What Are PUAs?
PUAs (Potentially Unwanted Applications) are a type of malware that can cause unwanted alert notifications, display unwanted pop ups or ads, or even install unwanted applications on your Mac. They are typically found within your web browser and might be unknowingly bundled with other free software you download off the Internet. Once installed, they will begin to appear repeatedly until removed.

Remove Malicious Software
After scanning your Mac with VirusBarrier, you'll want to check for any remnants of the malicious applications which may be left behind.
Open a Finder window and navigate to Applications:
Find and Remove Adware or Malicious Software
Look through the list of Applications to locate the software to delete. Once you have found the adware, right-click and select 'Move To Trash'.
A few examples of adware you might find include Mac Cleanup Pro, Dock2Master, WeKnow, Shlayer, Spigot, SurfBuyer, MacSaver, ShopperHelper and CrossRider. (Note: This is not a complete list of all known adware, and the names of these malicious programs change constantly. The name of the application you need to remove on your Mac may differ from this list.)
Empty the Trash from your Dock to completely remove the application from your Mac, then restart your computer to complete the process.
Uninstall Adware Extensions From Your Web Browsers
In addition to scanning your Mac with VirusBarrier, you'll also want to check all of the web browsers you use to see if there are any extensions installed for adware. There are plenty of browsers available for macOS, but we're going to cover the three most popular choices in this article: Safari, Chrome and Firefox.
Delete Unwanted Extensions
Some adware will also install extensions in your web browser which allow them to display ads and pop-ups for potentially unwanted programs and services. You'll want to remove these from your web browser if they exist by using the Uninstall or Remove command.
Location: Safari > Preferences > Extensions
Location: Chrome > Settings > Extensions
Location: Firefox > Settings > Extensions & Themes
Disable Website Notifications Within Web Browsers
Some PUAs will also install notifications from within your web browser which allow them to display ads and pop-ups for potentially unwanted programs and services. You'll want to remove these from your web browser if they exist.
