I've never been keen on the new version of MBAM because it takes a lot longer to run the basic scan than 1.75 did, but it's at least something.
Can you give me a link for 1.75 and does it still get Definition updates ?
I also have SAS installed and Norton Power Eraser, but you have to click the Advanced button to run the non-Rootkit NPE scan as that can be too aggressive and take out legit programs.
