It works very well. I use it in combination with my Bitdefender Total Security suite, which includes Anti-tracker, & Ghostery. I also use RoboForm to generate & remember very complex unique passwords. I use a Windows 10 computer. I also don't accept 3rd party cookies by default. I clean the cookies regularly. If I want to visit webpages that all these precautions don't work with, I tweak as necessary. Also I don't store anything valuable on my hard drives. I use 4. I have an old HP tower computer with a Intel 3.67 GHz core i7.
