*bump* Can no one help? This happened again today I lost another 2GB instead of gaining it

I just updated to the new version 2 of CCleaner, however I ran into a problem. When I ran it it said it had found around 4800MB to clean, before I commited the clean I checked my drive space, there was 92.5GB left. After commiting the clean and waiting for it to finish (I use the secure 7 pass method so it took a while) I checked my drive space again and there was 91.2GB left. So basically why didnt it give the 4.7GB back and where is the 1GB it seems to have added to the drive? So in total its around 5.7GB lost I have been using CCleaner for years and never came across this happening
