All respect to Brundle but there is a simpler way. Uninstall anything to do with AOL on your computer. Reset the router AOL supplied you with by pressing the small button next to the power socket for a few seconds. Wait until all the lights stop flashing. Now open up your browser (IE,Firefox,Opera,whatever) and type 184.108.40.206 into the top search bar. When asked the user is "admin" and password is "password". Enter the info as requested. Scroll to the bottom of the list on the lefthand side and logoff.
I'm a bit confused here. If you're using an ethernet modem or modem/router then you're already connected to the net. No need for AOL's software just any browser. If you're connected via usb modem then right click the AOL icon in system tray, click AOL dialler, enter screen name, password and auto sign-on if required. Then use any browser. You'll only need AOL's software installed if using an USB modem.
