The 10.0 generation version of Flash and the 9.x versions of Adobe Acrobat Reader are subject to a critical vulnerability exploit that is, as of now, unpatched. In plain English: there is a problem with the above programs versions that makes it possible for a hacker to successfully attack your machine and take control of it.

Flash versions 10.0.45.2 and earlier are affected. Follow this link to find out what version of Adobe Flash Player you have installed in your computer:

While the official patch is released to handle the vulnerability, you can disable flash content display in Acrobat Reader by deleting or renaming the following file:

C:\Program Files\Adobe\Reader 9.0\Reader\authplay.dll.

After that’s done, opening an acrobat document with Flash multimedia content will cause an application crash, but there will be no exploit available for hackers to exploit. If you need assistance with this, I can help you.
