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?
Reboot the system normally and proceed to scan immediately on startup.
Boot the system into safe mode and then run a complete system scan.
Create a new user account with administrative privileges and run the scan from there.
Run a disk cleanup utility before scanning to remove any temporary files created by the malware.
