Security Warning for Playstore site

I have had this happen to me but on my Samsung Tablet but these instructions are going to be the same. Type in Google play support and put your device name in spot where it asks for your devices model number and then they will have detailed instructions on how to reset google play to factory settings. If this method does not work then backup everything you want to keep and restore your device to factory settings. If you can't get to the actual site try the app and if that doesn't work then you could have your security settings set to high.
