A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD or flash drive.
The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, even those that do not have the reproductive ability. Malware includes computer viruses, computer worms, trojan horses, rootkits, spyware dishonest adware and other and other malicious and unwanted software, including true viruses.
Viruses are sometimes confused with worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan horse is a program that appears harmless but hides malicious functions. Worms and Trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.
Hoaxes are not computer viruses at all but may advise a user to delete or modify a file that your computer needs to operate correctly.
These pests show themselves in a number of ways. Your computer may reboot itself again and again, may not start up at all or may start and then display a blue screen, sometimes called the “blue screen of death”. The computer may slow down to a crawl. You may get messages that pop up warning you of non-existent threats.
