Been getting lot of errors over the past couple of week with the Kaspersky engine not updating:
Log Name: Application
Event ID: 6012
Task Category: Engine Error
Microsoft Forefront Protection encountered an error while performing a scan engine update.
Scan Engine: Kaspersky
Error Code: 0x80004005
Error Detail: Description: An error occurred while loading the scan engine.
The resolution works a dream:
Under C:ProgramData there is a folder called "KasperSky SDK" (you will have to enable viewing of hidden files to see if)
Rename the folder to say it for example to "KasperSky SDK,old”
Update "Kaspersky" through the Forefront Console
