I have not seen anything like this on windows 7. But, I know in terminal services, if part of the profile is missing, the whole profile fails to load with a message that it is loading a temporary profile. It sounds like that might be the case here, where either the malware or the fix malwarebytes performed corrupted your profile..
My best suggestion would be to create a new admin profile, use that profile to get as many of your personal files as possible out of your corrupted profile, then delete the profile completely. I do this manually, but the windows 7 account tools might be the best suggestion, and then try manually if that does not work. But, remember the most important first step is to back up the information first.
