What is the primary difference between a virus and a worm in cybersecurity?

• A. A virus requires a host file to spread
• B. A worm is always more dangerous than a virus
• C. A virus can self-replicate without a host file
• D. A worm requires a host file to replicate

Answer: (A)

The primary difference between a virus and a worm in cybersecurity is that a virus requires a host file to spread. A virus attaches itself to an executable file or program, and it relies on users to run the infected file in order to propagate. This means that the virus cannot spread on its own; it needs human intervention for its distribution. In contrast, worms are capable of replicating themselves independently over networks without the need for a host file. They can exploit vulnerabilities in network protocols or operating systems to spread autonomously from one computer to another. This makes worms particularly dangerous, as they can infect many systems quickly without any direct user action. Understanding this distinction helps in recognizing how different types of malware operate and the methods required for their prevention and removal.
