Prevent Internet Explorer from automatically opening PDF documents
The installer for Adobe Reader and Acrobat configures Internet Explorer to automatically open PDF files without any user interaction. This behavior can be reverted to the safer option of prompting the user by importing the following as a .REG file:
Windows Registry Editor Version 5.00
Do not open untrusted PDF files
Do not open unfamiliar or unexpected PDF attachments. Users can convert PDF documents to text by using the Adobe Online Conversion Tools site. See the Online Conversion Tools FAQ for information about this service. This workaround will not mitigate all attack vectors.
