NT Kernel and Sysytem message - what does it mean?

About once an hour I get a little window that pops up in the lower right corner of my computer that gives the above message.

It cannot be clicked and goes away on its own after about 10 seconds.

WTF is it and how can I make it stop? It makes an annoying little “bloink” sound when it pops up.

Thanks bunches!

I suspect that your computer is infected with a virus or trojan horse. Naming an application “NT Kernel and System” is the sort of thing a cracker would do to try to make his program look like a normal part of the system.
