Per Mr. Krebs Security there is a new Java update.  If you see the notification down below near the time, please update your system.  This protects you from drive by downloads meaning if you browse even a legitimate website such as staradvertiser.com, Yahoo! News etc. you can still be hit if their site is compromised with hacked ads or some other exploit.

As always if you are having problems installing it, we’re available for help remotely or in shop.
