Hi dash1730,
Norton is not intended to block these kinds of programs. As the screenshot posted by intesec shows, Malwarebytes detects this as a PUP, a potentially unwanted program that, the removal or keeping of which, is optional. PUPs are considered to be only potentially unwanted because they do offer some legitimate service or benefit, such as a special toolbar, in exchange for the annoying ads or intrusive tracking that users consent to when they install the program. In most cases these PUPs install as additional piggyback software when you install another program that you want. It is important to read each screen whenever you are installing or updating anything on your PC, because the consent to include the PUP, and to let it do whatever is stated in its EULA, is usually preselected by default. It is up to the user to pay attention and to opt out of anything presented in the installation that is unwanted. Programs like Malwarebytes often detect PUPs and other grayware, whereas most traditional AV programs do not, since PUPs generally install with the user's permission and there is no way of knowing if the permission was granted knowingly or not.
