2.4 Summarize types of malware and tools/methods for detection, removal, and prevention.
Objective 2.4 sits in Security, which carries 28% of the A+ Core 2 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Which capability does Microsoft Defender Antivirus use to catch malware that does not match any predefined pattern, such as fileless attacks that exploit legitimate processes?
The concept
Modern antivirus engines supplement signature matching with behavior-based detection to catch malware that has no known file signature.
Why this answer
Anomaly detection monitors process creation events and internet downloads, letting Defender Antivirus flag malware that doesn't fit a predefined pattern, including fileless attacks.
- Correct: this is the feature explicitly described for catching malware with no predefined pattern.
- BSignature-based matching was the older static model Defender moved away from in 2015; it cannot catch unknown patterns.
- CIPsec authentication is a Windows Firewall feature for verifying connecting devices, not a malware detection method.
- DNetwork Location Awareness assigns firewall profiles based on network type; it does not detect malware behavior.
Now you: objective 2.4 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 2
A traveler connects a laptop to open Wi-Fi at a hotel lobby. To reduce exposure to malware attempting unsolicited inbound connections, which Windows Firewall network profile is applied automatically?
Sample question 2 of 2
A technician disables Windows Firewall on a laptop so a peer-to-peer file-sharing tool works without configuring exceptions. Beyond losing basic traffic filtering, which specific security benefit is lost as a direct result?
