Virus – Vital Information Resources Under Seize.

Though they’re not a living thing like us, computers can get “sick” from viruses, too.

A computer virus is a computer program that can replicate itself and spread from one computer to another without your knowledge and runs against your wishes. All computer viruses are man-made. They insert themselves into host programs and propagate when the infected program gets executed.

In general usage, the term “computer virus” includes all forms of “malware“, or malicious software. Computer viruses currently cause billions of dollars’ worth of economic damage each year, due to causing system failure, wasting computer resources, corrupting data, increasing maintenance costs, etc. In response, free, open-source antivirus tools have been developed, and an industry of antivirus software has cropped up, selling or freely distributing virus protection to users of various operating systems. As of 2005, even though no currently existing antivirus software was able to uncover all computer viruses (especially new ones), computer security researchers are actively searching for new ways to enable antivirus solutions to more effectively detect emerging viruses, before they have already become widely distributed.
