I'm having ads injected into random pages in Firefox, such as Youtube, Wikipedia and Facebook. I know Wikipedia doesn't serve ads, so this must be some kind of adware. Below the ad appears the text "Ads not by this site." Does anyone know exactly what this is? Google isn't turning anything up. I'm currently running a spyware scan, and it's not turning anything up. For reference, here's a screencap.
i was also having these ads, and i remembered that two days ago i had installed a Codec-V it was needed to view a video online. and after removing(uninstall) that Codec-V from computer. The ads has also stopped showing right away.
try removing Codec-V program.
On my machine it was a Vid-Saver Chrome and IE add-on, after removing(uninstalling) them both it was all fine.
After reading and repeatedly coming across mentions of Codec V, I remembered I recently had installed it onto my computer when I was prompted that I needed it to stream videos on a particular website.
So I found it on my computer and uninstalled it and the problem was solved, although in my case it was Codec M.
This can also happen on Google Chrome. In my case I found and I uninstalled the extension named "I want this" which had not been there previous and that stopped the ads.
