Unwanted popup offering free download of YouTube videos I have watched

Ev77 · 15 Oct 2018

I am getting lots of pop-ups like the attached .jpg offering a free download of something I watched on YouTube. This can happen even when no browser is running. I have searched the web and can't find any references to this. I find lots of references to "Free YouTube Download Manager" but this seems very different. I do not find anything obvious that I can uninstall. TaskManager also shows nothing obvious (to me).

I watch YouTube videos via Firefox. I have only installed the LastPass add on. Sometime after watching a video, I get a pop up like the attached one.

How can I remove this?

Many thanks for any help.

PUP run Malwarebytes should get rid of it.

Download ADWCleaner scan, Clean and Restart, then follow it up with Malwarebytes Free, scan and Quarantine.

Thanks for your reply & the good suggestion. Unfortunately, ADWCleaner scan followed by Malwarebytes did not discover or stop it.

Process Explorer has a tool that you can use to identify which process is causing the popup.

You don't need to install it (simply run the exe file).

Drag the crosshair over the popup and release it.
The process should be highlighted in the process list window.
