Dragon gets ERR_SOCKET_NOT_CONNECTED on all web pages.

Dragon 31.1.0 started getting ERR_SOCKET_NOT_CONNECTED after I installed Foxit Reader v6.1.4.0217. I uninstalled Foxit but the problem persisted. I did a scan for installed programs with CCleaner. A newly installed application called PureLeads was found. I uninstalled PureLeads and Dragon resumed functioning. This did not affect IE or any other application. That may be because Dragon is the default browser. I restored my latest image in case something else was installed. Win 7 Pro SP1.
