It can come bundled with other softwares or are installed without the knowledge or consent of the user. It may track the browsing habits and search queries of the user which then can be sent to its server so that advertisements can be displayed accordingly. It can launch on system startup and has the capability to download its own updates. It can also install other programs on the user’s system. It may result in browser slow down which decelerates the browsing experience of the user. Hence, the user is advised to remove this program from his system.
