Ciao a tutti, dopo aver avuto diversi attacchi ho necessità di sapere se ora il mio pc è a posto (almeno come virus!) poichè permane ancora il problema che il sistema non riesce a rilevare le unità ottiche installate. Ho provato ad aggiornare i drivers ma la risposta è che non ce ne sono di più aggiornati.
Seguendo poi le discussioni e il parere degli esperti sul forum (Monsee e altri) ho installato Malwarebytes, Avg-antirootkit e Avg8free, quale Firewall è il più indicato con questa combinazione (nel caso comunque abbia capito bene e sia corretta...)
Grazie
Vi posto anche il Log di Hijackthis per il controllo :

Vanno bene i seguenti firewalls:

in lingua inglese:
COMODO Firewall Pro (scaricabile da Aiutamici)

in lingua italiana:
PC Tools Firewall Plus (un po' più semplice da usare per un principiante; scaricabile da Aiutamici);
GoldTach Firewall 3.3 (il più "leggero", ma affidabile; scaricabile anche da: http://ilgiggiotto1.altervista.org/index.php/Protezione-PC/Firewall/Antiintrusione/GoldTach.html );
Online Armor 3 Free (scaricabile dal sito: http://www.tallemu.com/free-firewall-protection-software.html );
Sunbelt Personal Firewall (dopo l'installazione, per 30 giorni, non potrai più loggarti su Aiutamici; dopo di che, potrai nuovamente farlo; scaricabile dal sito: http://www.sunbeltsoftware.com/Home-Home-Office/Sunbelt-Personal-Firewall/ ). ATTENZIONE: l'antivirus Avast! mostra la pervicace tendenza ad aggredire immotivatamente questo firewall: per cui, NON si può installare Avast! e questo firewall sul medesimo computer.
