Thanks for that but ive actually solved my problem a different way, i used system restore to go back in time to last week before the problems arose, besides ad-aware and zonalarm is there anyother software i should be using to find and destryo possible key loggers?

Great to hear your pc is up and running again.

Where did you get those first boot and login screens from? Maybe they where infected with something. To have a look for remaining problems please follow the instructions in the "Prework" link below in my sig, and post back with the 2 resulting log files to check.
