  A virus is a program that performs something other than it should perform.The procedure is as follows.First a virus keeps a label at the end of the file name.The code which the virus should perform exists here.Then it places a goto label after first line.after the execution of the code at the label it places a goto second line statement.the enduser wont have any idea that virus is executing.we can write a lot of viruses in c or c++.thats quite simple.

  I think assembly language is the best language in which you can write a virus.
  As this language can bypass the system (os) level security

  correct me if im wrong
  i think the person meant dat v "code a virus" n show it to him
  n not define the term virus
  
  
  a small virus in VB
  
  add a timer
  set the timer to 10msec
  enable the timer
  double click on the timer
  n then type "clipboard.clear"
  
  now make this as an exe file
  
  n then double click
  
  n now try to copy paste anythin from anywher
  
  it wont b done
  since the clipboard refershes every 10 msecs
  if ur faster then dat then.....
  then it will paste it or else.....
