Any supported external antivirus application that you intend to use must be installed first. The McAfee antivirus application is integrated into WinRoute and you will need a special license to run it.

Select an appropriate antivirus application in the Antivirus tab under Configuration / Content Filtering / Antivirus and choose protocols that will be scanned. All executables and Microsoft Office files are scanned by default.

The HTTP, FTP scanning and Email scanning tabs enable detailed configuration of scanning of individual protocols. Usually, the default settings are convenient.
