MalwareBytes won’t find any cookies because it isn’t looking for them.

Cookies really aren’t a big deal, just deny 3rd party cookies and the so called tracking cookies aren’t getting a look in and SuperAntiSpyware (SAS) is unlikely to find much in the way of cookies. I always disabled SAS from even looking for cookies, I eventually removed SAS Pro as cookies were the only thing that it was finding. Having stopped SAS from even looking for cookies, it seemed a little pointless having it installed.
