I had the same problem, used one click root program to root my vibrant again. Then I downloaded "super manager" from the market. opened super manager went to apk, scrolled to the bottom found mcr scripts destonation ( system/app/ase_mcr_r25.apk) then I downloaded "terminal emulator" from the market. Open terminal emulator and type; (note you need to have superuser (su) permissions to do this)
$su
# rm -r /system/app/ase_mcr_r25.apk
This removed it for me, make sure you verify the location on your phone. I'm not sure if it would be the same for you.
hope this helps
