Can You Run Malwarebytes With Another Anti Virus Or Anti Spyware Program Already On Your Computer?

I’m thinking about ditching Windows Defender because I know it sucks, and it came with Norton Internet Security 2008, and I know I have talked bad about Norton, but they have improved greatly from the past, and it doesn’t slow my laptop.
I’ve read and heard so many great reviews about it, so if I have Norton, Super anti spyware, can I run malwarebytes along with them?

What Are Some Good Firewalls And Anti-spyware Software For Vista?

I’m currently running AVG on my Vista Home Edition for my anti-virus, but I would like to find some decent firewalls and anti-spywares that I can use. I was using Windows Firewall, but I heard it wasn’t as good as others. I’m also using Windows Defender, but I also heard it’s good to have another anti-spyware program along with it. Ad-Aware 2007 doesn’t work with Vista yet, so I need something good. Any suggestions would be appreciated.
