I accidentally installed some weird buttons on my Google toolbar and I can't remove them.?

these buttons are not on the list of available Google buttons. they look like a magnifying glass. when I type something in Google search box, each word I type pops up on the toolbar with this magnifying glass button next to it. I tried uninstalling the Google toolbar and then reinstalling it , hoping these buttons would disappear, but they didn't.|||sounds like a possible virus, try this site, http://delete-virus.com
