Running Bitdefender with Malwarebytes

[whose1]

New here.......saw something about, "what to run with Malwarebytes?"    I have been running bitdefender for months and I am giving up.   There support told me my "other" security programs were interfering and I should remove.  I did and got a malware hit which bitdefendeer missed.  I reinstalled Malwarebytes and it found and removed "it" immediately.  Now looking for something else.  Ran Avast pay and free for years and I think I will  try that.  Also, bitdefender wanted me to disarm a hole  bunch of stuff and then rearm and use one at a time.  I have a life.  That is not going to happen.  They wanted to find out who or what was the "culprit".   I asked for my money back.  We will see.
