Answers
Answer:
A computer virus[1] is a type of computer program that, when executed, replicates itself by modifying other computer programs and inserting its own code.[2] When this replication succeeds, the affected areas are then said to be "infected" with a computer virus.[3][4]
Computer viruses cause billions of dollars' worth of economic damage each year,[5]
In 1989 The ADAPSO Software Industry Division published Dealing With Electronic Vandalism[6], in which they followed the risk of data loss by "the added risk of losing customer confidence."[7][8][9]
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.[10]
