Yahoo takes over

I updated Comodo firewall yesterday and ever since, if I type something in the URL search bar, instead of going via Google, it will go straight via Yahoo.
I have problem with Yahoo for years and am avoiding it by all means.
I did Google redirect virus cleanup, just in case, I have all search engines, besides Google, disabled or deleted via Mozilla options and IE tools.
Anything else I need to do? Now, if I use right hand search engine bar in Firefox, it all goes through Google, but I sometimes forget and punch "bank of america" into the main url search bar. Then it goes through Yahoo.
It may sound like "no big deal, dummy, just use Google" but I have almost burnt myself about 6 mths ago, when Google search/bookmark saved brought me to a phishing site.
I caught it on time, called BOA to report, and they told me to use url search bar from now on, bypassing Google search in the main screen.

 

Definitely Comodo's doing
look at the url:

Code:

[url]http://us.search.yahoo.com/search?fr=ytff-comodo&p=bank+of[/url]

has both Yahoo and Comodo in it. Guess, I'll shoot them email.

 

Well, like I mentioned in my original post, I did redirection clean up, along with some other things.
I, also, posted same question on Comodo forum. They kindly told me that Comodo is now making small comodians in same bed with Yahoo (or is it comohoodians now?), to "cover for free firewall expense", hence redirections.
