After reviewing some other posts I ran across a fix for this problem.
Malwarebytes was not being updated because the trojans on the computer were blocking the update process.
Following the process about installing MBAM on an un-infected computer, updating it and transfering "rules.ref" as outlined in the post at [malwarebytes.org/forums/index.php?showtopic=6844] allowed me to update Malwarebytes, run its scan and fix the problem!
All the issues I noted appear to be corrected.
I can now run regedit, searches work correctly and sites are no longer blocked.
I would highly recommend anyone having similar problems try this tool.
It is excellent.
