Malwarebytes + Avira

I already have Avast 5 Free and CCleaner.
So,should I install both Malwarebytes and Avira ?

If you want to continue with avast go with it!
I prefer Avira over avast!
If you want to install Avira, Uninstall Avast completely first, restart & then install Avira.

Then at last install Malwarebytes!

It's good to go with one or the other when dealing with AVs. Avira and Avast could fight with each other.

Malwarebytes is simply a scanner, and can be used in conjunction with whichever AV you choose.

Ok,single AV(Avast or Avire) and Malwarebytes.
Do I required third party firewall like comodo except windows default firewall ?
