Chrome keeps getting this demand to update something

Here is the web site, which downloads a file

Google Chrome Browser Extension Update

It wants me to click on it and install an update for an extension.


So what is it, Is it dangerous?

I found out it is freetwittube, something I did not install, so I removed it.

something called yontoo.

I also have some real player extension which I did not install.

looking at how to remove yontoo, suggestion came up spyhunter4
SO it has found hundreds of potentially bad infections, including yontoo.

Run of Malwarebytes shows nothing.

I found ccleaner free can remove the tracking cookies.
Yontoo I removed from the uninstall programs part of win7

That left only a fragment of Claro and yontoo mentioned in some config files.

ok, here it is

don't see anything like browser manager in programs.
Don't have any claro troubles.

I am using google Chrome Remote Desktop to access this PC. Works well.
I am upstairs and it is downstairs. I access it using an Ubuntu PC 12.04

It is easier to sit here to work on it as the downstairs PC with windows is attached to a TV.
