Yontoo adware - how to eliminate Buzzdock ads from Google and deceptive ads from YouTube?

Yontoo is a company that develops browser add-ons and web applications. Their products include web apps such as Best Video Downloader (a web app that allows users to download videos from YouTube), PageRage (an app that allows users to change Facebook layouts), EasyInline (an app that enables the highlighting of text and provides options to search across various popular resource sites), and many others. While the idea of enhancing your Internet browsing experience with various browser add-ons and plug-ins is valid, Yontoo apps are ad-supported and thus employ some deceptive methods to display them. For example, after installing Best Video Downloader, visitors to YouTube will notice that the ads no longer originate from Google - the Yontoo app overrides them with its own.

It is important to note that downloading YouTube videos in this manner does not comply with copyright law, and furthermore, ads shown within YouTube after installing Best Video Downloader app can compromise the security of your PC and your privacy. Some of these ads will request users to complete online forms in order to claim a scam prize. Dubious ads such as these could also result in the installation of unwanted applications or even malware.

When any Yontoo apps are installed on your Internet browsers, the displayed ads relating to searches no longer originate from Google. Yontoo overrides them with Buzzdock ads.

Note that it is not advisable to allow third party ads imposed in your browsers to replace original Google ads. If you have willingly installed Yontoo and are happy with the free services, then no action is necessary, however, be cautious when clicking ads displayed in YouTube and Google. If you are concerned about your computer's security and your own privacy, remove this app from your PC. Use the removal guide provided to help eliminate Yontoo from your computer.

Most commonly adware or potentially unwanted applications infiltrate user's Internet browsers through free software downloads. Internet users should know that nowadays most of free software download websites are using download clients to manage their freeware download process, unfortunately some of the mentioned download clients don't properly disclose the fact that advertised browser plugins or toolbars will be installed together with the free program that users have decided to download.

Download clients and installers that are used to distribute adware commonly hide the “decline” button that can be used to opt-out of installing the advertised potentially unwanted applications. Some of the malicious free software download websites doesn't allow to download the chosen freeware if users decide to decline the installation of promoted software. Notice that the safest source for downloading free software is it's developers website. Screenshot of the free software download clients that are used in Yontoo adware distribution:

IMO Firefox shouldn't allow add-ons to be installed without you knowing (and there's a setting for that that apparently doesn't work in the case of Yontoo)... note also that AVG didn't detect Yontoo, either.



I think there's a special place in Hell for these people that write spyware/adware, tight next to the telemarketers.....

I noticed my computer doing stupid things and ran Spybot-SD, which found some of it.

I allowed Spybot to remove what it could but later I noticed that my right-click menu in Firefox had a lot of extra crap in it (it was huge) so I started looking and Yontoo was in the add-ons (I had noticed my browser had crashed and then when I restarted it there was a message about checking add-ons for compatibility)

Spybot claims that Facebook installs it without your knowledge and I think that must be right as I didn't have any problems until I visited Facebook a couple of days before. I had Flash Video Downloader Youtube Video Downloader for several weeks before this with no problem.

I removed Yontoo from the Firefox add-ons but also ran this uninstaller I got from the Firefox support page someone had posted and between uninstalling Yontoo from the add-ons and running the uninstaller my computer seems to be working normally now.

after all, I manually deleted every file containing any reference to those three, i deleted all registry containing their names and short forms of names. after id did this, my sound system seemed to work better than before, probably because the malware was disabling surround sound for some reason.
since kaspersky can't find anything, that's all the proof i have of my success.

is it possible to REMOVE yontoo from firefox without uninstalling firefox its self? i have bestvideodownlo ader on firefox (OSX 10.6), but i can't see anything of yontoo in the addons. is it "hiding" or just incompatible with the mac version of the browsers?

i've noticed yontoo in my firefox browser (on windows 7) a few days ago.
I probably caught it, as i installed Bestvideodownlo ader or some mp3 converter from Dvdvideosoft. since i always pay good attention to what can optionally be installed with the programs; I don't think it is any use unchecking the boxes, for it was installed without my knowledge.

the weirdest of all things is this:
my up-to-date kaspersky internet security 2013 never detected anything or warned me at all. about an hour before i noticed yontoo, i was redirected by conduit, when i tried to google. after all, i noticed there was yontoo, browser manager and conduit installed to my computer.
i should add, that of these three, only browser manager was listed in the control panel.
