While attempting to remove malware from a system, a technician knows that it is a good practice to prevent the malware from persisting after the removal process. What is the BEST action the technician should take prior to executing malware scans and removal tools?
Perform a disk cleanup to free space and potentially remove temporary files where malware might reside.
Update all device drivers to ensure they are not compromised by the malware.
Disable System Restore to prevent the malware from potentially using restore points to re-infect the system.
Defragment the hard drive to enhance the effectiveness of the malware removal tools.
Before proceeding with malware scans and removal, it is important to disable System Restore. This step ensures that no malware can hide within the System Restore points, which can be used by the malware to re-infect the system after the cleaning process is complete. System Restore points can retain copies of the malware, therefore disabling System Restore helps to fully eradicate the threat. Performing a disk cleanup or defragmenting the hard drive, while beneficial in other contexts, does not address the risk of malware within restore points. Additionally, updating device drivers, although a maintenance best practice, will not assist in the malware removal process.
