Ciao.
Se dicevi a cosa si riferiva quell'errore era meglio.
Avvia in modalità provvisoria http://guide.aiutamici.com/guide?C1=7&C2=68&ID=80122
Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su fix checked
O4 - HKLM\..\Run: [5b6ce1a7] rundll32.exe "C:\WINDOWS\system32\qiqnjaui.dll",b
Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
*********************************************************************************************************
Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.malwarebytes.org/
Prima di fare la scansione AGGIORNALO.
Esegui una scansione completa del sistema
Posta il log.

Ciao
Infatti, se noti, la voce che ti ho segnalato indica proprio quella dll.
Comunque prima di eliminarla definitivamente (l'ho solo tolta dall'Avvio) aspetto il log di Malwarebytes.

Contento lui.....
Se quella dll fà parte come sospetto (per questo volevo vedere il log di Malwarebytes) del troyan Vundo, che se la tenga stretta...........metterà sù una bella famigliuola.
Ciao!
