What Is A Pc OR Computer Virus - Definition, Is It The Same Like The Virus From Which We Get Ill - Computers - Security

Computer viruses are software programs written in a way to attack and steal information from the computers and laptops worldwide. These are meant for only attacking users computer or we can say targeted users computer. The most common computer viruses are viruses, worms, Trojan horses, and email viruses Though each computer viruses has its own features and problem causing agents they basically work in the same way. Almost a majority of them spread from computer to computer and there are basically three separate major groups of computer viruses which are boot sector viruses, file infectors, and macro viruses.Virus Definitions, also known as Virus Signatures, are the individual identifiers that are used by anti-virus software to identify and neutralize virus software which attempts to infiltrate your PC system. When fighting the enemy - it helps to know what and who they are! VIruses are actually computer Programs written by Computer Programmers, to whom we called Programmer s. But these programs are meant to act notoriously. These programs are not usefull. They are developd with a view to attack the computers worldwide. By doing this the owners of these Viruses/Trojans/Worms/Spywares etc. try to steal usefull data found on the computers globally. In different cases the purpose and the mode of attack by these notorious programs are different. These programs are so written that we even don't get notice of it when the invasion took place. But when we get to know about the problem many a times It's too late. Viruses are usually unique, or, if similar, can be variants of one another. Whatever form they take, and however they work, they are designed with one, and only one thing in mind - the manipulation of your machine to serve the purposes of the person writing the virus programming code.The purpose could be mischief - to some people it is highly amusing to destroy something which does not belong to them. To others, it could be a means of cheap adv ertising, such as in virus spam mail, where they piggy back off your expense account by getting your computer to send out spam mail on their behalf. Yet others have much more sinister aims, and attempt to infiltrate your system for the purpose of obtaining personal details such as banking account numbers, personal ID data, for purposes of criminal behavior, identity theft, or fraudulent transactions.Types Of Viruses:1. Viruses2. E-mail Viruses3. Trojan Horses4. WormsViruses generally work behind the scenes - they arrive as hidden code on the backs of innocent looking emails, links which you are encouraged to click on in websites which you perceive to be safe (these are known as Trojans), and as hidden code in the form of downloadable programmes such as games (malware). Spyware records what you look at, where you go when you surf, and sometimes your keystrokes, which endangers your security. They spread like worms, via emails or file sharing, and send copies of themselves to others who you normally communicate with or have received emails from (all those In you're address book). Sometimes viruses can work behind the scenes for long periods of time without the user even being aware of them. They may sap the processor, or they may just dance along in the background causing very little disturbance at all. It pays to be aware of viruses and how they can negatively impact on your personal computer use, and in particular, your personal life. Question - Can Viruses Infect Storage Devices Like Discs?Answer - The answer to this question is - Computer viruses can not infect disks whichh are write protected or infect written documents. Viruses also do not infect compressed files, but the infection can be before compressing the file. The viruses also do not infect cmputer hardware devices like your Monitor, Keyboard, Mouse, computer chips etc. It can only infect the computers software. Viruses also are not able to invade or infect DOS OPERATING SYSTEMS.Mini mize the risk of identity theft and fraud by installing and maintaining anti-virus, anti-malware and anti-spyware software on your personal computer. It doesn't have to cost you much - plenty of effective freeware and shareware anti-virus programs exist and are available for you to download and use. Some recommendations include MS Security Essentials, AVG - Free Edition, and Malware Bytes.
