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?
