@Berny No I haven’t. The NAS is in the local network. As I said earlier, I have no problems accessing it via windows explorer. I can browse the path both via X:\ as a mapped network drive or as \\nas\directory\ In both cases, I am able to create new directories, files and and modify or delete them. So I don’t understand why Kaspersky can’t access it. What is even more strange, is that Kaspersky can see the network drive and also navigate through the subdirectories, but still sys incorrect path. There is also no information about this error message on the internet.
