Malwarebytes has had a few (seemingly) false positives lately. Anecdotally, I was just hit by it falsely flagging BeyondCompare and my password manager.
I assume they have just upped the ante of their heuristics, but am still concerned about the fallout, since I am starting to ignore them.
Not related, but considering that it does not scan except on demand, why is it ALWAYS running? Who vouches for Mr. Malwarebytes?
