Option 1: Purge the cache.

  1. Unload the client.
  2. Delete the cache.dat file from the ..\Trend Micro\Client Server Security Agent\ directory.
  3. Reload the client.

  1. Log on to the WFBS console.
  2. Go to Updates > Manual.
  3. Make sure Smart Scan Pattern and Smart Scan Agent Pattern are updated.
  4. Perform updates from the WFBS agent to get the latest update from now on.
