Adobe has issued updates to fix critical security problems with both its Flash Player and Shockwave Player. If you have Shockwave installed, please consider removing it now.
For starters, hardly any sites require this plugin to view content. More importantly, Adobe has a history of patching Shockwave’s built-in version of Flash several versions behind the stand-alone Flash plugin version. As a result Shockwave has been a high security risk to have installed for many years now. For more on this trend, see Why You Should Ditch Adobe Shockwave.
Same goes for Adobe Flash Player, which probably most users can get by with these days just enabling it in the rare instance that it’s required. I recommend for users who have an affirmative need for Flash to leave it disabled until that need arises. Otherwise, get rid of it.
Adobe patches dangerous new Flash flaws all the time, and Flash bugs are still the most frequently exploited by exploit kits — malware booby traps that get stitched into the fabric of hacked and malicious Web sites so that visiting browsers running vulnerable versions of Flash get automatically seeded with malware.

If you choose to keep Flash, please update it today to version 18.104.22.168. The most recent versions of Flash should be available from the Flash home page. Windows users who browse the Web with anything other than Internet Explorer may need to apply this patch twice, once with IE and again using the alternative browser (Firefox, Opera, e.g.).
Chrome and IE should auto-install the latest Flash version on browser restart (users may need to manually check for updates in and/or restart the browser to get the latest Flash version). Chrome users may need to restart the browser to install or automatically download the latest version. When in doubt, click the vertical three dot icon to the right of the URL bar, select “Help,” then “About Chrome”: If there is an update available, Chrome should install it then.
