Final answer:
To remove stubborn malware, a technician should boot the system into Safe Mode, use updated antivirus and antimalware software, and consider advanced tools for persistent malware. Manual removal or a full system reset may be necessary for particularly tenacious infections.
Step-by-step explanation:
To remove stubborn malware from a Windows computer, a technician can take several steps. Firstly, it is recommended to boot the system into Safe Mode to prevent the malware from loading at startup. This can be done by restarting the computer and pressing the F8 key (or following the appropriate instructions for Windows 10 or later versions) before the Windows logo appears.
Once in Safe Mode, the use of reputable antivirus and antimalware software can help in detecting and removing the malware. It's crucial to update the software before scanning to ensure the latest malware definitions are used.
If malware persists after these steps, the technician might need to utilize more advanced tools such as bootable antivirus disks or malware removal tools specifically designed for persistent threats. Additionally, manual removal might be necessary, which involves identifying and deleting malicious files and registry entries associated with the malware.
As a last resort, if the malware cannot be removed and it compromises system integrity, a full system reset or reinstalling the operating system may be necessary. It is important to back up important files before taking this step, to avoid data loss.
