Ok thanks

It seems that it was 78 viruses eating the space,i got rid of them all with malware bytes but they have appeared as obsolete software extentions in Ccleaner's registry cleaner,how can i make them go away?

Thanks for the link!

It was actually a couple of trojans that came with some software eating my space,i deleted them with spybot and uninstalled the software but now i ran registry cleaner and it found ''Unused file extention .c HKCU/Software/Microsoft/Windows/CurrentVersion/Explorer/FileExts.c'',should i fix this or will it bring the virus back?,thanks.

Ah,Thank you.

When i try delete this file http://i58.tinypic.com/rihyee.png it said it is being used in SYSTEM,should i still delete it or is it risky?

Ah,Yes that was it,I just checked and windows made some restore points and i deleted some and got my disk space back,thanks!

Ok,it seems that i got all my space back but its starting to go down again,i'll delete the file,thanks.

No,i'm not running WFS every day and operation system is Windows 7 Ultimate.

I last used Ccleaner's overwrite function in January and I did not reboot and when I tried deleting the file yesterday it wouldn't let me,i have used ccleaner's overwrite function before and it let me delete it or it deleted itself.

Hi,I ran Ccleaner's 'Free Space Wipe' option and after it finished wiping i found a large file called '78f30f3d33620e6672' in 'Local Disk (C:)' and my Hard Disk space is going down by 1 GB a day,Are these Ccleaner's 'Dummy Files' and Can this be fixed? thanks.
