false positives

Lately, Norton's has gotten overly aggressive with legitimate programs:

1)malwarebytes

2)Megascenery set up files 

3)Paperport

 

Norton blocked files for the above that came directly from the companies. I even contacted them and a couple of them already knew about the problem. Of course, we all want vigorous defenses, but increasingly it seems to be blocking legitimate programs causing them to fail.
