Windows 8 Defender AND Comodo Firewall?


When I tried to scan today with Windows Defender on my recently upgraded Windows 8 computer it told me it was disabled because other spyware software was active and it brought up the spyware action centre showing an entry for Windows Defender and Comodo Antivirus.

I was only able to access Windows Defender by disabling Comodo Antivirus from this action centre.

Is there anyway I can have both pieces of software working at the same time alongside each other at the same time?
