<<...cleared of malware for the most part, but...>>
Statements like that...always intrigue me
Malware is a disruptive, annoying fact of life. A system is either clean...or it is infected.
<<I know that it was the trojan that did that, though why did it happen after the MBAM scan? I don't get it..>>
Mistakenly...many users think that there is some application that can be used to eliminate all forms of malware. Many seem to think of Malwarebytes in the same manner that you seem to...as something capable of detecting/eliminating/neutralizing all forms of malware.
It just ain't so.
Protection from malware starts with installation of critical updates...is aided by installation/updating/usage of a reliable AV program...and is aided by the usage of any number of programs which address malware but which are not AV programs.
Malwarebytes is one of the latter type of programs...it doesn't detect all forms of malware, nothing does. It's merely an additional step which users can take to protect their systems. And...it's not necessarily the only step that should be taken, even in conjunction with a reliable AV program.
In fact...if you visit the Malwarebytes forums or our own forums which address known infected systems...you will see that a variety of other tools
are used in order to attempt to correct systems which are infected.

Dealing with malware...is just not as simple as many users seem to think it is or should be
<<...that's when her .exe file association was no longer associated correctly. I know that the fix for that is really quick. Does anyone know what key that is that has to be added into the registry?>>
Disregarding the malware issues...there are several scripts which address file association and other fixes. You might take a look at http://www.dougknox.com/xp/file_assoc.htm
