Google search engine results returned in Yahoo

I use the Google search engine to search the Internet.
In the last couple of days the days are suddenly returned by the Yahoo search engine. I suspect this is a Comodo setting because the results url is: http://search.yahoo.com/search?p=google%20help&ei=UTF-8&fr=chrf-comodo
How do I get rid of this setting? If I search using Google I want the results in Google. Same with Yahoo

Hi TimTDP,
Which browser are you using?

This has happen to me and 2 other users I know.

I am using IE
Firefox
COMODO Dragon
Chrome

all of them are effected.

I am using the latest versions of Firefox and Internet Explorer

In Firefox,
Type about:config into the address bar continue I will careful, I promise!
In the search field type keyword.url, right click on the result and choose reset.

In Internet Explorer,
Go Tools, Internet Options, Search Settings, choose your desired search provider and make default.
Alternatively go to the link below to add new search providers.

In Dragon/Chrome,
Go to Menu, Settings, Search, Manage search engines.
Hover over your desired search provider and make default.

done that. Results still get returned in Yahoo

Hi TimTDP,
Is this with the search bar or the address bar?

If it is with the address bar make sure the reset keyword is similar to below, %s - Google Search
Also make sure the keyword.enabled is set to true.

search bar

Does the following help?
Search bar Firefox
