Speaking from my experience, it is blocking the installer and the installed program based on the name of the executable. Simply rename the installer and exectuable and it should run fine. You will also have issues getting it to update until you've cleaned it up a bit. I usually just copy and paste the executable within the same folder which results in "Copy of [mbam.exe/mbam-setup.exe]" which then runs fine. It does the same thing to several other software packages, such as Spybot S&D and AVG Antivirus (sometimes; haven't had a problem with Avira though). I have also seen it block Taskmgr and Regedit in a similar fashion, and the same work around bypasses it. Ba'alzemon d#%n typos!
