Thank you for asking here! The function you would like to remove is Trend Micro Toolbar, which provides safety rating (e.g. Safe, Dangerous, Suspicious, Untested, etc) to websites that you are trying to visit and blocks known infected websites. Moreover, once you access those untested websites (marked in question), our servers would scan them automatically for analysis and assign a rating in the future. It is not recommended to disable it permanently.
If you do not want to see the website ratings directly in pages you're browsing, there's another option to rate URLs when you move your mouse cursor over the URL. Hopefully this setup will keep your pages clean while still getting protection by our advanced URL filtering engine. Please see the screenshot below to change the Trend Micro Toolbar's setting to "Rates link on mouseover":
