The following review written by one of the Software Informer contributors applies to version 1.9
PrivaZer is intended to preserve your privacy by erasing traces of your activity and cleaning unused disk space. It can also erase the history of USB usage, including entries about disconnected devices.
Fortunately, it also lets you selectively eliminate those cookies compromising your privacy.
Its wizard-like interface will probably pose no difficulty. Thus, if you follow the suggested steps, you can easily decide what type of scan to run. As mounted devices are readily accessible with no further action from the user, you can simply pick the desired hard disk, external storage device, USB pendrives, media players, smart phones and network locations and start a scan. After the scan is finished, several viewers will allow you to access data regarding disk usage, contents of system log files, jumplists and thumb cache. Unfortunately, some of the cleaning operations do not allow erasing just specific items.
In general, PrivaZer is said to be effective against well-known recovery software. This is the result of applying smart overwriting techniques. In addition, it can effectively eliminate old elements from the file allocation table. One of its main advantages is that it can perform its activity very fast and its speed increases after various usages.
