You do have adware installed, as dominic23 points out. However, that adware should only be active within Safari, and only when Safari is running, so I don&#x27;t think it&#x27;s the cause of your issues.You&#x27;ve also got a lot of system modifications installed, some of which are almost certainly the cause of the problem. I see that you have some Blackberry software installed... if you are not still using a Blackberry, uninstall that software. The same is true of the Samsung software. You will need to use the appropriate uninstallers provided by the makers of those pieces of software. Do not try to use any kind of generic "uninstall" app or any "cleaning" app that provides uninstall features. Such things do not work well at all.If that doesn&#x27;t help, look through all the various kernel extensions, LaunchAgents, LaunchDaemons and login items shown in your EtreCheck report. Try to identify the software involved for each (the names should give you clues as to the site the software came from and the name of the software), and uninstall anything you&#x27;re not using any longer. Again, the same caution applies... use the appropriate uninstaller provided by the developer of that software.
