I get the same message sometimes. It never seems to have any serious effect on my computer either. I have got AOL though, and am pretty sure the WAOL message is something to do with it. Are you sure you don't have AOL somewhere in your computer? They are notoriously sneeky at hiding their software in systems, so even when you think it is uninstall, there is something still there. I don't think it's anything serious to worry about, but do a virus/spyware check just in case.
