I discovered the "Yontoo" extension was causing major issues and was extremely surprised to find it in "programs and features" on my control panel! It wasn't the only surprise installation discovered either "delta toolbar" had appeared out of no where too. Neither extension were on there by my choice one was a download extension and the other was a security extension.

I was just going through the EULA and found this that should be made aware of: "Once you have installed Yontoo Layers, each time you load or refresh a page in one of the Yontoo supported browsers, a request will be made to a Yontoo owned server to determine whether or not you have enabled any Services for the domain you are currently browsing. Yontoo may collect and analyze your usage patterns such as which sites you visit, that are not personally identifiable. These non-personally identifiable data are used to improve Yontoo’s services, and may be shared with third parties."

Every single web page I go to in IE popups the yellow bar on top states "this website wants to run the following add-on "Yontoo Layers Client for Internet Explorer" from "Yontoo Technology, Inc, (unverified publisher)". Is this a virus or something? I ran a bunch of adware removers and Spybot S&D identified it as Adware/Yontoo.Pagerage and by Avira anti-virus as Adware/Yontoo.A.13. Also, I beleive it is related to Drop Down Deals as when it was installed it also created a folder called Drop Down Deals in Program files.
