There is a lock symbol on the Spybot icon in my taskbar. When I tried to uninstall in add/remove programs, I received the error message unins001.msg is missing. I updated to 1.6.2 and tried again to uninstall and received the same message. Then I went to program files and tried deleting Spybot there. I received the message Cannot delete advcheck.dll: Access is denied.
What should I try next?
