errore RUNDLL dopo scansione con nod 32

[eziosaccoccia]

ciao a tutti..la mia ragazza si e' ritrovata con il pc piena di virus e troian...
usa panda AV..vedendo che c'era qualche evidente problema che il panda non riusciva a trovare....gli ho fatto provare il nod ...che gli ha cancellato un file infetto..(C:\WINDOWS\sistem32\yjyrajkx.dll)
e ora quando avvia il pc esce una finestra di errore:

RUNDLL

Errore durante il caricamento di C:\WINDOWS\sistem32\yjyrajkx.dll

impossibile trovare il modulo specificato





qualche anima pia puo' aiutarmi a rimediare?

grazie

probabile che rundll.exe era stato settato per eseguire quella dll. posta un log di hijackthis

Rifai la scansione con hijackthis, selezioni le caselle di queste righe e premi fix checked.
Controlla ed elimina il file in rosso se è ancora presente.
