- Adware Cleaner
Congrats on hopefully having removed your adware with Adware Cleaner! Now that you’re Mac has been restored, you’ll probably want to prevent any more adware coming back.
The most effective thing you should do right away is navigate to Settings -> Security & Privacy. Click the Lock icon at the bottom and then switch your setting on the bottom to allow apps downloaded from “Mac App Store” or “Mac App Store and identified developers.” 
Now when you try to install anything that isn’t in the App Store or an identified developer, you’ll get a pop-up message that says it can’t be opened.
Another useful tool is installing an AdBlock extension for your web browser to prevent popup ads.
