Discussion

Malicious code protection mechanisms include, but are not limited to, antivirus and malware detection software. To minimize potential negative impact to the organization that can be caused by malicious code, it is imperative that malicious code is identified and eradicated. This setting enables standard discovery for supported devices that have been onboarded.
