    I had this problem. I had uninstalled the comcast toolbar, but it left the comcastantispy.exe, what should I do?

    Please use crtl-alt-del to access the task manager then clicked the process tab and browsed through until you found Comcast Antispy. exe. And then right clicked it and selected “open file location” and inside the folder there was the program along with an uninstaller. Use the uninstaller and it should be removed.

    Fix options 1 through 4 worked for me except that the folder in my computer was labeled “comcasttb” (two T’s). It’s located under program files, for those who don’t know. I didn’t continue with option 5.
