Save me.............

I have no idea what my dad press..
Anyway... I am using windows xp... now whenever I start or restart my comp... my home page will be changed to http://www.babe4us.com/ ...

I tried using adware... some online scans... but nothing is found...
I tried to run... msconfig... but nothing pop up... I press ctrl+Alt+Del
I found out that there are 2 invisible application with some funny wordings... I tried running the msconfig again... nothing comes out...
But the windows task manager application list... I can see 3 of the funny wording application... So... I think it got something to do with that... But I have no idea what to do... To get rid of those...
