ho seguito le indicazioni, tra l'altro il file sde.dll, riesco ad eliminarlo (provvisoriamente) solo terminando il processo rundll32,
mentre pbocdll non riesco a toglierlo in quanto mi dice essere in uso da windows<font color=red></font id=red>
ringrazio fin d'ora per ulteriori consigli
ugo

E' inutile che ripeto la risposta, segui le indicazioni della risposta precedente, da eseguirsi passo passo e sopratutto le rimozioni da Hijack This e la cancellazione dei file devono farsi in MODALITA' PROVVISORIA

Inoltre devi installare il programma firewall indicato.

Fai inoltre una scansione antivirus on line da questo indirizzo
http://security.symantec.com/default.asp?productid=symhome&langid=it&venid=sym
se dopo la pulizzia la scansione rileva virus, l'unica cosa da fare e formattare il disco e reinstallare tutto.
