[OT] Invalid host address

This kind of gibberish: 
<http://iamlinux.technoyard.in/blog/getaddrinfo-1-invalid-host-address-ignored-ntpd-errors-in-syslog/>

I do understand in general what it's talking about, and I know about the 
computer hosts file and how it can be hijacked, but what I really need 
is a recipe to send to an unsophisticated user who needs to fix the 
problem. We suggested malware to him but he says the problem is only our 
app. He says he looked at some console logs (OS X) and it showed a 
timeout, though the return error my app displays is "invalid host address".

Thanks for any info anyone has.
