CLASS VII Holiday Assignment Reading Skill Computer Viruses A computer virus is a small programme that is written to copy itself into other computer files. It gets executed automatically whenever the infected file is used and destroys data and other programmes residing in the computer s storage media. (floppy-disks, hard disks, CD s, pen drives, etc). A computer virus normally attaches itself to other computer programmes and becomes part of them. A virus programme is written in such a way that it situates itself into the computer s memory and gets executed automatically. Then it copies the virus instructions into all the other programmes that are being executed on that computer. This activity or process, in computer terms, is called infecting the system and the files. The infection can then spread to other computers through floppy disks, memory storage devices, computer networks, emails, the Internet and other online systems. Some viruses are harmless as they display jokes or messages on the screen without damaging the system. On the other hand, viruses can cause crashes (destroying data and programmes) and even a large computer system within a few minutes. 1. Answer these questions. a. What is a computer virus? b.
