Salve,

da qualche giorno ogni volta che apro Chrome e mentre ci sto navigando Avast mi mostra periodicamente queste segnalazioni di URL infetti senza anche se sono pagine che non ho aperto io. E mi parte anche la ventola per qualche secondo (non so se è direttamente correlato, ma porterebbe)



Non mi pare che accada anche con Internet Explorer.

Uso Windows 7 su un portatile Toshiba.
Vi incollo qui il log di HJT.
Ho fatto una scansione con l'ultima versione di Malwarebytes, ho eliminato le minacce che ha trovato ma il problema persiste. La "scansione intelligente" di Avast non mi ha trovato nulla, ma aspetto di risolvere questo problema per cambiare antivirus perché ormai Avast è diventato troppo invasivo.

Spero possiate aiutarmi,
Grazie mille.

Ciao e benvenuto.

Segui le indicazioni di questa guida:

Tralascia Malwarebytes, se lo hai eseguito, ma posta il log della scansione.
Posta i log richiesti nelle modalità descritte a fine link.

Ecco i log

Ciao.
I vari tool hanno eliminato parecchie infezioni, fra cui un pericoloso Trojan.
Riscontri ancora problemi?

[angelword]

Ora sembra di sì. Ma risulta qualche altro trojan o malware dai log oltre a questo che hanno cancellato i tool?

[R16]

[angelword]

Fare la pulizia con CCleaner del registro intendi premere su "Trova problemi" nella voce Registro e poi "Ripara selezionati"?

[R16]

Sì.

[angelword]

va bene grazie mille

[R16]

Prego.
Se riscontri qualche problema, torna pure qui.
Ciao.

Ciao,
purtroppo il problema mi si è ripresentato, Avast mi continua a segnalare accessi a questi siti (con avvisi come si vede nello screenshot nel primo post che ho messo) quando navigo su Chrome.
Ho rifatto tutta la procedura con i tools di rimozione, per un giorno è stato quieto poi ha ricominciato.
Ho fatto una scansione completa con Avast ma non mi ha rilevato nessuna minaccia.

Cosa posso fare? Aiuterebbe disinstallare Chrome e poi reinstallarlo di nuovo?

Stavo pensando anche a formattare Windows per tagliare la testa al toro ma vorrei evitarmi lo smazzo del formattone.

Grazie

[R16]

Ciao.
