I went to your link and "Acrobat WebCapture Cookies" doesnt exist. I gave up there and had someone remote in from Adobe. He had me uninstall Acrobat, but what I realized is: it's not enough to press "uninstall" through creative cloud. Because doing it through creative cloud doesnt actually unstall it. It was still sitting in the applications folder. I had to go into the applications folder and click the icon "Acrobat Uninstaller" which is listed one above the normal Adobe Acrobat application.
