  - db1*
  - db2*
  - attr*
  Delete other files that has the "db" prefix (e.g. db1-shm, db1-wal, db2-shm,db2-wal, etc.).
4. Get a copy of the db1, db2 and attr files:
  - Copy from: ..\Trend Micro\Security Server\PCCSRV\wss\spsc\support\
  - Place to: ..\Trend Micro\Security Server\PCCSRV\wss\spsc\conf\
5. Open a command prompt with administrator privilege, then change the directory to Trend Micro\Security Server\PCCSRV\WSS\spsc\bin.
6. Execute the following commands:
  - activeindex -i
  - attributetool -i
7. Make sure there is at least 5GB free disk space.
8. Start the Trend Micro Security Server Master Service on the Windows Services Console (Services.msc).
