Answer : 2. "It is a computer program"
Explanation :

a virus that spreads in a computer is a type of malicious computer program. Computer viruses are software programs designed to replicate themselves and spread from one computer to another. They can attach themselves to legitimate programs or documents, and when the infected program or document is executed, the virus activates and starts spreading to other files and systems. Viruses can cause various harmful effects, such as corrupting or deleting files, stealing sensitive information, or disrupting computer operations. Antivirus software and best practices, such as avoiding suspicious downloads and email attachments, are used to protect computers from these malicious programs.
