The Symantec Endpoint Protection client Auto-Protect Scan Actions for Security Risks must be configured to Delete Risk as the first action upon detection.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-42662	DTASEP041	SV-55390r1_rule		Medium

Description
Malware may have infected a file that is necessary to the user. By configuring the antivirus software to first attempt to delete the infected file, availability to the file is not sacrificed. If a deleting attempt is not successful, however, quarantining the file is the only safe option so as to ensure the malware is not introduced onto the system or network.
