What is a computer virus?A computer virus is a computer program that can copy itself and infect a computer without the permission or knowledge of the owner and can cause your PC to stop functioning or even result in data loss. A true virus can only spread from one computer to another when its host is taken to the target computer. Some methods of spreading a virus include a user sending it over a network or via e-mail, or carrying it on a removable medium such as a USB drive or CD.
The term “virus” is also commonly used to refer to other types of spyware or adware programs as well, although these do not have the reproductive ability.
Spyware – Does not create copies of themselves and spread, and does not result in data loss. Most common symptoms include a PC starting to run very slowly, or trouble when attempting to connect to the internet. These programs may invade your privacy and share your personal information across the internet.
Adware – This is usually loaded onto your PC when you install or download free software and can result in frequent unwanted advertising messages and pop ups.
