Anti$-$malware software utilizes different methods to detect malware. One of these methods is scanning. Which of the following best describes scanning?

answer

Scanning uses live system monitoring to detect malware immediately. This technique utilizes a database that needs to be updated regularly. Scanning is the quickest way to catch malware programs.

Scanning aids in detecting new or unknown malware that is based on another known malware. Every malware has a fingerprint, or signature. If a piece of code contains similar code, the scan should mark it as malware and alert the user.

Scanning establishes a baseline and keeps an eye on any system changes that shouldn't happen. The program will alert the user that there is possible malware on the system.

Scanning is when the anti$-$malware software opens a virtual environment to mimic CPU and RAM activity. Malware code is executed in this environment instead of the physical processor.
