cannot delete any jpg images?

This is very frustrating and I'm hoping someone can help me.

The "Secure Overwrite Highlighted" and "Secure Overwrite Checked" are lightly shadowed and not responsive for any of my jpg files. Those options seem to be inactive for all my jpg's. so I cannot delete them

I've read that this could be related to them being in the mft file. Is there any other way using Recuva or any another program to get rid of them?

I've tried Cccleaner and have cleaned all the free space with mft checked off but they're still there after a Recuva scan. I'm wondering if a defrag would do it.

Any advice would be helpful. Thanks
