Step-by-step explanation:
The question you're asking deals with the approaches a technician might use to remove a virus that interferes with antivirus software updates. The best option among the ones given is C. Safe mode. Booting a computer in safe mode starts it with a minimal set of drivers and services. This environment can prevent many types of malware from loading automatically, which may allow the technician to update the antivirus software or use it to remove the virus. Options A, B, and D offer different functionalities:
- Recovery console is a command-line interface for troubleshooting and repairing system issues.
- REGEDIT allows users to modify the Windows Registry, which can be risky unless you know exactly which registry keys to change.
- MSCONFIG is a system configuration utility that can be used to disable startup programs and services, potentially useful but not specifically for virus removal.
