Do a disc cleanup
startprogramsaccessoriessystem toolsdisc cleanup.

Then to make sure:

startcontrol panelinternet options then hit delete cookies, then delete files, then clear history, then hit ok. It might take a few minutes for each one to process so be patient.

Then as you said, PROMISE TO NEVER DO IT AGAIN. :P Especially if you don't want to get caught being naughty.

to the above lol thanx peepz thankyou for ya help my cousin is readin and laughin but she going to do what you guys sed thankyou hope it works

what happens if you delete files?

IF she went into startcontrol panelinternet options and under the 'General' tab Temporary Internet files section ... delete cookies AND delete files.
'Delete files' ONLY deletes files in the Temp. Internet folder - nothing will be lost except incriminating evidence.
Also on the 'General' tab click on 'Clear History
Good Luck!!

PS - if her bro is really good he can still find evidence, but it takes some effort, and unless he is paranoid, he won't bother.
