Mac Users need to be aware of Fake Adobe Flash Updates (as do PC Users). As I always tell people – go to the source for your updates
Adobe products – go to www.adobe.com to get your updates (you may also receive an Adobe Reader icon in the system tray to update Reader, those are OK, they appear about once a month)
Java – go to www.java.com to get your Java updates (you will get an orange Java icon in the system tray (next to the system time/date)). Those are also OK and appear about once a month or as needed.
