I started using a new firewall (Sygate) and it says an application named NDIS User Mode I/O Driver (file name ndisuio.sys) keeps trying to access my computer. I googled the term, but I'm not sure whether it's good or bad. I see the Microsoft site has info on it, but I'm still not sure what it does. I don't get all the technical jargon. I have it blocked for now.

Hello PCIlliterateGal,

From what I remember when I was using that firewall, it relates to wireless adapters. Are you connecting via wireless or cable?
Also if you open control panel right click on the adapter you are using and select properties. What is listed in the scrolling box?

No, I use DSL. I'm not sure what an adapter is, so I guess I don't have one.

The NDIS User-Mode I/O Driver component provides the NDIS (Network Driver Interface Specification) User-Mode I/O driver in the ndisuio.sys file. This driver is an NDIS protocol driver that supports user-mode access to send and receive Ethernet frames over a network adapter.

If you are able to use your DSL service, trust me you have a network adapter. I would allow this to have access.
