1- After installing 11/17 NAV Update, all the locks in Norton AntiVirus application are no longer locking, they simply opens up immediately after locking them. This did not occur prior to installing this update.
2- After installing 11/17 NF Update, ALL the locks in Norton Firewall are no longer locking, they simply opens up immediately after locking them. Prior to installing this update, ONLY the lock in the NF Firewall Settings was not locking.
3- This issue remain after after installing 11/17 NF Update. Norton Firewall Application Blocking is still doing the same error by asking whether to Block an application which already have been added to Application Blocking and was set to Block. When I reply Yes, thereby the identical application end up appearing twice in the Application path settings list, and so on.
