I was just wondering if these products will conflict

??? I love Comodo’s firewall I currently use malwarebytes Avast antivirus Comodo firewall and threat fire i have been using this combination for a couple days and my computer seems to run really slow and the internet is slow to do these products conflict or do they run fine together

Welcome to the forum. Are you running Malwarebytes in real time? If you are that may be part of the problem. Also, you really don’t need Threatfire with CIS. I’m assuming you have the Comodo AV disabled. You would be fine with Avast & Comodo with Malwarebytes as an on demand scanner in my opinion.

threat fire
I would strongly recommend reading this (below) if you plan on still using threatfire http://www.wilderssecurity.com/showthread.php?t=279612
