windows/system32 virtual device driver

Every time I turn on widows xp and run adware I keep getting a critical object under C:\windows\system32  ide 21 201.vxd.  The file vendor is Win AD and its a Data Miner. I keep deleting it but the next time I start up windows that file is back again. I think it may have to do with the Morephus (peer to peer program) which I uninstalled.

 

Can someone help me get rid of that file forever. I looked in registry but could not find any file that I could delete.

 

Thank you
