Weird Problem Help!?

Question

Hey my home PC has 3 accounts. I got home this morning and went to click my account and I got some weird message unfortunately my contacts weren't in so I did read it. But it said something about contacts local administrator (I don't know who that is) and now I got some bad feeling it said something about local copy right infringement. But when I got into my account my settings were back to the default, and no other account is like that. All my files are gone, word, music everything.

Youve must have downloaded something from the net.

Go to start, all programs, accessories, system tools and choose system restore.

Set this back to a few days and let it boot up again.  Check to see if everything is back then.
