After a security event, a technician removes malware from an affected laptop and disconnects the laptop from the network. Which of the following should the technician do to prevent the operating system from automatically returning to an infected state?

Enabling System Restore could potentially reinstate the malware if a restore point created before the infection exists. This would undermine the technician's efforts to remove the malware, as the operating system could revert to a compromised state.

While enabling antivirus is a valuable step in maintaining security, it does not specifically prevent the operating system from reverting to an infected state. Antivirus software works to detect and remove threats but cannot stop the restoration of infected files from a previous state unless System Restore is disabled.

Disabling antivirus would leave the system vulnerable to threats, including any remnants of malware that may still be present. This choice would contradict the objective of ensuring a secure and malware-free environment after the initial removal.

Educating the user is important for long-term security awareness, but it does not provide an immediate technical solution to prevent the operating system from returning to an infected state. User education should complement technical measures, not replace them.
