To speed up your scans, clean out the temporary files..!

close all open programs, do not use the computer during the scan and then make sure you only do a Quick Scan. MBAM is designed to remove malware as effectively with a Quick Scan as it will with a Full Scan which takes much longer to complete. Both do full heuristics, memory, load points and multiple other malware checks. The Quick Scan looks at the most prevalent places for active malware so scanning every single file on the drive isn't always necessary. The Full Scan only has the ability to catch more traces in rare circumstances.
