MacSecurityPlus prevents Mac users from closing Google Chrome and, as with virtually all adware, also feeds them with various pop-up ads, coupons, banners, surveys, and other unwanted items. Note that most people download and install adware-type apps unintentionally. Like most potentially unwanted apps (PUAs) of this type, it delivers intrusive advertisements and gathers information relating to users' browsing habits.

One adware-type app known to cause this issue is MacSecurityPlus. This tutorial will show you how to browse as a guest in Google Chrome by opening a Guest mode window.If the Google Chrome window (browser) keeps reopening after closing, it might be caused by an adware-type application present on your computer. You'll see your info and settings without saving any browsing history. If you want to browse privately on your own computer, use Incognito mode.

If there's a supervised user on your computer, Guest mode isn't available when all non-supervised profiles are locked. If you sign in to an account to use a web service (like Gmail) while in Guest mode, your browsing activity might be saved on sites that recognize that account.
