A technician follows the proper procedure for malware removal on an infected computer. However, the technician is unable to remove all the malware and decides to reload the OS. Which of the following should the technician select?

Rationale

Clean install.

A clean install of the operating system ensures that all existing files, including any remnants of malware, are completely removed from the computer. This method provides a fresh start, eliminating the risk of re-infection and allowing the system to operate smoothly without the interference of previous malware.

A (Version upgrade) YOUR ANSWER

A version upgrade typically retains existing files and settings while updating the OS to a newer version. This approach does not guarantee the removal of malware, as any infected files could remain intact, posing a risk of continued infection.

B (System restore) YOUR ANSWER

System restore reverts the computer's state to a previous point in time, which may not effectively remove malware that has infiltrated the system after the restore point was created. If the malware was present before the selected restore point, it would still be on the system, failing to resolve the infection issue.

C (OS repair) YOUR ANSWER

OS repair attempts to fix issues within the current operating system without erasing user data or installed applications. However, similar to a version upgrade, it may not fully eliminate malware, as it does not involve a complete removal of all files and settings, potentially leaving remnants of the infection.

D (Clean install) CORRECT

A clean install is the most effective method to ensure that all malware is removed, as it wipes the hard drive clean and reinstalls the operating system from scratch. This process guarantees that any persistent malware is eradicated, providing a secure and stable environment for the user.

Conclusion

In the context of malware removal, a clean install is the optimal choice when other methods fail to eliminate the infection. It effectively removes all traces of malware, ensuring that the system is free from any potential threats. While other options may address certain issues, they do not provide the comprehensive solution needed to guarantee a malware-free environment.
