  1. Download the 64-bit Intelligent Updater (IU) Package for SMSMSE 7.9.x using either FTP or HTTPS.
  2. Navigate to <InstallDir>\SMSMSE\7.9\Server\definitions\Antivirus
  3. Determine the latest VirusDefs folder name (e.g. VirusDefs00000010)
  4. Create new folder named "Previous sequence number +1"  For above example: VirusDefs00000011.  (Note: This folder name is case sensitive)
