Safari is locked on my iPad.

iDevice Safari Phishing Adware Pop-ups

Your device does not have a virus. You can fix this as follows:

Kill Safari by double-tapping on the Home button. Locate Safari in the task bar, then slide the Safari mini-page upwards so it vanishes.

Tap Settings > Safari > Clear History and Website Data. Next, locate Security section and slide the “Block Pop-Ups” switch to the On position.

Press the Home button to return to your Home screen.

If this doesn’t help, then reset your device. It won't delete your data. Press and hold down the On/Off button and the Home button until the display turns off and returns with the Apple logo showing.

Alternatively, follow these instructions to reset your device: Restart your iPhone, iPad, or iPod touch - Apple Support.

The suggestion worked.....double click on home button, then slide "safari" page off screen. I am back in control of my iPad. All other functions had worked before I was locked in Safari----Ibooks, for example. Thanks for the help.
