Install the updates provided by Adobe immediately after appropriate testing.
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
Remind users not to visit websites or follow links provided by unknown or untrusted sources.
Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from un-trusted sources.
Apply the Principle of Least Privilege to all systems and services.
