KEUbvKya process run in my macbook and using 99% cpu and 4gb memory .I Cannot End prccess Plz see the picture
Open the Terminal app in the Utility folder.
kill -9 2746
that is sending the kill command (9) to the Process ID 2746 which is your (KEUbvKya process).
If it reincarnates (comes back to life) then we need more info to find out who is behind it. Please report on it.
