What is Imagineprime 1.0 (extension in Safari? Is it a security threat?

"imagineprime" auto installed transferring me from Mail to Safari and crashed my computer. Box came up reading "Installation Complete... The configuration process is done. To finish, press OK." The "configuration is done"? Not american english...Chinese English? or the Russians...who knows. I trashed ImaginePrime which was downloaded into my Apps folder when this happened. Not the first time I've had to trash it.

      Download EtreCheck: https://etrecheck.com/maspro  and post the report here.

      Click, “Free Download” button and then  “Click to download” button.

      Open Downloads folder, click on it to open, and then select ”Open”.

      Click on the bouncing  EtreCheck icon in the Dock.

      “Choose a problem” from the popup menu box, and then “Start EtreCheck” in the dialog.

      Click “Share Report” button in the toolbar, select “Copy report” .

      Paste the report when you reply.

It could be passing that information to an outside source. I'd remove it for more security.
