Zorluk: OrtaMalware Symptoms and Standard Removal Procedures

A desktop support technician at a municipal water utility is responding to a Windows 11 workstation that was infected with malware via a malicious email attachment. The technician has already identified and confirmed the malware infection symptoms. In what order should the technician execute the following remediation steps according to the standard CompTIA 7-step malware removal procedure?

  1. 1Disconnect the workstation from the municipal network and disable all wireless adapters.
  2. 2Disable Windows System Restore on the infected workstation.
  3. 3Update anti-malware signatures and execute a full system scan in an isolated environment.
  4. 4Re-enable Windows System Restore and generate a clean system restore point.
  5. 5Conduct end-user training on recognizing social engineering and phishing attachments.

Cevap

The correct order follows CompTIA's 7-step malware removal process: first quarantine the system by disconnecting network connections, next disable System Restore, then remediate the system by updating signatures and scanning, followed by re-enabling System Restore to create a clean restore point, and finally educating the end user.
The standard CompTIA 7-step malware remediation process specifies the following sequence: 1) Identify malware symptoms, 2) Quarantine infected systems, 3) Disable System Restore, 4) Remediate infected systems (update definitions and scan), 5) Schedule scans and run updates, 6) Enable System Restore and create a restore point, and 7) Educate the end user. Disconnecting network interfaces isolates the device first, followed by turning off System Restore, running updated anti-malware scans, re-enabling System Restore to build a clean baseline, and concluding with user education.

Adım Adım Çözüm

1
Quarantine the infected system.
Network adapters are disconnected, preventing the malware from spreading across the local municipal network.
CompTIA Step 2 requires isolating the infected host immediately following identification.
2
Disable System Restore.
Previous restore points containing latent malware files are purged and new restore point creation is paused.
CompTIA Step 3 ensures that malware cannot persist or re-infect the system via Windows System Restore.
3
Remediate the system.
Anti-malware definitions are updated and a comprehensive scan cleans or quarantines infected files.
CompTIA Step 4 involves active malware removal using updated tools.
4
Enable System Restore and create a restore point.
System protection is restored with a verified malware-free baseline.
CompTIA Step 6 re-establishes OS recovery capabilities once the system is verified clean.
5
Educate the end user.
The user is trained to recognize social engineering tactics and suspicious attachments.
CompTIA Step 7 concludes the remediation process by addressing human risk factors.
