[Resolvido] &nbsppc lento - virus aparentemente removidos

Boa noite!

Estou tendo problemas no pc. Ele esta lento.

Desde q o Avira 2011 detectou WORM/Conficker.IH[worm] num arquivo chamado zbdondnd.dll,'W32/VB.BU' [virus]em C:\WINDOWS\system32\explorer.exe' e RKIT/Conficker.A[trojan] em C:\WINDOWS\system32\01.tmp

Aparentemente eles foram removidos.

Mas o avira continua avisando

c:\windows\system32\zbdondnd.dll

[NOTA] A entrada do registro está invisível.
