		Goto control panel, open programs & features, you will see some names regarding this, if you don't, remove the things which you don't know. Also check the extensions in your browser.

		You have virus on your PC.
Check your extension and removed what seems to be the virus (unknown extensions)
Open program manager and uninstall what you don't recognize.
Also run anti-virus and tracking the installation folders can be useful too.
