What distinguishes a computer virus from other types of malware?
- A.A virus can spread over the network without user action
- B.A virus is always detected by antivirus software
- C.A virus requires a host file or program and user action to spread
- D.A virus only affects mobile devices
Why C is correct
A computer virus attaches itself to a legitimate file or program and requires user action (like opening the file or running the program) to activate and spread. This differentiates it from a worm, which can self-replicate and spread across networks without any user interaction.
