So many traces ! That's not surprising.


When you use your PC (at home or working at your office), go on Internet, watch a video, download, copy/remove files on your PC, install/uninstall or use software, etc
you always leave sensitive traces which :


- makes your PC slower and cluttered
- reduces free space available and
- puts you at risk for a bad consequence :
  what you have done could be easily recovered
  by analyzing your PC
  with an expert recovery software
  or with more advanced techniques.

Then, we decided to develop a new type of cleaning tool
to give you the peace of mind that once your data is gone,
it is gone for good.
See innovations included in PrivaZer below.


We believe that PrivaZer should be accessible to all
to preserve freedom and security.
That's the reason why PrivaZer is a free PC cleaner.




 

How to test PrivaZer ?

See performance tests
 

TEST NO. 1
Smart cleanup of free space

. Scan and clean traces in free space with PrivaZer
. Note elapsed time in the cleanup window
. Do step 1 again and compare elapsed times

You should notice that 2nd cleanup is much faster than 1st one.

Comment : smart cleanup of free space is available for all FAT and NTFS formatted drives
and for C:\ drives if formatted as NTFS (which is generally the case)

TEST NO. 2

Detection of residual traces in free space

. Download free version of sdelete from Microsoft website : here
. Reset to zero free space with sdelete (use option -z to zero current drive free space)
. Scan traces in free space with PrivaZer

PrivaZer should detect no trace in the free space.

Comment : a minimum level of traces will always be detected on your C:\ drive.
Your system is running so that it continuously creates, moves, deletes temporary files.

So you'd better perform the test on a second internal or external drive.

. Reset to zero free space with sdelete (use option -z to zero current drive free space)
. Copy a file of about 100 MB or more in size
. Delete the file
. Empty recycle bin (to be sure the file is really deleted)

. Scan traces in free space with PrivaZer

PrivaZer should detect residual traces left by the file
- in the free space (red color) and
- in the file table (FAT or MFT)

TEST NO. 4
File recovery prevention

. Download free version of recovery software like GetDataback : here or Recuva : here
. If you intend to use GetDataback, be sure to have checked "Recover deleted files" in "Options"
. Scan recoverable files with it
. Clean with PrivaZer traces in free space + traces in MFT or FAT
. Scan again recoverable files with the recovery software

The recovery software should no longer detect recoverable files.
