Another negative aspect of PUAs is that they are often designed to collect browsing-related data such as IP addresses, keystrokes, search queries, URLs of visited websites, and so on. Furthermore, clicking these ads might lead to other untrustworthy websites or execute scripts that download and install other PUAs. These can be very annoying and affect the overall browsing experience, since they are usually displayed via tools that enable placement of third party graphical content on any site and conceal underlying content of visited websites. Potentially unwanted applications that cause redirects to these deceptive websites also tend to deliver intrusive advertisements - coupons, banners, surveys, and other similar ads. In any case, do not restore the closed session the next time you open the browser, since this will open an identical/deceptive website or the website that led you there in the first place. Another way to close it is to simply restart your computer.

If you cannot close it normally, use Activity Monitor and terminate the entire browser process.
