My recommendation to everyone is: Uninstall Adobe Flash. If you still need it, set it up in Chrome Browser, but set only to load with permission, ie: you have to right-click and activate it on every web site.

Adobe’s Flash plug-in has a big target painted on it. A recent leak shows there’s another Flash Player 0-day that allows attackers to compromise your computer, and that it’s been for sale for the last four years.
