The free version regularly scans your device for remote connection tools such as TeamViewer which are commonly used by scammers to get on your computer and steal your personal information. It also blocks all of these websites. This version is why I’m posting because I want people to be protected from scams that my own family have been victims of.
The premium version is only 2 dollars a month and has other features such as blocking thousands of scam websites and notifying select family members if your loved on tries to install one of these connection tools.
If you have elderly or vulnerable family members, consider installing the free version! It’s so quick and could protect everything they have someday.

Pihole runs on a 10-15 dollar computer (raspberry pi) and blocks anything you want, and is free as in freedom software. It is also zero cost.
