A computer has been infected with malware. Despite several attempts to remove the malware, the issue persists. Which of the following actions should the technician take next? (Choose two.)

Reimaging the computer involves completely wiping the existing operating system and reinstalling it from scratch, which is the most definitive way to ensure all malware is removed when other attempts have failed.

Restoring from a last known-good backup is an option, but reimaging offers a more certain path to a clean state when removal attempts have already failed and the exact infection time or backup integrity is uncertain.

Removing the computer from the network is crucial to prevent the malware from spreading to other systems or exfiltrating data, isolating the threat while remediation efforts are underway.

Putting the computer in safe mode is a common initial step for malware removal, but the question states 'several attempts to remove the malware' have already failed, implying safe mode was likely already tried or ineffective.

Verifying file consistency is a troubleshooting step, but it doesn't directly remove malware; malware can masquerade as legitimate files or corrupt system files, making simple consistency checks insufficient for eradication.

Enabling the system firewall is a preventative measure or a component of ongoing security, but it does not remove existing malware that has already bypassed initial defenses.
