è da qualche tempo che mentre uso msn, mi arrivano dei messaggi strani con dei link con una faccina sorridente da alcuni amici, e contemporaneamente credo che io stesso li invii ai miei amici, e molti mi dicono che potrei avere un virus!
Ho Avg come antivirus, ma nonstante ripetute scansioni non mi trova virus, solo degli avvisi che poi ripulisce in atomatico! Chiedo aiuto a qualcuno di Voi, vi chiedo grazie anticipatamente!

Salve dawson82,
le consiglio come antivirus di usufruisce Avast Home Edition, molto buono per qualsiasi tipologia di virus, a riguardo il log che ha postato le posso dire che deve fixare i seguenti passaggi:
1°O2 - BHO: (no name) - {02478D38-C3F9-4efb-9B51-7695ECA05670} - (no file);
2°O2 - BHO: (no name) - {5C255C8A-E604-49b4-9D64-90988571CECB} - (no file);
3°O3 - Toolbar: (no name) - {0BF43445-2F28-4351-9252-17FE6E806AA0} - (no file).
Perché essi non necessari (disattivati) dovrebbero essere eliminati. Questa voce è stata classificata totalmente sicura.
A questo punto la consiglierei di scansionare il suo Windows Live Messenger con questi due software, che risolvono una buon media di virus presi da Msn...LiveKill Clean Messenger & MSNCleaner.

Grazie a tutti dell'aiuto!

Per superromu: Io non sono proprio espertissimo, per mettere il LOG ho seguito la procedura che veniva spiegata qui sul sito nella pagina dove ho scaricato i lprogramma!
Se non ti è troppo disturbo potresti spiegarmi la procedura per fixare i passaggi da te indicati!
Grazie!

Salve dawson82,
certo si figuri, non c'è nessun problema per fixare i percosi da me sottolineati, basta spintare con il puntatore una "v" accanto al percorso e cliccare sul pulsante "Fixare".

Salve cbbusto,
la ringrazio dei complimenti e del pensiero non coerente con il mio a riguardo il miglior Antivirus che sia Avast Home Edition, ritengo che ogniuno abbia il proprio pensiero in base ale proprie esperienze.
