How to get delete email?

How do you get rid of a conversations file when no delete option is given in your email menu for it?

• I have two email addresses one for anything personal and my social networking and the other I use for official work etc. However, with my social networking email through yahoo since October 2011 I have had a new file that I didn't create on the side menu. You know inbox, conversations, drafts, sent, trash and spam. the conversations box is the one I shouldn't have and I don't know how it comes that I have it. I thought it came with the New update that Yahoo underwent but if that were so my other email address would have this as well. I have taken a brief look at one of the emails and they seem to be from dating websites. Dating websites is something I don't do, so how come I am receiving these emails. To give you a little bit more detail the words of the texts are all in different colours. I also notice that yahoo advertising is taking longer and longer to upload on each page and the other day there were two columns of ads relating to dating websites rolling down my screen as I was typing my emails to be sent. The least I thought I'd be able to do is delete this extra file I have. But when right clicking no option to delete appears and there is also no option to delete with a left click. What can I do to get rid of this file? Also if I switch off cookies will this ruin my rmail account?
