Security & Privacy + Software & Apps

Yesterday, in an article about a zero-day Adobe Acrobat and Reader threat, we posted instructions about how to deactivate Javascript in these two applications. There is little need for this to ever be activated anyway, so you might as well turn it off to protect yourself against this current threat, and against future vulnerabilities that may arise with these programs.

Adobe has issued a security bulletin telling users how to deactivate Javascript. So if you missed it, here’s what you need to do. In Adobe Reader or Acrobat, choose Preferences > Javascript, then uncheck Enable Acrobat Javascript. That’s it; uncheck that option, and you’ll be safe. And keep it unchecked unless you know that you absolutely have to use Javascript in one of these applications.
