User account control shows "Publisher: Unknown" for File Operation
Hello. My computer recently (less than a day ago) started to display User Account Control prompts whenever I deleted or copied that weren't in the "Users" folder, such as the Program Files folder. I am using an Administrator account, and the User Account Control is set to notify when programs make changes to Windows but without dimming my desktop. Whenever I try to delete any type of file not in the Users folder, the User Account Control prompt pops up like in the attachment. I believe there is something wrong with the "File Operation" program, because I'd imagine it would be signed by Microsoft and would automatically be elevated to Admin status so the prompt shouldn't show in the first place. Clicking on "Change when these notifications appear" doesn't do anything, but I am able to copy/delete files after clicking "yes".
I'd really appreciate help, because it's getting annoying getting this prompt whenever I want to delete or copy a file, and this prompt never appeared before when I was just deleting a file until a day ago. I'm using Windows 7. I'm just using a Windows 8 RP theme. Also, I don't want to disable UAC, since it lowers security.
I feel perhaps something happened to that certain registry key or keys related to it. But I'm not sure.
EDIT: I figured out that something was wrong with shell32.dll, so I replaced it with an unmodified copy of the file from another computer and the prompt doesn't come up anymore.
