Forefront Protection for Exchange hotfix rollup 1 (FPE RU1) and Forefront Protection for SharePoint (FPSP) utilize version 5 of the Kaspersky engine by default. However, both products have the ability to use version 8 of the Kaspersky scan engine.
To enable Kaspersky 8, copy the localenginemapping.cab to the following location ( …\Program Files (x86)\Microsoft Forefront Protection for Exchange Server\Data\Engines\metadata). The settings will take effect automatically. The next engine update will provide the Kaspersky 8 engine.
