AdGuard is an fully featured internet filter that removes ads, ad-trackers and blocks websites with viruses. It’s my recommended ad blocker because it operates as a standalone application, and incorporates a filtering mechanism that is quite fine tuned.
Thus, AdGuard is similar to the free Pi-Hole server, but it is easier to install, and it doesn’t require a separate machine for self-hosting. AdGuard is also more useful than a than modifying a host file. Unlike a host file, it can block www.newspaper.com/trackers.js without also blocking newspaper.com. Moreover, some programs will bypass a host files altogether.
AdGuard also includes a browser extension that let you easily filter web page elements and add blocking exceptions.
AdGuard is made by AdGuard Software Limited — a company founded in 2009 and headquartered in Cyprus.
