I've been told that a site I visited recently is a Cookie Logger, does Malwarebytes block cookie loggers? And what do cookies store about you(does it have access to your webcam, know your location etc..) Cheers.

When I start a scan in Malwarebytes, the current item keeps displaying adware and PUPs Malwarebytes keep telling me that there is no threats and my Mac is clean, is this normal?
