Innanzi tutto grazie per la celere risposta! Ho fatto tutto ma dalla scansione on line risulta ancora infetto il pc e non sono riuscita ad eliminare la dll
posto il nuovo log magari c'è qualcosaltro da eliminare!

Ciao, il file 723103432.dll non c'è più, in compenso sono comparsi due fetecchioni che peggio di così non potevi incontrare. Parlo di <font color=red>spoolw.exe</font id=red> e di <font color=red>igfxsvc.exe</font id=red>. .

Scarica <b>VirIt</b>, aggiornalo e fai una scansione in madalità provvisoria. Il tool dovrebbe riconoscere il <b>trojan.win32.small.LQ</b>. Se sei fortunato, dovresti risolvere, altrimenti dovremo adottare altre procedure.

Pubblica il report di VirIt.

NON SO PIU' COME RINGRAZIARTI!!! HO INSTALLATO VIRIT E GLI HO FATTO FARE UNA SCANSIONE. QUI SOTTO TROVI IL REPORT. SPERIAMO BENE!

Ciao, come vedi <b>VirIt</b> ha fatto un ottimo lavoro. <img src=icon_smile.gif border=0 align=middle> Adesso posta un log aggiornato di HijackThis.

---

Ciao, il log è pulito.
Devo dire che sei stata fortunata, perchè è la prima volta che questo trojan è stato polverizzato col solo aiuto di VirIt.

Aggiorna il Java. Il link te l'ho indicato nella mia prima risposta.

---

Certamente, il Nod32 è uno dei migliori antivirus in circolazione, l'ho avuto anch'io a suo tempo, poi mi sono innamorato dell'AVG.

Senti, ho fatto un po' di casino in un post sopra, ho modificato involontariamente una risposta che non era destinata a te, poi per riparare ho messo un puntino. In questo forum non è concesso cancellare i post.
Ciao e sorry
