Hi, kovidgoyal, I just installed Calibre. It seems to work well enough. However, in the middle of reading a book Online Armor flagged that the calibre-parallel process wanted to run and in fact wanted to install a keylogger. What's it all about? I wasn't doing any conversion; I was just reading a book--and at the moment that the calibre-parallel process wanted to run wasn't even reading the book but working with another program.
