Explanation:
The correct answer is Norton because it is a dedicated, internationally recognized cybersecurity brand used to protect operating systems from digital threats.
Security Utilities: Norton Antivirus functions by actively scanning system files against a massive cloud database of known malware signatures, blocking suspicious scripts, and isolating malicious software before it compromises user data.
Continuous Monitoring: It provides real-time protection, scanning incoming web traffic, file downloads, and system processes to safeguard computing environments from malicious actors.
Incorrect Options:
Windows is incorrect because it is an overarching desktop operating system designed by Microsoft, not an independent antivirus utility software, though it includes a built-in security tool called Windows Defender.
Google is incorrect because it is a global multinational technology corporation famous for its search engine, cloud ecosystems, and web services rather than standalone antivirus endpoint products.
Firefox is incorrect because it is a free, open-source web browser developed by Mozilla used to navigate the internet rather than scan local files for viruses.
