Hi all. I am a newbie so be gentle with me please! You probably all know the answer to this, so hope someone can advise. I have windows 7 with Avast free antivirus installed. I think it is fantastic and probably the best antivirus I have had to date

. And that includes paying for many of them.
I have recently had messages coming up saying windows defender needs to do a scan. So I did. Now it keeps asking me to scan. I don't even want it as understand it isn't very reliable

. I would like to disable defender and rely on my Avast firewall as my computer is running really slow and I believe it could be that the 2 antivirus are at odds with each other. I am assuming it was activated with a windows update maybe? But first I need to know the following.
1. Does the firewall come with the free Avast? (my computer advises firewall on but don't know if it is defender or Avast).
2. If so, how do I turn defender off?
3. How do I ensure Avast firewall is on?
I hope someone can help me with this,
Thanks, Chrisw
