Pop-ups are annoying little windows or messages that pop-up when you visit certain sites. They are mostly used for marketing purposes but sometimes may be used for surveys or other purposes. It is a good idea to make sure that your computer is setup to block pop-ups. To do this click on the down arrow next to the Tools button within the Internet Explorer toolbar. From the drop down list displayed, click on the Pop-up Blocker command. From the submenu displayed, make sure that pop-up blocking is enabled
