I started getting the consumer surveys today. Im using firefox and its showing in the browsers add-ons. It would seem yontoo has been on the system for over two weeks, which is a bit odd (using firefox) as ive had no surveys before today. It doesnt appear in the uninstall list for me, it only shows as a single file (YontooIEClient.dll) in C:/Program Files/Yontoo/
I disabled and removed it from firefox's Tools>Add-ons.
Malwarebytes forum users recommend you try adwcleaner and roguekiller for a quick clean of unwanted malicious software, which should detect and remove yontoo. With roguekiller you only need to scan and delete the unwanted registry entries. It needs to be run as admin and with no USB devices attached.

Using adwcleaner and roguekiller is probably the best way to go about removing it if your antivirus doesnt detect it. This is what I used, adwcleaner found yontoo quite easily. Yontoo seems to have appeared for me as a result of installing jdownloader, a pointless downloading tool-someone mentioned it in a forum for software that failed to complete. I had to match jdownloaders 'date created' in 'C:\Program Files' with yontoo, as yontoo didnt appear in my installed programs list. I noticed jdownloader had alot of adult related plugins, so as if much of that content wasnt questionable enough, it probably lives on yontoo scam surveying as a result. Browsing through youtube, it would seem yontoo is included with many different types of software, such as tools to download videos from webpages - 'best video downloader' is one of the most popular programs for adding or requesting yontoo to be added to your computer, according to
