There have been a few vulnerabilities lately with Adobe Acrobat Reader handing malicious javascript badly and this post is to show how to disable javascript in Acrobat Reader.  While disabling an entire piece of functionality seems a bit like over kill, there are a couple of reasons that you may want to do this.
