Remediate and Update Anti-Malware Software for A+
Short answer
Before relying on a scan, ensure anti-malware solutions have up-to-date definitions and a recent engine. If the installed client cannot fully load or is compromised, use on-demand removal tools or bootable rescue media to scan offline. Quarantine actions preserve files while preventing execution; deletion should be a deliberate follow-up.
Why it appears on the exam
- Given a compromised AV client that is disabled by malware, select the correct remediation step (use on-demand removal tool or offline rescue media). - Identify whether a listed update is a definition update or an engine update based on a changelog excerpt.
Key concepts
Concept 1
Required terms
definition update: Virus/malware signature database updates that allow anti-malware tools to recognize known threats. engine update: Software update to the anti-malware scanning engine that can include heuristic improvements and bug fixes. quarantine (AV): Action by anti-malware software to isolate suspicious files so they cannot run while preserving them for possible analysis or restore. on-demand removal tool: Standalone utilities or bootable rescue media used to run scans and removal outside of the installed OS environment.
Example
Update the AV definitions prior to a full scan and confirm successful update.
Concept 2
How Remediate and Update Anti-Malware Software works
Before relying on a scan, ensure anti-malware solutions have up-to-date definitions and a recent engine. If the installed client cannot fully load or is compromised, use on-demand removal tools or bootable rescue media to scan offline. Quarantine actions preserve files while preventing execution; deletion should be a deliberate follow-up.
Example
Use a vendor's bootable rescue USB when the OS will not boot normally or the AV is disabled by malware.
Concept 3
Common confusion
- Confusing a definition update with an engine update; both are important but distinct. - Believing that updating definitions while the AV process is blocked by malware will always succeed; sometimes offline tools are necessary.
Example
Update the AV definitions prior to a full scan and confirm successful update.
Concept 4
Core 2 (220-1202) question cues
Given a compromised AV client that is disabled by malware, select the correct remediation step (use on-demand removal tool or offline rescue media); Identify whether a listed update is a definition update or an engine update based on a changelog excerpt.
Example
Use a vendor's bootable rescue USB when the OS will not boot normally or the AV is disabled by malware.
