Hello,
Can someone please, please, please help me.
I have a Windows 7 Pro machine, with 500GB and recently it has been decreasing in hard drive capacity to the point I had only a few GBs left, so I decided to get rid of some large old files - it turns out - the MORE I DELETE THE LESS SPACE IS ACTUALLY FREED UP!
As illogical as it may seem, I’m not on crack!
Clearly this must be due to some sort of virus since I happened to have carried out a full scan scan my system (just felt like doing it, not suspecting anything - I have a good habit of scanning every couple of months!) yesterday using AVAST (free edition) and nothing turned up. However when I did a preboot scan two or three trojans came up which I deleted - only for this problem to come up today.
What do I do?
I now have 0 bits of free space - none whatsoever on my C drive.
I neither have a backup copy or recover disk created because I was unable to create a HP Elitbook recovery disk due to some technical issues.
Any assistance would be kindly appreciated as I have some very important work to do and can’t afford to waste days on end trying to sort this out - I might just throw it out the window on to my car!
Thank you once again 
Hi VAIO-II,
Very unusual.
Would you please follow the instructions here: http://forum.avast.com/index.php?topic=53253.0
and attach given logs.
Hi !Donovan,
Thanks for your response, I shall do that as I soon as I am able to.
Thanks again for your response.
Hi,
Sorry, did you want logs for malwarebytes antimalware ? I won’t be able to install any programs because I have 0MB of free space of 500GB on my computer (not this one I’m using at the moment).
So I won’t be able to install any programs.
I guess u have no malware but a very small issue…Clear the system restore it occupies alot of space
right click on my computer>>choose properties>>click on system protection>>click configure>>choose delete[The screen may freeze for a minute or so after clicking delete be patient]>>create new restore point again
follow number in screenshots for steps
[1,2,3,4]
then clear temp files see here and follow instructions: http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/
Important Update:
I think I’ve found the culprit: Jetico BCWipe. I’ve never used this program(I bought the laptop from gumtree & have left most of the programs it came with because they seemed useful) but there’s a folder in the C drive which is a hidden and called: ῀BCWipe Del" …I think it has the ‘Del’ part…
So here’s what happened:
- This folder had a file that was 69.4GB…
- Everytime something was being deleted from browser cache, temp folders, Recyle Bin etc it was going to this folder…
- When Recyle bin is emptied it was going to this folder…
- I managed to delete this 69.4GB file BUT…
- All the other mini files ( 20KBs<) & there were thousands upon thousands (>10K+) which were not more than 50MB could also be deleted via simple delete or shift+delete BUT…two things…first these mini files kept on increasing and more were flooding into this folder and I was playing cat and mouse trying to delete them to no avail (& at the same time my C drive is decreasing in available space as these files pile up!).
- I tried to delete BCWipe…it wouldn’t let me…an error
- Used RevoUninstaller to remove this program and that folder “BCWipe…” dissapeared! Horroa!
I looked at my AVAST log and found the following 4 virus/trojans deleted from last scan during bootup (I recall two were trojans at least and were deleted by Avast)L
- Win32-Delf-MBA [Trj]
- Win32LDelf-MBA [Trj]
- PUP Win32-gen [PUP]
- PUPL Win32LPUP-gen[PUP]
So all in all people a happy ending
I now have Malwarebytes installed, scheduled weekly scans, I don’t have this nasty folder filling my C drive up with useless files and I’m happy 
Moral of the story, if you buy a laptop from ebay/gumtree make sure you do a full scan or remove programs you don’t need!
Any thoughts, insights people?
Thank you once again for your assistance, greatly appreciate your time.
Glad to see your problem was fixed! 
I hope it was fixed because I did a full scan with malwarebytes and it found another object :o
Thanks once again
