The infections on your computer were Trojans, an anti-virus program isn't equipped to look for and remove Trojans. It works on protection against viruses.
Keep the MBA-M program and scan with it at least weekly, be sure to update before each scan. For weekly scanning just use the Quick Scan, if it finds and removes something then use the Full Scan to be sure everything is gone.
You should set a new and now clean restore point by right clicking My Computer. Choose Properties. When System Properties opens click the System Restore Tab. Put a check mark into Turn Off System Restore. You probably will get an alert or warning that it is turning off, click ok or yes, whatever the correct answer is there. Then System Restore will turn off. Wait a moment and do the reverse, go in and take OUT that check mark and System Restore will turn back on.
If you feel everything is solved you can mark this thread Solved.
