What Is Virus??

Life as we know it today would be handicapped without computers. From basic communication finances & even medical science, computers control just about everything that life in a modern society depends upon. In the ideal world, man would respect such power & work towards bettering it to progression as a civilization. Unfortunately, that ideal world does not exists which is why great breakthroughs are often followed by people who are hell-bent on bringing it all down. These people only see weakness of an innovation in technology and will go any lengths to exploit it, simply because they can. These are the people who create viruses.

A computer virus can be defined as an executable program that is capable of infecting other computer programs by modifying them to include a copy of itself just the way people can spread the common cold by being in contact with other people, a computer virus comes in contact with other program to 'infect' them. By infecting programs, the virus is capable of spreading through an entire network of computers, infecting every machine thats incapable of protecting itself. While doing so it could do a world of damage to your computer, which could cost you dear. The damage could consist of important files destroyed, corrupted data, slowing down of the infected computer, interrupted or unexpected closing of important programs, or it could be any or all of these; & chances are you wont realise that your computer is hit by a virus until its too much late.

ANTIVIRUS-

Viruses have grown in number and evolved in nature over the past decade. Before that, it was quite all right to have a basic & even outdated anti-virus program on your computer, which would scan floppies or CDs. Thats simple task would qualify as protection at the time but we now need active antivirus programs, constantly running, checking every file you download or execute.
