Hi,
I read through some of the help threads and I experienced the same thing as others where the virus was deleting mbam.exe. I renamed/copied it over to the affected machine and the program ran fine. It found over 200 objects infected, so I removed them and rebooted. Then ran the scan a few more times and each time more items would show up. I installed Hijackthis and here is the log file after many scans and cleans from Mbam:
