I downloaded a MSPL.cab file. The software company said its a bridge between IE amd MS Project software. Our IT security people don't trust it and need proof its actually a valid MS file and that its not malicious or phishing or hidden trojan..etc. The only components I found of this is MSPL.ocx and MSPL.inf, Icould not locate the original MSPL.cab file in my hard drive.

Software/Hardware used:
IE Ver 8 and MS Project 2010
