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: https://github.com/hectorm/hblock

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.

RUN ONCE AND FORGET ABOUT IT.

A backup will never hurt anyone.

You can read more about what it is for, is it safe to use, sources, … on his github.

Best ALTERNATIVE
Use the command
hblock -b
to make a backup of your /etc/hosts file

This was the original content of my /etc/hosts file.

Just for reference and backup.

whitelist & blacklist

Update your system to be sure you have hblock-git 2.0.

Or install it now

Then type this command in your terminal to start it all

Add the whitelist domain names in 

/etc/hblock.d/whitelist

and the blacklist domain names in 

/etc/hblock.d/blacklist

In the video you see me whitelist analytics.google.com with success.
