By default, the Scheduled Scan setting is disabled on SA. The procedure below is for standalone clients, meaning those that do not have a connection to the WFBS server.

To enable it:

1. Open the Registry Editor (regedit.exe).
    

   Always back up the whole registry before making any modifications. Incorrect changes to the registry can cause serious system problems.

    
2. Look for the following registry hive:

   HKEY_LOCAL_MACHINE\SOFTWARE\TrendMicro\PC-cillinNTCorp\CurrentVersion\Prescheduled Scan Configuration\Allowcfg

3. Set the value of "Key Allowcfg" to "1", and then close the registry.
4. Open the Security Agent from the system tray, then click Scan.

   You can now configure the Scheduled Scan settings.
