Ciao ,
esegui queste operazioni

1) Disattiva il ripristino di configurazione, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=257&SH=N

2) riavvia in modalità provvisoria, leggi qui come fare
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=344&SH=N

apri HIJAC THIS ed elimina come indicato in questo articolo
http://www.aiutamici.com/software/descrizione.asp?CodSw=1175
le righe che seguono, (nel caso le righe da eliminare non compaiono in modalità provvisoria, eliminale dalla modalità normale e riavvia il computer).

-
O4 - HKLM\..\RunServices: [Norton Personal Firewall] lah.exe
O4 - HKCU\..\Run: [Norton Personal Firewall] kah.exe
==================================

Con la funzione TROVA di Windows, cerca ed elimina questi file,

==================================
lah.exe
elitedbj32.exe
zdablpu.exe
newsd32.exe
shch.exe
kah.exe
==================================

al termine utilizza i programmi AD-AWARE e SPYBOT indicati in questo articolo
http://www.aiutamici.com/software/view.asp?tipo=home&CodSw=388&SH=N

sempre in modalità provvisoria fai una scansione Antivirus

quindi riavvia il computer e controlla se il problema e risolto, se e tutto OK riattiva il ripristino configurazione disattivato all'inizio di questa procedura.

Prova a cercarle nelle cartelle, se non li trovi forse erano create al momento dal virus e poi eliminate, ma non dovrebbe essere per questi file.

c:\windows\system32\zdablpu.exe
C:\WINDOWS\newsd32.exe
C:\WINDOWS\shch.exe

comunque anche se sono presenti ma non caricate dal registro non sono pericolosi, occupano solo spazio, i virus sono comuni programmi che devono essere eseguiti per compiere le loro azioni.
