Staying secure online is important, as is maintaining your privacy. One way to do this is to manually delete your cookies and cache after every session, but this can prove hit-or-miss, not to mention time-consuming.


For some, a dedicated solution for PC deep cleaning is a better and more convenient option. Here’s how PrivaZer can help with that.

What Is PrivaZer?

Clean the Windows internet cache with PrivaZer

Developed to help keep your Windows PC clean, PrivaZer is an alternative to tools like CCleaner with a much more focused approach to cleaning and protection.

Whereas tools like CCleaner have a bunch of extra tools like a duplicate files finder and a disk space cleaner—which some users might consider bloatware—PrivaZer concentrates only on enhancing your privacy.

Different degrees of cleaning can be done with PrivaZer, but it is especially good at dealing with internet cache files, downloads, and cookies.


How Cookies Betray Your Online Privacy

Essentially text files storing user-specific data, cookies are useful for browsing the web, but they’re not exactly on your side.

The Two Versions of PrivaZer

Install PrivaZer on Windows

Available from, PrivaZer comes in two versions: Free version and Donor’s version (which offers extra functionality, such as automatically cleaning internet activity after each session).

Each of these can be downloaded as a standard installation or as a portable version. Further, the standard version, when run, gives the option to install, or run without installation. And in case you made a mistake, there’s also the option to create a portable version from the installation wizard.

You may have spotted benefits for each option. A portable version of PrivaZer can sit on a USB flash drive, waiting to be run. It requires no installation, and as such can be used on any Windows system at any time. Need to investigate some slow performance?

With each function, the process is largely the same: select the type of clean, choose the data types/location to analyze, then click Scan to commence.

The results are invariably good, and you can even clean traces from your system registry, and USB devices. There’s even the option to run a scheduled cleanup (although this requires the installed version of PrivaZer).
