Disk Space Disappearing on OS Partition

Hey guys, I've been having a problem for a few months now regarding the amount of free space I have on my OS Partition (I'm running 7). The partition has a total of 20 gigs and is currently using 18 of it. Now, the problem is that a while back I had more than 2 gigs free, probably somewhere around 4 or 5. However, one day it suddenly dropped significantly, and started to do so sporadically for the next few days. I then went through and removed any unnecessary programs and temp files and system restore points and that only freed up about a gig or so. So some time passes and it stops mysteriously eating up free space, and I hover around 3 gigs or so for a month or two.

Recently though, it's started to do it again. I had 2.8 gigs free, and then strangely, I checked yesterday and I somehow had only 1.5 gigs available. Now, this is odd because I never save anything to this drive and I don't install programs to it either. Again, I tried to I've tried the obvious solutions, like using CCleaner and other tools to delete all of my temp files, manually deleting system restore points, and uninstalling any programs on the drive I don't really need. Unfortunately, this only manages to free up a small amount, and I'm back to square one. It keeps shrinking even after I free up space, and I feel like I'm losing the high ground here. Is there anything that could be causing this, like a virus or malware of some sort? I wouldn't think so, because I've run a few anti-virus scanners to try to find one, but so far, nothing's been found. So really anything you guys can suggest would be extremely helpful. Thanks.
(And if you need my specs, I'd be glad to post them)

Thanks for the help guys. Unfortunately, it only freed up .3 gigs, but that's better than nothing. I'll have to look around for any files that I can delete to free up so more space. And if there's anything else that could be causing this kind of thing, feel free to let me know what it is, because the Shadow Copy didn't really free up as much as I expected it to.

It the space isn't used by the recycle bin or restore points, you could check the root folder of the C: drive to see how much space your page and hibernate files are taking. You have to set the options on Windows Explorer to show hidden files in order to see these, though.

You could also try WinDirStat. It's a very nice little tool that will visually point you at the folders and files that are consuming the most space on your disk.

I had a trojan once that would do that, occupy free space more and more on your drive.

Did you manage to identify it and/or remove it? Because I'd love to rule that out as a possibility.

Can't remember the name. I was able to remove it without having to reinstall everything.

I've used that program before, it is absolutely great.

Windows updates will also use up disk space. Delete the uninstall folders if your sure you won't need to remove the update.

Where do those folders end up in 7?
