My son was also infected with this rogue/fakerean but did not get the Alurean rootkit. After getting security center back up and running on both PCs, we both had the same issue: Security Center reported that Windows Firewall was not turned on. Clicking the button to turn on the firewall would result in an error 0x8007042. It appears that this monster had also deleted the following keys:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\MpsSvc] (windows 7 firewall)
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\bfe] (Base Filtering Engine)
In Services.msc both the Base Filtering Engine and the Windows Firewall services will not be there, so you can't turn them on.
I have a rather involved solution that includes importing these keys from a good PC. I'm not in front of the Windows 7 box right now but I can post some detailed instructions plus good keys for both 32 bit and 64 bit, if anyone is interested.
