The correct answer is: B. Software
A computer virus is a type of malicious software that, when executed, replicates itself by modifying other computer programs and inserting its own code. When this replication succeeds, the affected programs are said to be “infected” with the virus.
Computer viruses can damage files, steal data, and even take control of a computer. They can spread through email attachments, infected websites, and removable media such as USB drives.
There are many different types of computer viruses, but they all share some common characteristics. They are all designed to replicate themselves, and they all have the potential to cause harm to computers.
To protect your computer from computer viruses, it is important to install antivirus software and keep it up to date. You should also be careful about what you open and download from the internet.

- A. Hardware: Hardware is the physical part of a computer, such as the CPU, memory, and hard drive. Computer viruses cannot infect hardware.
- B. Software: Software is the programs that run on a computer. Computer viruses are a type of software.
- C. Bacteria: Bacteria are tiny organisms that can cause disease. Computer viruses are not bacteria.
