An employee reports that their PC is behaving erratically with frequent popup ads and programs starting automatically, which they suspect is due to malware. You decide to perform a malware scan. Before running your anti-malware software, which step is essential to improve the chances of detection and removal of the malware?
Run a disk cleanup utility before scanning to remove any temporary files created by the malware.
Create a new user account with administrative privileges and run the scan from there.
Boot the system into safe mode and then run a complete system scan.
Reboot the system normally and proceed to scan immediately on startup.
