Answer

The Symantec Antivirus Scan Engine works with Kerio MailServer on Windows 2000/2003. It does not install on non-server platforms.

Please Note: The Symantec Antivirus Scan Engine is not the same as Norton Corporate.

To install:

1. Download the trial version, or use your properly-licensed paid version.
2. Install the Scan Engine. If you have any trouble with the installation, refer to Symantec Enterprise Technical Support.
3. During the installation, choose the ICAP protocol, when asked.
4. After you have installed the Scan Engine, make sure that you have inserted your license using the Scan Engine administrator. If you are using a trial, the license will be e-mailed to you as a file.
5. Log into the Kerio Administration Console.
6. Go to Configuration → Content Filter → Antivirus
7. Check the box Use external antivirus and select "Symantec Antivirus Scan Engine 4.x/5.x"
8. Click on the button named "Options"
9. Edit Address and set its value to "IP of server running Symantec:1344" (Example:127.0.0.1:1344)
10. Edit "IgnoreStartupErrors" and change its value from 0 to 1.
11. Click "OK"
12. Click "Apply"

The Symantec Antivirus Scan Engine should now be working properly and scanning your incoming and outgoing email!
