Do you know for sure that MBAM is set to scan and see if that folder exists? :-) I run CCcleaner, found some missing dlls and deleted them from registry, some temporary files, etc. nothing serious (except it deleted my history from Windows Defender and it now shows me that i haven't scaned in 24 days - since i installed it on my computer). MBAM doesn't show any threat... The thing is that even when I saw MBAM scanned c:\Program Files\Antivir64 it didn't show any threat. I hope MBAM was only looking for that folder and it is not really there...
