I run MVT quite often -- it does not find any problems. Later I find that there are problems with script in McAfee product. MVT should find them, not just say everything is fine when it is not.
Often it needs to catch up with the product. Yes I know, it should be the other way around as it's supposed to fix the software. Well it isn't a perfect world is all I can say.
Off to friends for the rest of the day soon so wont be here to answer anyone for a while.
