A particularly nasty Flash vulnerability that was discovered when a hacking firm got hacked itself, is already being exploited on the Internet. All users should make sure they are running the latest version of Flash by going here: https://get.adobe.com/flashplayer/  Just be sure to UNCHECK the junkware addon like McAfee Scanner, etc. If you use Google Chrome, click the three bar menu button and select 'About Google Chrome' It will check for updates and prompt you to 'Relaunch' once it's done updating (Google Chrome has Flash built in)
