Will Malwarebytes conflict with Avast 4.8 (Vista)?

I know having more than one anti-virus program enabled at one time can cause some conflicts but I need a decent anti-spyware program… I’m using Ad-Aware but it sucks, it screws up all the time and half the features are blocked on the free version. I use Avast 4.8 for my anti-virus program which I am happy with and I do not want to remove it so there’s the problem. I know malwarebytes also protects from viruses so I’m wondering if removing ad-aware, keeping avast and then downloading malwarebytes will cause any conflicts on my machine.

As said, they won’t conflict. Another good thing about Malwarebytes Anti-Malware is that it won’t slow your computer down because it only runs when you tell it to, not all the time. I too use Avast and I’m quite happy with it as well.
