SSD filling up without reason or obvious cause?

When I made my first built in May I decided to save some money by only getting a small 30GB SSD as boot drive. Like on the laptop I had before, Windows 7 took up roughly 17GB. All 'My blabla' folders were moved to the 1TB HDD and no programs apart from Google Chrome were installed on C:. It was perfect. -until roughly one month ago when I noticed that the initial 10GB+ of free space on the SSD had dropped to 8. Then 5. Then 2.
Cleaning the system brought back about 500MB but that wasn't enough to solve the problem. So I brought a new SSD, 111GB this time, cloned Windows to it...and to my horror just saw that now, 2 weeks later, free space has dropped to 70GB; I did absolutely NOTHING with the SSD during that time. :|

Virtual memory is not on it, the TEMP folders are moved, system restore points are turned off too (I even removed all of Windows optional 'features' for Gods sake) and if I sum up the sizes of all folders on C: (including the hidden ones) that's ~23GB. Aka there are 18GB of data on my system which can't even be located. And it keeps getting more and more.

I'm very much at a loss right now...any ideas what could be causing this? A virus perhaps? :/

download Spacemonger. it will read the drives and tell you exactly what is on it and exactly how much space each piece takes up. this program will allow you to see what is being added to the drive.

the program says it's a trial but i have never had to puchase it even after the trial period ened. very handy when space is being taken up from seemingly no where.
