IE recording recording text

Was hoping someone might be able to help with this one. The problem is basically when i use Internet Explorer (6.0) it is recording every keystroke i make meaning if i use a website and input my bank details etc. the next time i go back to that website all i have to do is click in the text box that i typed my details in and it will show a dropdown with every letter or number thats ever been typed in that box. An example of this is ticketmaster which i frequently use to buy tickets. i have used a couple of different cards to buy tickets on this site and any time i go to buy tickets and click in the box to enter details it shows every card number ive used. also when searching on yahoo etc it "saves" every search ive made and i am free to scroll down through a list of everything ive ever searched for in roughly the past 6 months. I have no idea how this problem came about as it never used to do this but as you can imagine its a bit unsecure as anyone that uses this computer will potentially have access to my bank details etc. Any help on this would be greatly appreciated.
