Ah, with a touchscreen, you are basically clicking when you touch.
In Acrobat's preferences, you can disable that: Select the "Full Screen" category on the preferences dialog and uncheck "Left click to go forward one page; right click to go back one page".
There are other controls on this page that may be useful for you.
If this is something that needs to work on other computers, where you don't have access to the preferences, you can add the following line of JavaScript as a document level JavaScirpt in your document:
app.fs.clickAdvances = false;
