PrivaZer is an interesting free tool that adds to our maintenance utility kit , indispensable for any user who wants to keep their disk drives clean and thus optimize the overall performance of the system.
The innovative thing about this program is that it is focused on maintaining your privacy, since it eliminates all traces and activity of the use of the PC, hence its name. Deleting history, application use, registry, downloads, among others, while freeing up hard disk space and making your computer faster.
As you can see in the screenshots, PrivaZer is available in Spanish, as well as other languages. Its interface design is simple, intuitive, and clearly labeled for each item you select. Both basic and advanced users will be able to take full advantage of each of its features.
The analysis it offers automatically detects the system unit, but if what you need is to clean your USB devices, it has support for USB memories (USB Key), external drives, players, SD memories and others that can be seen in the following screenshot.

Regarding the background analysis, it is responsible for eliminating Internet activities, use of programs, useless files, USB history, obsolete files and other cleaning settings to select.

PrivaZer is 3.57 MB in size. When you run it, you can choose between installing it or creating a portable version, which I find interesting. It is, of course, compatible with Windows 7/Vista/XP.
