Q: how do I eliminate o malware popup

Force Quit Safari ( command + option + esc keys). Then, Relaunch Safari holding the shift key. Then, turn off Safari extensions (Safari menu > Preferences > Extensions)

If that doesn’t do it then…

Then restart Safari holding the Shift key. From your Safari menu > Clear History and Website data. Then go to Safari >Preferences > Advanced and checkmark Show Develop Menu and empty caches. Restart Safari.

Click here and follow the instructions in the first paragraph of the last section.

Thanks Niel, completely missed the iOS. Doh!

Are you using Safari or Google Chrome? If Google Chrome try deleting the app, a forced restart, and reinstalling Chrome.

Forced Restart. Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. You will not lose anything.
