Computer virus information - A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. However, the term "virus" is commonly used, to refer to many different types of malware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by someone sending it as an email or over the Internet, or by carrying it on a removable device as a CD, or USB drive. Meanwhile viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer, often this by an email or a video downloaded from the internet.

Computer Trojans and worms - Viruses are sometimes confused with computer worms and Trojan horses. A worm can spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a file that appears harmless until executed. Computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. Today's viruses also take advantage of network services such as the internet, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware. Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply replicate themselves and perhaps make their presence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs and stop internet access. As a result, they often cause erratic behaviour and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.
