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.
