can't deleat dictionary boss/mindspark from my computer

I mistakenly downloaded Dictonary Boss / mindspark tool bar on my laptop and now I can't get rid of it .
It dosen't show up on my list of programs in control panel . It does show up on the start menu in my computer check up . when I open the file from there and try to deleat it ,a message says must have admin, permission . I click continue , deleat runs to about 98% then disapears . There are a lot of files conected to this thing and I would like to git rid of all of them , any help would be welcome .

Thanks , Ron
