Applications that are executed by default when your Mac is starting up are known as Login Items. The list of these objects includes important system processes and programs that you want to be launched automatically every time you boot the system. All in all, this is a great way to customize your computing and save yourself the trouble of running most-used apps manually. The shady side of the matter is that Login Items have recently become an element of adware attacks. A potentially unwanted application such as IdeaShared may mishandle this feature by configuring the compromised system to trigger the offending executable at boot time. To remove unwanted default (login) items from your Mac, go to the Finder and select System Preferences. Go on to Users & Groups and click the Login Items tab. Select the entity you want to delete from your startup apps and click the minus icon (“-”) to stop it from automatically running when you log in.
