It looks like you may have Mcafee's site advisor installed and maybe this could be the cause of the registry problem.
Uninstall Mcafee Site Advisor if its on the system and run ccleaner click here and reboot.
You could always reinstall Mcafee SA if you so desire.
If the problem persists,try running Winaso regopt version click here leave this on its default setings,it is a trial version and will correct any 10 errors at any one time-though you can rescan and repair as you like.
If still no joy,post back and we can look a little deeper.
