In line with the Adobe Support Lifecycle Policy, Adobe’s Acrobat 9.x and Reader 9.x suite of products reached their end-of-life (EOL) today, June 26, 2013. This means that Adobe will no longer provide security or other updates to this product suite.
Over the years, we’ve made several security enhancements in the successors of Reader 9, Reader X and Reader XI, including the Protected Mode (aka “sandboxing”) and Protected View. There has never been a better time to upgrade to Reader XI. Please upgrade, ensure automatic updates are turned on, and stay secure!
