While the advertisements might be annoying, a more malicious behavior is exhibited by the BHO when it writes all visited URLs to a memory mapped section plasmatronWe believe that behavior-based approaches are capable of overcoming this drawback During development of our project we came across some interesting approaches that implement different kinds of taint analysis interface special care has to be taken when tainting network packets since only the contents but seldom the headers are interesting this is enforced in hardware ion source of this value - since the kernel does that internally The main distinguishing feature of the two modes is that only code in the kernel mode has access to physical resources like hard drive, network, or memory By creating component libraries a software vendor can use the same components for many different applications and has to manage only one instance of the library plasmatron This illustrates that the URL was copied at least once during the execution of the BHO and that the taint information is kept accurate during the whole process
