Hoping on the whole of you are well. This is the time to present my avouchative speech.For making a digital Bangladesh, every citizen has to expert user of information process system and our authority has to computerize every sections of this country. But the major threat for victimisation a computer is computer computer virus. Thats why I have prepared my speech to inform my audience roughly it. Today I have prepared quartette special points for illustrate a virus. a) What is a Virus? b) What Viruses dont do? c) How does Virus spread? and, d) How to pr compositors case a Virus intrusion? a) What is a Vir us Computer viruses are weapons platformmes written by have in mind people.These virus programs are placed into a commonly used program so that program will run the attached virus program as it boots, therefore, it is said that the virus defiles the executable file or program. possible files include Macintosh system files such as system extensions, INITs and control panels and lotion programs such as word processing programs and spreadsheet programs. Viruses work the same styluss in windowpanes or DOS machines by sullying zip or exe files. A virus is inactive until you execute an infected program or application OR start your computer from a disk that has infected system files.in one case a virus is active, it loads into your computers memory and whitethorn save itself to your hard apparent movement or copies itself to applications or system files on disks you use. Some viruses are programmed specifically to damage the data on your computer by corrupting programs, deleting files, or even erasing your entire hard drive. Many viruses do nothing to a greater extent than display a message or make sounds / verbal comments at a certain time or a programming event after replicating themselves to be picked up by other users one way or another. Other viruses make your computers system behave erratically or crash frequently.Sadly many people who have problems or frequent crashes using their computers do not realize that they have a virus and go with the inconveniences. Though Viruses are really a threat for all computer users, it cannot be harmful in some points. b) What Viruses dont do Computer viruses cannot infect write protected disks or infect written documents. Viruses do not infect compressed files, unless the file was infected prior to the compression. Compressed files are programs or files with its common characters, etc. removed to take up less space on a disk. Viruses do not infect computer hardware, such as monitors or computer chips they only in fect software. In addition, Macintosh viruses do not infect DOS / Window computer software and vice versa. For example, the Melissa virus incident of of late 1998 and the ILOVEYOU virus of 2000 worked only on Window based machines and could not choke on Macintosh computers. One further note-> viruses do not ineluctably let you know they are present in your machine, even after being destructive. If your computer is not operating properly, it is a good practice session to check for viruses with a current virus checking program.Lacking of proper knowledge makes the virus more powerful and it helps to spread it in each file of a computer. c) How does Virus spread Viruses begin to work and spread when you start up the program or application of which the virus is present. For example, a word processing program that contains a virus will place the virus in memory every time the word processing program is run. Once in memory, one of a number of things can happen. The virus may be prog rammed to attach to other applications, disks or folders. It may infect a network if given the opportunity.Viruses behave in different ways. Some viruses chip active only when the application it is part of is running. Turn the computer rancid and the virus is inactive. Other viruses will operate every time you wrench on your computer after infecting a system file or network. We need to have proper knowledge, and stay safe from a virus. d) How to foil a Virus invasion Some tips to prevent virus invasion are given below I. Load only software from legitimate disks or CDs. Pirated or copied software is constantly a risk for a virus. II. Execute only programs of which you are familiar as to their origin.Programs sent by email should always be suspicious. III. Computer uploads and system configuration changes should always be performed by the person who is responsible for the computer. Password protection should be employed. IV. Check all shareware and free programs downloaded from on-line services with a virus checking program. V. Purchase a virus program that runs as you boot or work your computer. Up-date it frequently. Finally I hope everyone should be careful about viruses and enjoy a virus free computing. Thank you everyone. *Created by Alim Z Mir (optimist. emailprotected com)
