I would either recommend going to add/remove programs to see if it is there and to remove it, or see if there is a way to click on the toolbar (if it is a toolbar) and click something on it to remove it.

That is if you have Windows--don't know much about Macs, sorry.

Also, run virus checker, and a spamware checker if you have one. DO NOT buy them off the internet--ONLY BUY THEM OFF THE NET IF IT IS A COMPANY YOU TRUST, but I would not recommend that.

Best...
