Hi,
This is probably being caused by a third-party program- possibly legitimate-
possibly malware.
From ControlPanel> Internet Options> Programs> Manage add-ons, disable
add-ons. If that helps, re-enable add-ons one at a time to see if the
troublesome add-on shows itself.
Next step...
Startup in Safe Mode.
http://support.microsoft.com/default.aspx?scid=315222 If the problem goes
away, a program that didn't load in Safe Mode is causing it. Look at
security/privacy programs, ad-blockers, etc. to find and disable the program
or it's troublesome feature.
Or, this might be a malware problem (adware, spyware, hijackers, etc.)
