The latest version of CCleaner (like the previous one) leaves one single cookie in the "Cookies to Delete" list after it has run. On one computer, it was "amazon.fr", on another one "amazon.ca". These recent versions are the first two that fail to delete everything. Do Amazon's cookies have special characteristics that make them immune to CCleaner?
Did you tick the "Adobe Flash Player" checkbox in the Applications tab ?
Yes, the box is checked.
