Windows 7 C Drive keeps filling up on it's own. Please help.

So about 4 days ago I noticed that my c drive had lost a few gigs, no big deal, but two days later suddenly my drive was in the red. I'm down to about 33gigs right now and it keeps dropping. I've run scans with Avira, Malwarebytes and Spybot but nothing has helped. Is it a virus or is it just some sort of system error? I haven't gone to any sites other than the ones I've always gone to for years now, nor have I clicked on any suspicious emails.

I would suggest running a program such as WinDirStat to find out where your space has gone!

Thank you, I used the program did a scan and found out realplayer was basically scanning and making a back up of all the media on my computer, found a 132gb fldrscn.out file in my realplayer folder. Thank you so much for your help.
