Zorluk: KolayMalware Detection, Removal, and Prevention

An IT support specialist is responding to a reported malware infection on a company workstation. Arrange the following actions in the correct sequence according to the standard CompTIA malware removal process, starting with the earliest step and ending with the final step.

  1. 1Disconnect the infected workstation from the corporate network and isolate all removable media.
  2. 2Turn off System Restore in Windows settings to remove unverified system restore points.
  3. 3Update anti-malware definition files and perform a thorough system scan to clean infected files.
  4. 4Re-enable System Restore and create a clean baseline restore point.
  5. 5Conduct security awareness training with the primary user of the workstation.

Cevap

The correct sequence follows the CompTIA 7-step remediation process: 1. Disconnect the infected workstation from the network (Quarantine), 2. Turn off System Restore (Disable System Restore), 3. Update anti-malware definitions and perform a thorough scan (Remediate), 4. Re-enable System Restore and create a clean baseline restore point (Enable System Restore), and 5. Conduct security awareness training (Educate the user).
The standard CompTIA 7-step malware removal workflow mandates the sequence: Identify -> Quarantine -> Disable System Restore -> Remediate (Update & Scan) -> Schedule Updates & Scan -> Enable System Restore & Create Restore Point -> Educate End User. Isolating the system comes first to contain the threat. Disabling System Restore removes corrupted backups. Updating definitions and scanning removes the threat. Re-enabling System Restore creates a verified safe baseline. Finally, user education prevents recurrence.

Adım Adım Çözüm

1
Isolate the infected endpoint from the network infrastructure.
The machine is quarantined to prevent lateral movement of the malware.
Quarantining the infected system immediately follows identifying the malware symptoms.
2
Disable the Windows System Restore feature.
All existing restore points (which may contain malware copies) are deleted.
Disabling System Restore prevents malware from preserving itself in restore archives.
3
Update malware signatures and run remediation tools.
The active malware infection is detected and eradicated.
Remediation requires updated signatures and scanning, typically performed in Safe Mode.
4
Turn System Restore back on and create a new restore point.
System Protection is active again with a known-good clean state image.
System Restore should only be re-enabled after verifying the system is completely clean.
5
Provide end-user training on safe computing practices.
The user is educated on recognizing phishing, rogue downloads, and social engineering.
Educating the user is the final step of the malware removal framework.
