Can I Delete NetGroup Packet Filter Driver

[mjd]

Hi All,

When I boot up my PC, I keep getting the Found New Hardware Wizard window, saying the wizard will
help me install software for NetGroup Packet Filter Driver. It says "What do you want the wizard to do?" -
- Install the software automatically (Recommended) or
- Install from a list or specific location (Advanced)

I always keep hitting Cancel on the wizard. But of course the Wizard keeps popping back up
everytime I boot up.
Question#1:
How can I stop this Found New Hardware Wizard from popping up everytime at boot-up?

Futhermore, I don't know if I need/want the NetGroup Packet Filter Driver.
I think it may have gotten loaded during my recent battle with viruses.
(That's a whole 'nother story I'll probably be asking about later).

In Device Manager, I can see NetGroup Packet Filter Driver listed under Other devices.
I can see I have the file BCMWLNPF.SYS on my system in C:\WINDOWS\SYSTEM32\DRIVERS
but I don't see the npf.sys file anywhere.

Question#2:
Do I need this NetGroup Packet Filter Driver for the proper running of my PC or can I delete/uninstall it?

(I have a Dell Inspiron 9100 laptop, running Windows XP Home edition, SP3).

Appreciate any and all help from the wise people on this forum.

Thanks.
