Take back control
of your computer.
koalo Guard is a privacy toolkit for Windows that shows you what your programs are really doing, blocks content you do not want, and destroys files for good.
Requires Windows 10 or 11, 64-bit
Watchdog
See exactly which programs are using your microphone, your camera and your location, right now. It also lists everything that is running, everything that is talking to the internet, and everything that starts up on its own when you turn your computer on.
If something is listening or watching when it has no reason to, you will see it here.
DNS Blocker
Blocks ads, trackers, known malicious websites, gambling, adult content and social media across your whole computer at once, not just in one browser. It works by filtering the address lookups your computer makes before it connects to a website, so every program is covered, including ones without any settings of their own.
You choose which categories to block, and you can turn any of them back on whenever you like.
Warning: The malware blocker is not an anti-virus and should not be treated as such, this is just an extra layer of protection.
Shredder
When you delete a file normally, Windows only forgets where it was. The contents stay on the disk and can be brought back with free recovery tools.
Shredder writes over the file first, so there is nothing left to recover. Use it for documents, photos, or anything you need gone for good.
Installing it
The installer is not code signed, which means it has not been registered with a paid certificate. The first time you run it, Windows will show a blue screen that says "Windows protected your PC". Click More info, then Run anyway, and it will install normally.
This is the usual experience for software from independent developers. Those certificates cost money every year, and koalo Guard is free.
Administrator rights and your data
When koalo Guard starts, Windows asks whether you want to allow it to make changes to your device. It needs this because the DNS Blocker changes your network settings, and Windows does not let ordinary programs do that.
If you say no, the app still opens and Watchdog and Shredder work as normal. Only the blocker stays switched off.
Everything the app shows you stays on your computer. There is no account, and nothing is sent anywhere.
Free. No account needed.
