File Name Warning for C:\Program

Since a few weeks I get the error message after login:

File Name Warning
There is a file of folder on your computer called "C:\Program" which
could cause certain applications to not function correctly. Renaming it
to "c:\Program1" would solve this problem. Would you like to rename
it now?

[ ] Don't perform this check at startup

Clicking the Rename button results in the error message

Folder In Use
The action can't be completed because the folder or a file in it is open in
another program
Close the folder or file and try again

Therefore I started Process Explorer and did a Handle search for C:\Program. Of course it finds a lot of items for C:\Program Files and C:\Program Files (x86), so I sorted them by name. There is no handle listed for C:\Program.

Next I assumed it might be a permission issue and tried to take ownership of the folder. Unfortunately this does not work as well. I get

 Error applying security
 An error occurred while applying security information to:
 C:\Program
 Access is denied.

followed by

Windows Security
Unable to set new owner on Program.
Access is denied.

The current owner is the administrators group and I am a member of that group. Checking the effective permissions, I have full control (all checkmarks checked). I can create files and delete files inside the folder.

There are no files inside the folder, neither in Explorer nor DOS (dir /a) nor Search Everything.

Some websites say I have malware, but I doubt that. I'm not visiting dangerous websites and I have an up to date virus scanner.

How do I delete the C:\Program folder?

Note: I don't have access to the BIOS, so can't boot from a CD drive or USB stick.

I know that I could disassemble the PC and connect the hard drive to a different PC, attach it as an external drive and then make changes to the disk. However, I'm looking for a built-in solution.

Solution 1:

Have you tried booting into Safe Mode to see if it makes a difference? This should help rule out third-party programs and shell extensions that could could be interfering.

To use Safe Mode, restart your computer and hold F8 just before Windows starts to load.

Solution 2:

It could possibly be McAfee access protection keeping you from deleting the folder C:\Program\

1. Disable Access Protection.
   • Click Start, Programs, McAfee, VirusScan Enterprise, VirusScan Console.
   • Right-click Access Protection and select Disable.
   • Leave the Console open.
2. Delete the folder C:\Program\
3. Enable Access Protection.
   • Click Start, Programs, McAfee, VirusScan Enterprise, VirusScan Console.
   • Right-click Access Protection and select Enable.
   • Close the VirusScan console.
