Well, I have confused myself on this! The "normal" Chrome icon to the internet (the red, yellow and green circle with blue circle in the middle) with the words Chrome below the circle is the one used for several years. This is the one "locked up" with the message you have won an Amazon gift card for $1,000 (giftcardhd.tom). This message can't be deleted nor can you do anything except click the "OK" on the message which I have not done. I had to shut the tablet down but when restarting and clicking the chrome app icon the lockup is still there. After restarts with no luck clicked on the "G" app icon on the tablet apps screen. It has been on the apps screen all along but have not used before. It is a white background circle with the "G" in it with word Google listed below it. I was on the Montana owners website when the lockup gift message appeared using the "chrome" icon. I clicked the google "G" and got back to the Montana site. This icon when clicked lists the sites I had been on using "chrome" from tablet along with other sites visited before the lockup. I clicked on Montana site and got back to it. I will continue to see what else can be done with this "google" icon. Internet searches using my desktop PC says you can not remove "chrome" from an Android device. It is factory installed and an Android product. I have tried and cannot do anything to remove, deactivate or whatever. Thanks
