Question

what is the second step in a good malware remediation procedure?
explore options for removing the malware from the system
contain the damage and infection by removing infected systems from the network
replace the infected device
temporarily shut down the network until the malware is removed from the infected device

Explanation:

A standard malware remediation procedure typically starts with detection, followed by containment to prevent spread. Containing damage by isolating infected systems from the network is the logical second step. Exploring removal options comes after containment, replacing devices is extreme and not a standard step, and shutting down the entire network is unnecessary compared to targeted isolation.

Answer:

Contain the damage and infection by removing infected systems from the network
