Adobe Reader software is the global standard for electronic document sharing. It is the only PDF file viewer that can open and interact with all PDF documents. Use Adobe Reader to view, search, digitally sign, verify, print, and collaborate on Adobe PDF files.

A 3rd party speedup tool for Adobe Reader is also available. It disables many of the plugins that are not needed. It has an easy to use interface including a couple of speed options as well as restore to default. Download that here.
