I used Eve too - bought it but didn't like it at all; requested a refund and after a few emails back and forth they refunded my money. Anti-plagiarism software is a waste of time - it will not provide a precise answer. It will just list dozens or hundreds of sites that have the words that are in the original document. In the end when your paper contains "hello, how are you doing today?" (for example), it will mark it as plagiarized because some other millions of pages contain the words: "hello, how, are, you, doing, today". In the end it will mark your document as 70% "plagiarized" even though it's not plagiarized at all. This software is as stupid as it gets.
