As promised by Adobe, Acrobat 7.0.9 has been released to address a cross site scripting vulnerability. If you are running version 7.0.8 and prior, you should seriously consider to upgrade. Although there are reports that certain combinations of browsers and Acrobat versions are not vulnerable, upgrading might be the easiest path to ensure vulnerability is gone.

This link will get you to download the latest copy of Acrobat version 8, it is not vulnerable to the XSS vulnerability. If you must stay at version 7, there is a link on the same page to download other versions.
