To change the communication protocol to HTTPS:

1. Make a copy of ofcscan.ini (C:\Program files (x86)\Trend Micro\Officescan\PCCSRV).
2. Stop the OfficeScan Primary Service.
3. Make these changes:

   [Global Setting]
   ASE = 1

4. Save and exit the file.
5. Restart the OfficeScan Primary Service.
6. Log in to the OfficeScan console and click on Agents > Global Agent Settings.
7. Click Save even if there were no changes.
8. After a few minutes, check ofcscan.ini again to see if the ASE value changed. Make sure that it's set to "1".
9. Unload and reload the OfficeScan agent on your machine. You can confirm on your machine's registry:
   • For x64 platform: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\PC-cillinNTCorp\CurrentVersion\]
   • For x86 platform: [HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\]

   Key: ASE
   Type: REG_DWORD
   Value: 1

   Any agents that get this configuration change will unload and reload the OfficeScan agent automatically.
