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 or stealing personal information. 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.
