"Unable to forget Hot Spot" - Can't disconnect from it either I am running stock kitkat (4.4.4). There are some hotspots my phone will connect to whenever I am near. If I try to disconnect from it, I get an error message that says:

Unable to forget Hot Spot (sic).

My only options are to disable WiFi or keep connected.

If I am not near that hotspot, it won't even show up on the list of memorized hotspots.

What is happening here?
These are probably hotspots set up by your carrier, designed to reduce load on their 3G/4G network by offloading some of it to WiFi. You would not be able to prevent using these unless you turn off WiFi (why is that a problem for you?) or root / use a custom firmware.
