Computer virus hold the ability to duplicate itself and infect all computers connected through a common network. It does so without permission or prior knowledge of the computer user. The term "virus" is also commonly used, although erroneously, to refer to various kinds of malware and adware programs.
A computer virus may adjust the copies, or the copies may change themselves, as occurs in a metamorphic virus. As such, a virus can only multiply itself when its host is taken to the uninfected computer, for example by a user sending it over network or the Web, or by carrying it on a removable mode such as a floppy disk, tape, CD, VCD or USB drive.
At times, computer viruses are confused with computer worms and Trojan horses. A worm can does not need to be transferred as part of a host, and a Trojan horse is a file that appears safe. Worms and Trojans may cause harm to system's hosted data, functional performance, or networking throughput, when executed.
A worm does not actually attempt to harm the system's hardware or software directly, while a Trojan's payload may be capable of almost any type of harm if executed. Some cannot be seen when the program is not running, but as soon as the infected code is run, the Trojan horse kicks in. This is because it is hard for people to find computer virus and other computer malware.
A majority of personal computers are connected to the Web as well as local area networks, facilitating the spread of malicious code. Computer viruses may take advantage of network services such as the World Wide Web, e-mail, Instant Messaging and file sharing systems to reproduce. Moreover, there are number of resources which use alternative terminology in which a computer virus is represented in any form of self-replicating malware.
Some computer malware is programmed to spoil the functionality of the entire machine by damaging programs, deleting files, and reformatting the hard disk. Other malware programs are not designed to do any damage, but simply spread themselves and make their presence known by presenting text, video, or audio messages. For an effective treatment of computer virus and alike malicious matter, you can consider availing the services of online computer support resources. They are 24x7 available and offer a economical and quality online pc support services.
