Very few websites require the use of Adobe Flash Player now, so you’re better off uninstalling it altogether. However, if you need to keep it enabled, please take steps to prevent it from automatically running without your permission.
Secure or Turn Off Adobe Flash Player
If you’re on Windows 8.1 or 10, make sure you have all your Windows Updates. That’s how Flash Player gets updated on those systems. Edge usually asks for permission to run Flash Player the first time you visit a site, then remembers your preference after that.
- You can turn off Adobe Flash in Edge by selecting the three dots (…) in the upper-right corner right below the Close (X) button
- For Internet Explorer, click the “gear” icon near the Close (X) button in the upper-right corner.
- Select Manage add-ons
- Leaving Toolbars and Extensions highlighted, under the Show: dropdown, select All add-ons
- In the list, double-click Shockwave Flash Object
- If there is an asterisk (*) in the box You have approved this add-on to run on the following websites:, click the button Remove all sites
- Click Close, Close
- For Google Chrome, paste chrome://settings/content into a Chrome browser bar and then select Flash from the list of items. By default, it should be set to “Ask first” before running Flash, although you also can disable Flash entirely here by moving the slider to the left, or you can whitelist and blacklist specific sites.
- Firefox is already asking users whether to run Flash Player on a per site basis. We don’t use Firefox here that much, but it seems you might be able to turn it off by selecting the Shockwave Flash plugin and choosing Never Activate.
Patch Tuesday for February 2018
February saw over 55 security holes patched in Windows, Internet Explorer, Edge, Microsoft Office and Adobe Flash Player. (Remember that Flash Player is included with Edge.) Many of the fixes carried the “critical” designation. All supported versions of Window Server (2008-2016) as well as Office products (2007-2016) are affected by at least some of these vulnerabilities.
One particularly worrying exploit is in Microsoft Office. If the user is convinced (usually through phishing) to click a malicious link, open a boobytrapped document, or visit a compromised webpage, your PC could be compromised. The Adobe Flash Player vulnerability is also being exploited now.
Adobe Acrobat and Reader also saw updates during the month of February as well as Firefox and Thunderbird, and iTunes and iCloud.
