Malwarebytes is the one I like best, sounds like you have it covered.

Slushpool was my favourite.  Never had any problems with them.  I liked their user interface.
I do miss the mining days.  Made it all more real, and was fun.  Hope you're able to block this hacker.

Might want to check this Forum section and repost the problem.  Might get help from people that have been-there-done-that.
