HOW TO CREATE VIRUS PROGRAM IN C LANGUAGE.
Hi ,every computer programing students have a dream to make a computer virus. Here we will study simple virus program created in c.(only for study pupose)You test the program in your own computer.There are several types of viruses with different functions.Some of which delete your computers' important files and folders,some change the configurations of your computer system,some dump your hard disc.There are some which can damage your RAM permenently.

THE HISTORY OF C PROGRAM
C is a general purpose computer programing language developed in 1972 by Dennis Richie at the bell telephone laboratories for use with UNIX operating system.Although c was developed for implementing system software.It is also widely used for developing portable application software.
C is the one of the most popular language for all time and there are very few computer architectures for which a C compiler does not exist.C has greatly influenced many other popular programming languages,most ...
