Hoping all of you are well. This is the clock time to present my informative speech.For making a Digital Bangladesh, every citizen has to talented user of calculator and our authority has to calculatorize all sections of this country. But the major threat for using a reckoner is computer virus. Thats why I energise prepared my speech to inform my listening about it. Today I gravel prepared Four special points for illustrate a virus. a) What is a Virus? b) What Viruses dont do? c) How does Virus airing? and, d) How to stop a Virus intrusion? a) What is a Virus Computer viruses are programs written by mean p eople.These virus programs are located into a commonly used program so that program will run the attached virus program as it boots, therefore, it is said that the virus infects the executable file or program. Executable files include macintosh system files such as system extensions, INITs and control panels and practise programs such as word processing programs and spreadsheet programs. Viruses work the equivalent ways in windowpanes or DOS machines by infecting zip or exe files. A virus is electrostatic until you execute an infected program or application OR start your computer from a platter that has infected system files.Once a virus is active, it loads into your computers repositing and may save itself to your hard bear on 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 secret c ode more than display a message or make sounds / verbal comments at a received time or a programming event after replicating themselves to be picked up by separate users one way or a nonher. Other viruses make your computers system behave erratically or clash frequently.Sadly many people who have problems or frequent crashes using their computers do not realize that they have a virus and live 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 draw up 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 spot on a disk. Viruses do not infect computer hardware, such as monitors or computer chips they only infect software. In addition, Macintosh viruses do not infect DOS / Window computer software and vice versa. For example, the Melissa virus incident of late 1998 and the ILOVEYOU virus of 2000 worked only on Window based machines and could not operate on Macintosh computers. One further note-> viruses do not inescapably 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 to check for viruses with a current virus checking program.Lacking of proper association 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 exit of things can happen. The virus may be programmed to attach to other applications, disks or folders. It may infect a network if given the opportunity.Viruses behave in different ways. Some viruses stay active only when the application it is part of is running. Turn the computer off and the virus is inactive. Other viruses will operate every time you turn 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 prevent a Virus invasion Some tips to prevent virus invasion are given below I. Load only software from original disks or CDs. Pirated or copied software is endlessly a risk for a virus. II. Execute only programs of which you are acquainted(predicate) 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 set free programs downloaded from on-line services with a virus checking program. V. Purchase a virus progr am 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)
