Agent not picking up McAfee Last Scan Date

I am finding that the inventory scanner is not bringing in the Antivirus Last Scan Date under the Security tree for the computers running McAfee.  We are running a mixed bag of Symantec and McAfee.  Works on Symantec but not on McAfee.

Supposedly this is determined by the LDAVHLPR.DLL

I am currently running version 9.0 SP4 with plans to go to 9.5 SP1 but we won't be there for a while.  Does anyone know if this data does come in with version 9.5 SP1 and if I can just steal the LDNAVHLPR.DLL and use it with my version 9.0 SP4 for this?

Regards,

Bradley
