No Profiles in System Preferences

I'm trying to delete the weknow.ac malware from my mac, and one of the recommended steps is to open System Preferences, click on Profiles, etc.

The (first) problem I'm having is that there's no Profiles icon. To fix THAT problem, another thread here said to "click the Finder icon in the Dock, choose Go>Go To Finder, Type ~/Library/Caches"...

I'm in Finder, but I don't see any option to "choose Go," etc.

Can someone point me in the right direction? TIA.
