In some instances, Symantec Technical Support may recommend the use of an unsupported tool that automates the removal of corrupted SEP definitions. For details please see Using the "Rx4DefsSEP" utility at http://www.symantec.com/business/support/index?page=content&id=TECH93036&locale=en_US


Technical Information
How to disable Tamper Protection:
  • Open and log into the Symantec Endpoint Protection Manager console
  • Click the Clients view.
  • Select the appropriate group.
  • Under the Policies tab, in the "Settings" section, click General Settings.
  • Under the Tamper Protection tab, uncheck Protect Symantec security software from being tampered with or shut down.
  • Click OK.


IMPORTANT: Once definitions will be purged, the following popup message will appear:
"Virus definitions are missing on this computer. This computer will remain unprotected until definitions are downloaded from the network. Contact your system administrator for help updating your virus definitions."
This message will keep showing (after every smc -stop/smc -start or session opening), even when Symantec Endpoint Protection will receive/apply new set of definitions, until "Symantec Endpoint Protection" service is restarted. To avoid this, it is possible either:
 - to drop JDB file to update client then restart "Symantec Endpoint Protection" service
 - to use Rx4DefsSEP
 - to use a script which is checking Antivirus/Antispyware definition status and restart "Symantec Endpoint Protection" service if appropriate
NOTE: this behavior is as designed.
