Protect Your Computer from Flash Exploits
The best way to protect your computer from Flash is not to install it to begin with or to uninstall it. However, that isn’t a realistic option for millions of users. If uninstalling isn’t an option, we recommend you enable the Click-to-Play option in your browser(s). That will stop Flash ads from automatically rendering and help avoid an attack. Then, if you need to use Flash on a site, you can enable it yourself manually.

Also, always make sure your antivirus software is up-to-date. Whether you’re running Windows, Mac, Linux, or Chrome OS, always make sure your system’s operating system has the latest security updates as well.
These critical and emergency patches for security holes in Flash are becoming a monthly, sometimes weekly, event. This latest update comes after last month’s emergency patch against a Ransomware attack.
