We recommend the following actions be taken:

Apply appropriate patch provided by Microsoft to vulnerable systems immediately after appropriate testing.
Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
Remind users not to open email attachments from unknown users or suspicious emails from trusted sources.
