How to tell if internat.exe is legit?

Hello,
In my ZA firewall logs I see the following event for the OS firewall:
SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/RUN internat.exe
If I check for more info, I get the following:
“Host Process for Windows Tasks is trying to delete a value in the registry”
I have done a Google search, but most of the entries I see are old, 2002 – 2011.
I can not find the “internat.exe" file on my system.
I can not find the “SOFTWARE/MICROSOFT/WINDOWS/CURRENTVERSION/RUN internat.exe” in the registry.
There is a legit MS file by this name, located in SYSTEM32 according to the threads I saw, but again, I do not have this file on my system.
There are a lot of threads thru Google stating this was a bad virus/trojan a few years back, so now my question.
How can I tell if this is legit or a virus/trojan.

Win 7 Pro
Current Updates applied
I have ran the following:
Microsoft Security Essentials
MalwareBytes (free)
MBAR
Hitman Pro (paid)
AVG Rescue CD
Avira Rescue CD
All have come up clean.

Any suggestions would be greatly appreciated. (as you can tell, I am not that knowledgeable in this area)

thank you.
