Yahoo Messenger comes with a slew of extra browser toolbars and add-ons that are difficult to delete. You cannot delete them simply by uninstalling Messenger; instead, you must uninstall Messenger, remove programs from Control Panel, reset your browser settings and clean up any straggling registry files before finally removing Yahoo Messenger and its associated files completely.
Navigate to the Messenger folder in the Yahoo folder. The default location is in Program Files, but if you installed it to another location, go there. Scroll down and double-click "UNWISE" to begin the uninstall process.
Choose "Custom" to thoroughly delete Messenger and click "Next."
Choose "Select All" to remove all of the Messenger private files and click "Next."
Choose "Select All" to remove all Messenger registry keys and click "Next."
Choose "Select All" to remove all Messenger registry trees and click "Next."
Choose "Select All" to change registry keys that Messenger edited back to the default and click "Next."
Choose "Select All" to remove all Messenger sub-systems and click "Next."
Click "Finish" to complete the uninstall process.
Go to "Uninstall or change a program" in Control Panel and uninstall the Yahoo Toolbar and Yahoo Software Update to get rid of extra applications that came with Yahoo Messenger. Restart your computer.
Open your web browser, for example, Internet Explorer, to restore your original homepage and uninstall browser add-ons that Messenger came with. Go to "Internet Options" in the Tools menu.
Either type a new homepage into the field or choose "Use blank" to reset the homepage away from Yahoo. Click "OK."(see reference 2)
Go to "Manage Add-ons" in the Tools menu.(see reference 2)
Go to "Search Providers," chose "Yahoo" and click "Remove" to remove the Yahoo search bar add-on that came with Messenger.(see reference 2)
Tips & Warnings
- If you chose not to install associated toolbars and add-ons when you first installed Yahoo Messenger, you don't have to search for and delete them. Simply uninstall Messenger and then clean up the registry.
