What is a virus?

A computer virus is the name given to a kind of program that appears on your computer without you intentionally downloading it.

An example of how this can happen by clicking onto links on an unsafe website.

These programs have a negative effect on your computer, often stopping it from working properly.

Because of this, it is important to make sure your computer is protected.

The best way to do this is to install an antivirus program which will help protect your computer from different kinds of threats, including spyware and ransomware.
