Ciao a tutti
nel tentativo di scaricare un pgm per rimediare a un guasto sulla pendrive, mi si sono aperte una miriade di finestre con malware e altro che mi hanno cambiato l'accesso a I.E.
Ho subito scansionato con HiJackThis - Malwarebytes - ripulito la cartella prefect - rirpistinato il sistema ad un punto di ripristino precedente, ma ho il dubbio che qualche traccia sia rimasta

mi date una occhiata al LOG -- il S.O. e' WS seven 64bit

Il log è a posto, hai solo un sacco di programmi in avvio che non servono, rallentano solo il pc, hai anche tutte le utility della Toshiba che creano solo confusione e di utile hanno ben poco.
Ciao

Ciao, ti rispondo un pò in ritardo. Io eliminerei le voci sotto.
Ho visto ora che hai attivato il Tea timer di spyBot, devi disattivarlo, crea problemi.
Disattivalo così:
Apri SpyBot in modalità avanzata (menù modalità - avanzata) poi vai in utilità - resident e togli la spunta a TeaTimer, e riavvia il pc.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked:

Tutte queste voci disabilitano solo l'avvio automatico i programmi non vengono toccati.
Se proprio qualche voce di dovesse interessare la puoi sempre ripristinare in HJT c'è la cartella Backups dove vengono salvati.
Per la chiavetta per ora non saprei cosa consigliarti, faccio qualche ricerca ed eventualmente ti aggiorno. Ciao
