I'm not sure if this problem comes under Spybot but something strange is happening to my Hard Disk. My computer was running slower than expected and I realised the hard disk only had 25 Gig (Out of 225 Gig). I've tried to find out where all this space is being used but nowhere can I locate any files that could be filling up this space.

I've tried deleting all the large files, like movie files etc not system files, but then without downloading anything or installing anything the space appears to be still vanishing and the amount of space freed up does not match with the space deleted.

I was hoping that somebody might be able to help with this. I've attached the HJT log, I think I've done it correctly but if I haven't then please let me know.

Thank you in advance.
