The Server Key Host Unknown Error?

Recently I started receiving the login error "The server's host key is unknown..." I'm not certain if a virus is creating this issue of if Filezilla is corrupt. When I login it appears that I am connecting to my server but I am concerned that just started happening.

When I use Filezilla on other PC connecting to the same site I don't get this error.

Should I be concerned?

Thank you very much for the help.

All it says is that the host key received from the server does not match the one you have stored for that server earlier. You need to check with the server people how the correct host key must look like, as it is possible that a server's host key changes.

If the host key presented to you does not match the one you got from server support, you might be connecting to a rogue server (e. g. through malware doing redirection or DNS poisoning). In that case, it's advised NOT to connect at all.
