My Windows 7 PC became infected with the so-called "Malware Protection designed to protect" trojan while I was at work the other day.
I managed to kill the process so that the malware is no longer running.
The removal instructions specify to delete the following file: c:\documents and settings\all users\application data\defender.exe
However, when I click to c:\documents and settings, it says "Access denied". Prior to this malware infection, I've never had any trouble accessing "Documents and Settings" or "Application Data."
I read that in Windows 7, c:\documents and settings is a psudonym for c:\users, but I still cannot find the file defender.exe.
