hBlock - Block All Domains That Serve Ads, Tracking Scripts and Malware

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 reputable sources and creates a hosts file 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 installers for Windows (batch file installer) and Android (flashable zip).

Installation

curl -o /tmp/hblock 'https://raw.githubusercontent.com/zant95/hblock/v1.3.3/hblock' \
  && echo '148806074480956fa4f559a38f057cd0904adff19dc7d83bb33e0c25e9c99a34  /tmp/hblock' | shasum -c \
  && sudo mv /tmp/hblock /usr/local/bin/hblock \
  && sudo chown root:root /usr/local/bin/hblock \
  && sudo chmod 755 /usr/local/bin/hblock

Note: you can use this Systemd timer to regularly update the hosts file for new additions.

Optionally, it is possible to use NPX to run hBlock without installation

npx hblock
