Other than PDF this service also allows you to send images and other office documents. Reader X is also tightly integrated with Adobe SendNow, an online file sharing service. Using this service you will be able to send the PDF document you are reading to anyone without having to launch an email client. So, if you open a PDF document which has scripts include that may try to change your computer’s file system or registry settings the “Protected Mode” will protect you against it. With Protected Mode enabled, all PDF file operations will run in a restricted manner inside a confined environment, the “sandbox”. It is similar to the Google Chrome sandbox and Microsoft Office 2010 Protected Viewing Mode. Protected Mode is a sandboxing technology based on Microsoft’s Practical Windows Sandboxing technique.
Adobe had announced the upcoming version of their Acrobat Family of Products last month with a new feature that provides better security via “Protected mode.” This feature is enabled by default in Adobe Reader X.
