Your antivirus program is wrong. |app| is a completely open source product. You can actually browse the source code yourself (or hire someone to do it for you) to verify that it is not a virus. Please report the false identification to whatever company you buy your antivirus software from. If the antivirus program is preventing you from downloading/installing |app|, disable it temporarily, install |app| and then re-enable it. +How do I backup |app|? +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The most important thing to backup is the |app| library folder, that contains all your books and metadata.

First, you must authorize your reader on a windows machine with Adobe Digital Editions. Once this is done, EPUB books transferred with |app| will work fine on your reader. When you purchase an epub book from a website, you will get an ".acsm" file. This file should be opened with Adobe Digital Editions, which will then download the actual ".epub" e-book. The e-book file will be stored in the folder "My Digital Editions", from where you can add it to |app|.
