Malwarebytes is good (update it daily) - it recently saved my machine. You can keep Spybot, but you need to deactivate its immunization feature. As I recall, that is under advanced settings. Personally I have just removed Spybot and rely on Malwarebytes free, AVG free, Zonealarm free firewall, and Windows Defender. I don't even use Adaware any more. IE8 is a key part of the Windows operating system with significance beyond the obvious - so you can't really just abandon it for Firefox - although I am actually at this moment writing this SOH message in Firefox!! :mix-smi:
