Alpha Networks' Wireless Zero Configuration Service Loader. This is the driver for the wireless PCI, PCMCIA (PC Card), or USB network adapters made by the Taiwanese OEM manufacturer Alpha Networks Inc in which, at the time of writing, 29-May-2005, D-Link is a major shareholder. As an OEM manufacturer Alpha Networks designs and manufactures connectivity products for other companies to put their own badges, branding, and packaging on those products. This means that you will find this particular driver installed by the installation CDs of a number of wireless brands, amongst them : AT&T, Blitzz, Cellvision Systems, Conceptronics, D-Link, and U.S. Robotics.
Exactly in laymans terms, are you installing ?
That Dlink number is a Router. Not an adapter.
From a 'very' quick web search. That .dll looks like it is used by prism chipset wifi adapters which I assume you already have installed.
It has nothing to do with spyware.
