For some strange reason when I tried to install the update several times. One time I saw a message saying it was a portable version and the installation location was not recommended.
I went to delete the current installation and could not find it listed in Add and Remove in the control panel nor in Revo Uninstaller. So instead of updating I went to the main download page and downloaded from there.
The download went smoothly and manually deleted the old Dragon link on the desktop. I was surprised that the install did not see the Comodo Dragon file underr Program Files nor the old link, and then remove and update with the latest version.
Never noticed before that under Search Engine Mangagement Yahoo listed
Just wondered what disadvantage is it to use the Comodo DNS for everything?
