Hi Eliotl, Weather Blink toolbar is developed by Mindspark LLC and in most cases this toolbar installs using deceptive banner ads in free software download websites. These browser plugins can also install together with free software downloaded from the Internet. Notice that installation on this adware alters one's Internet browser settings by changing homepage and default search engine to mywebsearch.com or home.tb.ask.com If you can't use the uninstall option from your Control Panel use this removal guide which shows how to eliminate Mindspark toolbars directly from one's Internet browsers (Internet Explorer, Google Chrome or Mozilla Firefox).
