My computer was recently hacked which resulted in me having a virus that took regular screenshots. When trying to find where the screenshots were going, I did a search for all png files on my Mac. There I noticed that there were tons of images generated by Evernote of the 'cards' you'd see in Card View. Even though I use always Snippet View, previews of all my notes appear in a readily accessible directory on my Mac deep within the Library. Because I had previously stored passwords in Evernote, I realize now that these screenshots contained the user/pass of every password, making the info readily available outside of the Evernote application and easily found by a spotlight search. Is there a way to prevent Evernote from creating these graphics? It seems like a major security issue for anyone who uses it to store secure info. I'd have to stop using it if there's no way to turn them off.
