i have similar problem. i have installed a software named SecurKeeper but its seem its bugged my whole system and now i cant delete it or uninstall it cause its always say access denied.. i tryed several trick to gain own control over it but i cant seem to be able to. any hint?
Have you tried disabling UAC? Also try changing the user permissions on the folder and then try deleting it.
try dsabling UAC. if that doesn't work you can restore your pc to a time before you installed the bugged software, use ''System Restore'' to do this!
