With Adobe Reader XI 11.0.03 Update Adobe has introduced Signature field detection feature, which upon finding ‘sign’ or ‘sign in’ words in a PDF document automatically displays green bar on top with message “Signature field detected” and prompts to “open Sign Pane”. Unfortunately this version is wrongly detecting and showing green bar even though there are no signature fields in a PDF file, Adobe is aware of this.

Meanwhile you can quickly hide this message by clicking on the icon on left of message bar or you can disable Signature Field Detection feature using registry editor, so that you won’t get that annoying green bar again and again.

You’ve to wait for Adobe to improve the accuracy for their signature detection feature as well they should provide an option to get rid of that message than using registry method which we’re explaining below.
