At present I am running ZA Free and I have been very happy with it, so much so, that I would like to upgrade to ZA Pro.

I have been searching the forum for information, maybe I've missed something but I cannot find a thread relating to this subject, and my question
is "After having bought ZA Pro, is it downloaded over the top of ZA Free, or does Free have to be uninstalled first"?

ZA is running on Vista Home Premium SP2, with Avast4.8 Pro, Malwarebytes and Superantispyware.

I look forward to any help you can provide me.

Best wishes,
