CompTIA A+ Core 2 (220-1102) — Question 128

Antivirus software indicates that a workstation is infected with ransomware that cannot be quarantined. Which of the following should be performed FIRST to prevent further damage to the host and other systems?

Answer options

Correct answer: A

Explanation

The correct first step is to power off the machine to stop the ransomware from executing further actions and spreading to other systems. Running a full antivirus scan or installing a different endpoint solution would not be effective until the machine is powered down. Removing the LAN card could be a secondary step but is not as immediate as turning off the machine.
