Chapter 10 Review: Computer Virus

What is the primary characteristic of a computer virus?

• It enhances computer performance.

• It is a destructive software program.

• It protects data from corruption.

• It requires user interaction to spread.

According to the notes, all computer viruses are:

• naturally occurring.

• self-replicating and beneficial.

• man-made.

• designed to improve network security.

Which of the following is a common way for a computer virus to spread?

• Regular software updates.

• Using a firewall.

• Opening email attachments from unknown senders.

• Write-protected discs.

What can a computer virus potentially do to a computer system?

• Increase processing speed.

• Corrupt or delete data.

• Improve network connectivity.

• Enhance graphics rendering.

Some viruses become active only when:

• the computer is turned off.

• the infected program is executed.

• the anti-virus software is updated.

• a new user logs in.

Once active, a virus typically loads into the computer's:

• hard drive permanently.

• read-only memory (ROM).

• memory (RAM).

• central processing unit (CPU).

What is the main function of a computer virus's replication process?

• To repair damaged system files.

• To create backups of user data.

• To make copies of itself and spread.

• To optimize computer performance.

According to the analogy in the notes, a computer virus is like a biological virus because it:

• improves the host's functionality.

• destroys the cells of the body/information on the computer.

• is easily detected before causing harm.

• can operate independently without a host.

Which of the following cannot be infected by a computer virus, according to the notes?

• Executable files (.exe).

• Word documents (.docx).

• Write-protected discs (CD-ROMs).

• Compressed files (.zip).

What was the first computer virus created, as mentioned in the notes?

• Melissa.

• Brain.

• Creeper.

• Stoned.
