• B. Worm
• C. Trojan
• D. None of these

Answer 1

Answer:

A. Virus

• Virus

  A computer virus is a malicious software program that loads onto your computer without your knowledge and executes against your wishes, typically by attaching itself to other clean files or programs and spreading as those files are opened or shared.

  Here is a quick breakdown of the related terms:

  • Virus: Requires a host program and user action (like opening an infected file) to spread.

  • Worm: A standalone malware program that replicates itself to spread from computer to computer independently (without needing a host file or user action).

  • Trojan: Disguises itself as legitimate software to trick users into downloading it voluntarily.
