Le site search.yahoo.com est-il sûr ?

I had / have a yahoo email. yahoo decided to sell or send my information to others. I contacted yahoo and ask them not to do this. yahoo told me they would do it anyway. I went elsewhere, setup a new email then went back to yahoo and told them I wanted to cancel my yahoo email account. yahoo said NO! From time to time my yahoo email pops up to annoy me, I have not used it in many years and never will!!

This is specifically directed at: http://search.yahoo.com/?ei=utf-8&fr=tightropetb&type=11423_043015 This cannot possibly be a well intentioned Yahoo search function. This site forcibly imposes itself over any existing homepage you might have, and persistently reverts any attempt by the user to change it. This is a function of adware. It's suspicious, and disingenuous.

It hijacks a site i'm trying to visit, a normal site nothing dodgy (*****) and redirects me to this DNS error yahoo search, i even click on one of the search options relating to iftn.ie and it redirects me again to a DNS error yahoo search. It does this to a few sites i try to visit and it bugs the absolute shit out of me and i'm sick of it.
