A computer virus is a software program, script, or macro designed to infect, destroy, modify, or cause other problems with your computer or software programs. The user may protect him by using an anti-virus protection program. The anti-virus protection program designed to detect, protect, and clean any computer viruses. This is the most basic way to define a computer virus. There are tens of thousands of viruses out there with many more created on a daily basis. The protection program needs to updating on a constant basis. The computer needs updated with its running system, email and files in order to keep a completely safe PC. The normal use of any computer still puts the system at risk of being compromised by hackers unless you provide an anti-virus program for your protection along with a personal firewall.

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, adware, and spyware programs that do not have the reproductive ability. A true virus can only 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 USB drive. Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer
The term "computer virus" is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, trojans, most rootkits, spyware, dishonest adware, crimeware, and other malicious and unwanted software, including true viruses. Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda.
