Alla fine ce l'ho fatta.. ho seguito passo passo le vostre istruzioni e vi posto il Log. Riassumo i problemi:mi si aprono pagine non richieste con Google, violazioni di accesso con Reg seeker e un sacco di hidden items con Sophos tutti riconducibili a Messenger...
Grazie per il tempo che mi vorrete dedicare.

Oltre ai problemi già segnalati, non riesco a fare la scansione con avast cleaner perchè l'applicazione ad un certo punto si chiude...poi non mi si scaricano più gli aggiornamenti di Ad ware... quando navigo in Internet ed apro una pagina sento dei "clic" in sottofondo come se contemporaneamente mi si aprissero delle altre pagine (non so come spiegarmi meglio); Di fare scansioi virus in linea, manco a parlarne... si bloccano ed Explorer viene chiuso.Il mio Antivirus (Mc Afee) non mi segnala nulla.. ho fatto la scansione in modalità provvisoria. Dal LOG postato si evidezia qualcosa che sia responsabile di tutto ciò?

<img src=icon_smile.gif border=0 align=middle> Grazie dei consigli,piano piano ho fatto tutto.. ma ho ancora problemi e li riassumo:
- sulle voci di Google mi si aprono pagine non richieste ( ma ora questo succede solo al primo clic, poi tutto si sistema da solo..Boh)
-Non riesco ad eseguire la deframmentazioni disch: compare messaggio di violatione d'accesso aun indirizzo.
-Idem per Reg Seeker
Sophos mi trova ben 62 items (rootkts?) e ogni volta che ne aggiunge uno mi segnala la chiusura di un'applicazione dal nome incomprensibile (qrqtkp.exe,rbzlq.exe ecc.);se alla fine decido di eliminarli, mi compare un avviso terroristico che se lo faccio poi Window potrebbe non funzionare correttamente e sono ..azzi miei (così mi cago addosso e desisto)

La scansione on line mi ha segnalato 5 potenziali minacce: un programmma (Adware-GameSpyArcade)che ho disinstallato e Winfixer che non so cos'è, ma mi dice che non è nè un virus nè un trojan.
Insomma ...c'è qualcos'altro che posso tentare? Vi prego non ditemi che devo formattere....<img src=icon_smile_dead.gif border=0 align=middle>
