avoiding drop downs

[derek]

              hi computer geeks.      i have a problem.
It is really embarassing to get the websites that i don't want them to be known by my  nephews and neices, just shows up on the drop down list on the side of the address bar. i don;t want to block these sites as well.
       so if anyone can tell me how to avoid these dropdown lists on the internet explorer address bar.!!
                                                        thanx ........
