I got a pop up that says, CDPFOLLOWUPExtention on my MacBook Air. What password are they asking me to enter?

Hey victor1958,

If this pop up alert is not familiar to you, it would not be advisable to trust it as it may be a phishing tactic.

If this appears in Safari on your Mac, use the guidance from About pop-up ads and windows in Safari to help block those.

If you see pop-ups on your Mac that just won’t go away, you might have unintentionally downloaded and installed adware (advertising-supported software) or other unwanted software. Certain third-party download sites might include software that you don’t want along with the software that you do.

If you think that you might have malware or adware on your Mac:

*Update to the latest version of macOS. If your Mac is already using the latest version, restart your Mac. macOS includes a built-in tool that removes known malware when restarting.

*Check your Applications folder to see if you have any apps that you don't expect. You can uninstall those apps.

*Check the Extensions tab in Safari settings to see if you installed any unnecessary extensions. You can turn extensions off.

If you continue to see advertising or other unwanted programs on your Mac, then we recommend that you contact Apple Support directly so that they can work with you to find a solution. You can reach them by clicking here: Apple Support or calling the most local number in your region: Contact Apple for support and service Thank you for participating in the Apple Support Communities.
