The Symantec Endpoint Protection client Auto-Protect Scan Actions settings must be explicitly configured at the top, Security Risks, level and not be overridden by the Parental Control sub-level.

Potentially Unwanted Programs (PUPs) include Spyware, Adware, Remote Administration Tools, Dialers, Password Crackers, Jokes, and Key Loggers. While PUPs do not typically have any infection capability on their own, they rely on malware or other attack mechanisms to be installed onto target hosts, after which they will collect and transfer data from the host to an external host and/or will be used as attach mechanisms. Configuring the antivirus software to attempt to delete the file first will prevent the infection from spreading.
