Before doing anything else please read this McAfee article: Required Reading - Home User Assistance, Malware Troubleshooting
If you can isolate the malware that isn't being detected you can try submitting it to McAfee Laboratories.
McAfee are also developing a new anti-malware tool to help the fight against malware called 'GetSusp'. It can be downloaded from their private group: GETSUSP
Membership is required. You can also discuss it in that group and provide feedback.
If that doesn't help then I can suggest other external tools.
There is no such virus as "Bankerfox.a". If you have seen a message informing you that your PC has been infected by this "virus" then what you have been infected by is a fake anti-virus program which is trying to scare you into paying to have this "problem" removed.
Please see this document for more information.
As for the rest of your post, perhaps I missed something. What was the question?
