I need to rename these kaspersky related files for force installation

Question

Dear Community,

I was having issue with lastest kaspersky Version. I couldn't uninstall it as after installing the kaspersky the machine would only boot in safe mode. then i raised a support ticket and asked kaspersky to help me. They asked me to do following:
"

1. Try to rename klam.sys to klam.sy_ and then try to boot again.
2. In case if at some point KES was installed there then do the same for klflt.sys "

Now what is happening that I still cannot rename one particluar file, the snapshot is attached.

When I try renaming it, it gives me this error. I am a domain Admin but I still cannot rename this one file.
Kindly help me withh this.
