Credo di avere un grosso problema di sicurezza e dovendo accedere quotidianamente da casa alla rete aziendale, non sono per niente tranquillo.
Quando avvio il computer i programmi in esecuzione automatica sulla barra delle applicazioni non si aprono più (l'antivirus AVG 8, Spybot - Search & Destroy, Skype, DAEMON Tools Lite, il multifunzione Epson, ecc.); nel Task Manager di XP l'antivirus AVG 8 sembrerebbe in funzione, ma il Teatimer di "Spybot-S&D" e gli altri programmi non ci sono più. Ho provato ad aprire il file di registro di XP con il comando regedit in esegui del Menù di avvio ma non si apre (il desktop scompare e dopo 2 secondi riappare senza aprire il file di registro). Tra le altre cose ogni tanto quando apro una pagina web con "Firefox", qualche volta al posto del link che ho aperto si aprono pagine pubblicitarie ed inoltre il tasto sinistro del mio mouse è impazzito (non riesco più a selezionare nulla, ma funziona sempre come se facessi doppio click).
Ho fatto una scansione manuale con "AVG 8", "Ad-Aware", "a-squared Free", "Spybot-S&D" e l'Antivirus Symantec Online , ma non hanno trovato niente, poi ho seguito la vostra "guida base alla disinfezione rapida" e "MalwareByte" ha trovato diversi files, valori e chiavi di registro infetti.

[code] Nonostante "Malwarebytes" abbia eliminato diversi file infetti non è cambiato nulla. Non sapendo se l'antivirus "AVG 8" e il firewall di XP funzionano correttamente e per il fatto che non sono protetto da "Spybot-S&D", come ho gia detto prima non sono tranquillo.
Spero che qualcuno sia in grado di aiutarmi.
Ringrazio tutti.
Allego il log di "Hijackthis".
