Shared documents ate its self...

[Cuber]

It all started yesterday while I wasn't around, so I don't know if I'm getting the full story, but oh well.

My younger brother was here on this PC, he was listening to a mp3 from shared documents... next track goes to play, file not found.  Even the file he was listening to before is gone, and oh my god... everything in shared documents is gone!  All of it... I never even backed that stuff up.. Dunno if there's a way to get that back.. :/

But anyway, there's more.. after this over the phone I tell my sister to try rebooting... she does and well, windows wouldn't start up, I had to do a repair install to get it back again.
I'm to scared to even turn the PC off now.  I'm doing a virus scan with Prevx... wanted to try AVG as well but it keeps locking up on install plus a few other things are acting a bit strange to... like how I can't seem to view the system propertys, it takes a long time to load..

But seriously... I had 29GB remaining on my C drive before this, now it's 75GB... did it get so fed up with being over filled.  How rude of it...

Edit: I also appear to have no sound, this is turning out to be a bad day.
Edit2: Just had a Blue screen of death.. trying to load in safe mode, but the Administrator account is taking a very long time to open.

Try doing a search for your mp3's to see if you can locate any.

Can't.. they are gone... the space they took up has been freed up and it was more then just mp3s in there.. there was also videos and things.

Did you check your recycle bin?  If someone accidently deleted them you may be able to get them back with System Restore but before doing that the best route would be to eliminate the possibility that you are infected. If you're clean then System restore might get them back. You should download hijack this, run and post the log on your next post. I'm sure one of the malware experts can check it. The big question here is were they deleted or removed by some infection.

After restoring windows by having to do a recovery install, all old system restore points have gone. It sucks..

They also aren't in the recycle bin...
I'm starting to think I should save what remains (As my documents are fine) and reformat..

Sorry for the double post...
Update, installed SP3 again, seems better now... but I'm still a little on edge, spybot finds nothing, hm..

I have something of a personal experience to share.

I used to keep a lot of homework, music, ect in my shared folder with one of my other computers and I accidentally disconnected the shared folder, getting rid of everything inside.

I suspect something similar happened here...

How do you disconnect the shared folder?
It's on the same drive as everything else, so I don't know what you mean... also why would windows screw up after as well?
