I have been having the same problem daily for the last weeks. I noticed this both with the 6.4.128 and 6.4.200.1 version.
The only way to stop my MacBook Pro (Retina, 15-inch, Early 2013) from making noise with the cpu fans, is by force-killing the esets_daemon process. But a while later, it starts again, and goes back to 100%. Very annoying!
Top -o cpu gives me:
