhead to page load times, and in some cases, prevent LabTutor from functioning. If you experience performance issues with LabTutor it is recommended that you disable any realtime antivirus software scanning for HTTP, and that any antivirus Internet Explorer add-ons are disabled.


When LabTutor Server is installed, Windows Firewall is automatically configured to allow LabTutor Server to communicate with clients on ports 80 and 443. If you are having problems connecting to the server check that the incoming firewall exceptions are still in place in the Windows Firewall control panel item. If the incoming LabTutor Server exception is missing and there are no other exceptions to allow ports 80 and 443 though the firewall then you will need to manually add this exception to the firewall.

The LabTutor Server Installation Advisor can be used prior to installing LabTutor Server to check compatibility with your firewall settings.
