A scan with Malwarebytes is unlikely to identify your Anti Virus programme as a PUP. However you could be surprised by finding that, perhaps unknown to you, there are a number of Malware items in your computer which can be safely removed after having first been quarantined for a decision from you on the question of their removal.
Everyone should have Anti Virus and Malware programmes; but only one of each so as to avoid conflicts which can be really problematic.
