Improve your security and privacy by blocking ads, tracking and malware domains.

These are the exact words from the developer, Héctor Molinero Fernández, on his github site:

This tool will basically change your hosts file in /etc so that 100.000+ domains will be blocked.

We have build a package so the application can be easily installed and updated!

All you need to do is install the application and run it once. A timer and a service will make sure that you will get the latest blocked domains at a certain interval.


A backup will never hurt anyone.
