Your version of Adobe Reader is out-of-date anyway.
The mDNSResponder.exe process belongs to Bonjour which is installed automatically by iTunes.
Note: Don’t remove Bonjour if you use iTunes to share libraries, or any other feature from an application that relies on it
However, reinstalling iTunes should fix any errors.
I suggest you uninstall Adobe Reader, all versions of Java and Bonjour.
Visit Adobe and download the latest version of Acrobat Reader.
Install the latest version of Java:
NOTE – when you install Java, before clicking on Install, be sure to uncheck “Install the Ask Toolbar and make Ask my default search provider”
Note: Even though I just had you get the latest version of Java, there is a vulnerability with regards to Java and web browsers. Therefore, we recommend to disable java in web browsers.

Let me know what happens when you have done this.
