The 7 CompTIA Malware Removal Steps (A+ Core 2, Objective 2.6)
CompTIA A+ Core 2 objective 2.6 defines a specific, ordered process for removing malware from a Windows system. The order is not arbitrary — each step protects the next. You quarantine before you scan so the malware cannot spread, and you disable System Restore before scanning so it cannot hide in a restore point. This guide walks through all seven steps in order, explains why the sequence matters, and lets you check your understanding with free questions.
The 7 malware removal steps in order
Scenario: a Windows workstation shows pop-ups and runs slowly after a user clicked a suspicious email attachment.
1.Investigate and verify malware symptoms
Confirm the symptoms are actually malware before acting.
2.Quarantine infected systems
Isolate the machine from the network so the malware cannot spread.
3.Disable System Restore in Windows
Prevents the malware from hiding in or being restored from a restore point.
4.Remediate infected systems (update anti-malware, scan, and remove)
Update signatures, run a full scan, and remove threats.
5.Schedule scans and run updates
Set recurring scans and keep definitions current to catch new threats.
6.Enable System Restore and create a restore point
Re-enable Restore now that the system is clean and set a known-good point.
7.Educate the end user
Teach the user how to avoid the infection vector that caused this incident.
Why the order matters
Order matters because each step removes an escape route before the next one acts. You must quarantine before remediating so the malware cannot spread or re-infect, and you disable System Restore before scanning so the malware cannot hide in — or be restored from — a restore point. Only after the system is clean do you re-enable System Restore and educate the user to prevent recurrence. Skipping or reordering these steps can leave the infection in place or allow it to return, which is why CompTIA grades the exact sequence.
Memory tip
Remember the flow as "IQD-RSE-E": Investigate, Quarantine, Disable System Restore, then Remediate, Schedule scans, Enable System Restore, and Educate the user. The two "E" steps bookend the cleanup: enable restore, then educate.

Frequently asked questions
What is the CompTIA malware removal process?
It is the 7-step process defined in CompTIA A+ Core 2 objective 2.6 for safely removing malware from a Windows workstation. The steps run from investigating and verifying symptoms, through quarantining, disabling System Restore, scanning and remediating, scheduling updates, re-enabling System Restore, and finally educating the end user.
Why must quarantine happen before remediation?
Quarantining the infected system isolates it from the network so the malware cannot spread to other machines or re-infect the same machine from a network source. Only after it is isolated do you scan and remove the threat, which is why quarantine is step two and remediation is step four.
Why disable System Restore and then re-enable it?
You disable System Restore before scanning so malware cannot hide in or be restored from a restore point. After the system is clean, you re-enable System Restore and create a fresh restore point so the user has a known-good point to return to.
What does 'educate the end user' mean and why is it a step?
It means teaching the user how the infection happened and how to avoid it — for example not opening unexpected attachments or clicking suspicious links. CompTIA includes it as the final step because prevention stops recurrence, which is part of a complete remediation.
