Here's the thing. I downloaded a file from a freeware site that had a good rating from WOT. I scanned it using the right click menu. It was clean. I began to install it. Mbam advised it contained a trojan which it quarantined. It's good that I was protected on install, but I'd rather a scan warn me before I install a program. Since Mbam is capable of identifying this trojan, both in the protection module and in a full scan, I believe it should do so in a right click scan too and if not that it should be clear to users that this scan is not as thorough.
How would I know there was a problem with the file if scanning it alone doesn't report it? Is the only reliable way to find out if there is a problem is to always do a full scan, even if you are interested in only one file? Seems counterproductive.
