why am i getting a prompt to sign in to iCloud?
Recently I began to receive a prompt on my iPad that asked that I "sign in to iCloud." Below that it further stated "Enter the Apple ID password for 'my user name'. When this first appeared it seemed innocuous because I was able to 'Cancel' the request and it went away. Now it will not go away. I have tried shutting the iPad off and then back on and the prompt will not go away. This strikes me as virus like activity, as before I have had no problem accessing the cloud with Pages and Numbers without signing in. What is going on here?
iPad 2, iOS 7.1.2
