il browser si blocca dopo un pò

[Emanuele142857]

Ciao a tutti, ho un problema con i browser del mio pc (windows vista): sia che utilizzi firefox, explorer o chrome, (tutti sempre aggiornati) dopo un pò di tempo che navigo in internet (il tempo è variabile) aprendo una pagina qualsiasi mi dice "caricamento in corso" e lì ci rimane....Chiudo firefox, provo a riaprirlo, ma mi dice "il processo è già in corso", provo a chiudere il processo con gestione attività ma non si chiude, per risolvere il problema devo riavviare il pc (tra l'altro ogni tanto impiega anni a spegnersi dopo che il browser si è bloccato). Ho fatto numerose scansioni con diversi antivirus ma niente
Ho avast 5.0, zone alarm free e a-squared free (e windows defender)
Cosa devo fare per ovviare al problema?
Grazie per l'attenzione

[Emanuele142857]

C'è qualcuno che mi può aiutare?

Grazie!!!

il problema è su un portatile ?

[Conetti]

Ciao, dall'analisi del log di HiJackThis risulta un'infezione da Ad-Aware: l'applicazione sospetta è Zwunzi.
Esegui le seguenti operazioni:
1) Fixa con HiJackThis le seguenti voci:

R3 - URLSearchHook: UrlSearchHook Class - {00000000-6E41-4FD3-8538-502F5495E5FC} - C:\Program Files\Ask.com\GenericAskToolbar.dll
O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file)
O2 - BHO: Ask Toolbar BHO - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Program Files\Ask.com\GenericAskToolbar.dll
O3 - Toolbar: Ask Toolbar - {D4027C7F-154A-4066-A1AD-4243D8127440} - C:\Program Files\Ask.com\GenericAskToolbar.dll
O23 - Service: Zwunzi Service - Unknown owner - C:\ProgramData\Zwunzi\zwunzi132.exe

2) Disinstalla da Start --> Pannello Di Controllo --> Programmi --> Disinstalla Un Programma l'applicazione "Ask Toolbar" e l'applicazione "Zwunzi"
3) Esegui una scansione mediante l'antivirus e Spybot Search & Destroy, eliminando eventuali voci rilevate
4) Esegui tutti gli aggiornamenti disponibili da Windows Update e verifica, dopo il riavvio del Pc, se riscontri ancora i problemi precedenti.
Fammi sapere

[Emanuele142857]

in realtà sono già disinstallati, sono rimaste solo le voci, infatti ho seguito la tua procedura e mi ha detto che non esistevano piu

[Conetti]

Ora come procede la situazione?
Per eliminare interamente le voci dell'applicazione, dobbiamo cancellare le Chiavi di Registro create.

[Emanuele142857]

Ho seguito la procedura ma non è cambiato niente, i browser si bloccano ancora....
