I am getting a REPEAT PROGRAM Security Alert --

Windows Driver Foundation - User-mode Driver Framework Host Pr is trying to access the trusted zone.

Identification: Unknown
Application: WUDFHost.exe
Destination IP:

Clicking on View Properties indicates the program is on c:\windows\system32\. It clearly has been allowed in the past, because it indicates "This program has previously asked for Internet access".

I've had version 8.0 for about a month and I'm not sure what to do here. I've read up on WDF on the web and I think I understand a bit of what it is, but I'm not sure why it needs to access the trusted zone and why I'm getting this alert now. Any suggestions would be appreciated.

Operating System:Windows Vista Home Premium
Software Version:8.0
Product Name:ZoneAlarm Internet Security Suite
