Is the file lph.dll a legit file by Ms for Office 2007?

[Tom]

I bought several MS Office Prof 2007 via ebay from different vendors - they
came boxed with all the expected labels, security flags, holograms and
imprints. When trying to install one, my Hips popped up alerting me to a
file.
Uploading this file lph.dll to virustotal shows that 7 out 41 AV consider
the file a trojan/malware.
I contacted MS support re the first file I received and was told that the
license number was legit but did not get any answer re the lph.dll issue.

Does anyone know what this file does, why some AV consider it malware (could
be a FP) and in particular if it is part of the official installation file
for MS office Prof 2007?

A quick web search showed that some consider it a Trojan, others a false
positive. The purpose of the dll seems to be in part to modify windows
genuine advantage.
