Improve your security and privacy by blocking ads, tracking and malware domains.
What is this for?
This POSIX-compliant shell script, designed for Unix-like systems, gets a list of domains that serve ads, tracking scripts and malware from multiple sources and creates a hosts file (alternative formats are also supported) that prevents your system from connecting to them.
Is it safe to use?
Absolutely, this script selects only the domain names for each source, so if a domain name is redirected to a rogue server your system will not be affected. In the worst scenario you can lose access to a legitimate domain name due a false positive, but you can reverse it by adding that domain to the whitelist.
Nightly builds
I provide nightly builds of the hosts file and other formats, including installers for Windows (batch file) and Android (flashable zip).
Installation
Manual
curl -o /tmp/hblock 'https://raw.githubusercontent.com/hectorm/hblock/v2.1.7/hblock' \

&& sudo mv /tmp/hblock /usr/local/bin/hblock \
&& sudo chown root:root /usr/local/bin/hblock \
