My daughter got sucked into downloading Coupon Cabin. I don’t have the energy to pursue non-solutions like:
Go to Extensions and click and drag to trash—“You haven’t downloaded any Extensions yet.” etc.
It's not malware. It's legitimate (though marginally useful) software that was intentionally installed by your daughter.
Their main site is here. When you click on the Add to Safari button, it opens the App Store to install the main app. As soon as that download is complete, it asks you to allow an extension to be added to Safari.
You can't expect to wave a magic wand to get rid of this app. You're going to have to do some manual work. Fortunately, it's easy.
1) Open Safari and then open its preferences. Click on the Extensions tab.
Uncheck the box at the left, then click the extension's Uninstall button to the right.
2) That will jump you right to the Applications folder and highlight the main app. Put CouponCabin in the trash.
3) Empty the trash. Done.
If you really want to get rid of everything, then continue on to remove what will now be dead items.
1) In your user account Library/Containers folder, put the folder CouponCabin Sidekick in the trash.
2) In your user account Library/GroupContainers folder, put the folder WMZWU4Q2GQ.com.couponcabin.couponcabinsidekick in the trash.
3) In your user account Library/Application Scripts folder, put these two items in the trash.
com.couponcabin.couponcabin-sidekick.extension
WMZWU4Q2GQ.com.couponcabin.couponcabinsidekick
4) Empty the trash.
