Overview
Computer viruses, worms, and Trojan horses are malicious pieces of software that can cause considerable damage to your computer hardware, software, and information stored init. They can also slow down your PC, making it virtually unusable. This type of software falls into the category of malware (short for malicious software) since it is designed to harm or secretly access a computer system without the owner’s informed consent. Computer virus hoaxes are also quite common, but harmless in nature.
