Show answer and explanation
Correct answers: A, B, D
Explanation
To effectively run a malware scan, it is important to ensure the antivirus software is up-to-date, disconnect the computer from the internet to prevent further threats, and perform a full system scan for comprehensive detection. Quick scans or interruptions (like restarting) may lead to incomplete results, leaving the system at risk.
- A. Correct.
Ensuring the antivirus software is updated is critical as it allows the software to detect the latest threats and malware signatures.
- B. Correct.
Disconnecting the computer from the internet during the scan prevents potential malware from downloading additional malicious files or communicating with external servers.
- C. Incorrect.
While a quick scan may save time, it often does not examine all areas of the system, potentially missing deeply embedded malware.
- D. Correct.
A full system scan is more thorough and checks all files and areas of the system, increasing the likelihood of identifying and removing malware.
- E. Incorrect.
Restarting the computer during the scan interrupts the process and could leave malware undetected or unresolved.
