Salve a tutti chiedo umilmente il vostro aiuto QQ
Navigando su internet ieri pomeriggio improvvisamente firefox si è bloccato causando un ravvio non voluto del pc. Da quel momento tempo 15 20 minuti il pc si inchioda, le scritte della barra di avvio diventano simili a quelle di win98 (ho xp) e dal case esce quel continuo e fastidiosissimo BIP obbligandomi a resettare per riavviare tutto. Ho scansionato con Avira, spybot, ccleaner, antimalware ma pur trovando qualcosa il problema non si risolve. Allego il log di hijack sperando possiate darmi una mano a risolvere dato che ora come ora è completamente inutilizzabile il pc (è la quarta volta che cerco di scrivere sto post...mi si impalla sempre Q___Q) Grazie mille.

ciao muddy

volevo chiederti un paio di cose..... la prima e' se hai provato vedere se firefox si comporta cosi' anche in safe mode

la seconda domanda e': hai ancora installato il programma Bywifi nel pc?

intanto segui questa procedura

scarica questo file zip,
http://www.mvps.org/winhelp2002/hosts.zip disconnetti il pc, estrai sul desktop dal file zip solo il file Hosts, selezionalo, tasto destro del mouse, copia, poi apri la cartella C:\Windows\System32\drivers\etc\ in un punto libero fai incolla, accetta la sostituzione del file hosts esistente, potrebbe darti errori non preoccuparti, riavvia il pc.


Scarica e installa malwarebytes
http://www.malwarebytes.org/mbam/program/mbam-setup.exe
Aggiornalo: clicca sulla scheda "aggiornamenti" => "controlla aggiornamenti"
Esegui una "scansione completa" (seleziona l'opzione)
A scansione completata, posta il rapporto e per ora non rimuovere niente
