Can IE Companion enable me to deactivate browser pop ups?

Hi people.
I have been terribly pissed with pop ups whenever I am working on Internet Explorer. This keeps happening even when I am building a blog online using WordPress. I sincerely don't understand what these advertisements and other related pop ups are. I have been advised to try IE Companion with the promise that it will resolve this. Do you believe that? Have you ever tried it? Does it really work impeccably? Thanks.
