Disable Acrobat JavaScript on your Adobe PDF Reader

one comment

If you are using Adobe PDF Reader, there is one thing you must absolutely do if you care about security.


This is very important. Even though Adobe always patches security vulnerabilities in their product, sometimes the exploit comes first and your computer could be infected by some nasty virus targeting the exploit.

The JavaScript feature is rarely used anyway. You better disable it now:

  1. Open Adobe Reader
  2. On the menu bar, go to EditPreferences
  3. Go to the JavaScript tab
  4. Untick the “Enable Acrobat JavaScript” option
  5. Click OK.

Alternatively, you can use other software to read PDF files, e.g. Foxit Reader.
