Oulook Link goling to wrong program

When I am click on any link from this one company – it always tries to open Yahoo site builder. I thikn that is because I accidently made it do that.

BUT I can’t get it to stop. I have even tried to uninstall yahoo site builder and I can’t. (I am trying to find out how to do that).

But can someone tell me how to have the outlook link go directly to the link that is in the email. Exmample: it might be a picture of a an ad and I click on it and it should take me to the store. specific email from
