MS anti spyware was picking LW as a spyware before....
Try BS lite with Spybot and Adaware. I do not trust others, because they are not testing enough their tools. I thought MS was ok now, but it doesn't seem so now. Do we need a gazillion anti spyware tools just beause that's a lucrative market? (exploit users as usual...)
I've installed BS lite many times and never got spywares. By your screenshots it seems MS anti spyware just picks anything BS related as spyware, indicating MS antispyware is crap. That's the only logical conclusion I can get from the screenies.
