só posso dizer que é excelente

Absolutely invaluable extension. I use Malwarebytes Pro on my desktop and this extension on all my browsers. It does flag some places that are ad based, and it's easy to back out of those, or if you know the site is safe, proceed. Just a great tool.

It's an essential extension for me. I would not surf the Internet without it anymore. It keeps me safe from all kinds of threats on the Net and even gets rid of most of the annoying ads you come across. Highly recommended!

Excellent add-on for safer browsing, without all the annoying bloat that other AV-providers implement in similar products.
