I have ran Spybot and BitDefender. I have tried to remove the XX from Spybot - but it returns - even in Windows "Safe" mode. Bit Defender says I also have trojans - but could not remove them. What can I run to get rid of both of these?

From Spybot it reads:
Microsoft.WindowsSecurityCenter.FirewallDisabled: Settings (Registry change, nothing done)
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\windowsfirewall\domainprofile\enablefirewall!=dword:1

Microsoft.WindowsSecurityCenter.FirewallDisabled: Settings (Registry change, nothing done)
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\windowsfirewall\standardprofile\enablefirewall!=dword:1
