Yes, you are using McAfee 8 and have not patched it for a long, long time.
Patch it, upgrade it or disable checks for buffer overrun.
If you are not using McAfee, then you most likely are not setting the text
in the MessageBox properly and need to show us some code before we can
help you.

Happy Coding!
