I was reading a book that described an instance where a worker noticed that someone would run a security program that would scan his computer and the rest of his worked;he called this a because he later designed a program that allowed him to hop on this "żBus?" when it stopped to scan his computer.He would get on and of this bus when he pleased.


Is this possible to do and if so could somebody sort of push me in the right direction to write a program like this.


ps.What would be a good language to write this program in or is assembly the only choice due to its complex nature?Also, leave feedback.
