Please I need help.

[Fran Ildefonso]

 
My PC is infected with a called virus W32/tweener.A@bd and I don't get to remove it. I make Scan and Avast doesn't detect.  
But it informs that that virus is resident in an executable one: located d?dplay.exe in the folder System 32 of Windows NT 2000.  
If somebody can help myself  
 
Thank you

First you say:

I make Scan and Avast doesn't detect.

Than you say:

But it informs that that virus is resident

Is it detected by Avast or not?
And what is telling you the name of the infection?
The major av companies don't know a malware called tweener.

That's an F-prot/Frisk/F-Secure detection
