Earlier this week Microsoft released their monthly package of updates to the general community.  Most notable of these was MS12-037, which affects all recent versions of Internet Explorer (6, 7, 8, 9).  This update has been rated as critical and it has been recommended that everyone apply this as soon as possible.  Windows users can always visit the Microsoft Updates page to have their system checked for any available updates.  Mac users should run Software Update, found in the Applications folder, on a regular basis to ensure optimal system performance.
