Turn off the antivirus and try scanning again Do not take any action as the antivirus is possibly functioning properly Update the antivirus signatures and perform a full system scan Uninstall the antivirus and reinstall an older version

Correct Answer: Update the antivirus signatures and perform a full system scan

Updating the antivirus signatures and performing a full system scan ensures that the latest malware definitions are used and provides a better chance of detecting the malicious file.

Question 2

A user's computer has been infected with ransomware. What is the most appropriate immediate action the user should take to mitigate the impact?

Delete all affected files to prevent further encryption Pay the ransom to obtain the decryption key Restart the computer in Safe Mode and try to decrypt the files Disconnect the computer from the network and contact the IT department

Correct Answer: Disconnect the computer from the network and contact the IT department

Disconnecting the computer from the network and contacting the IT department helps prevent the ransomware from spreading to other systems and allows experts to work on a solution.

Question 3

A company has recently had a malware attack. After cleaning and securing the systems, the IT department wants to implement an antivirus and antimalware software. Which type of solution would be the most effective?

Comprehensive solution that includes signature-based and behavior-based detection Heuristic-based solution only Behavior-based solution only Signature-based solution only

Correct Answer: Comprehensive solution that includes signature-based and behavior-based detection

A comprehensive antivirus and antimalware solution that combines signature-based and behavior-based detection provides the best protection as it can detect known malware based on signatures and unknown malware based on suspicious behavior.
