Con avenger, clicca su input script manually e poi sulla lente di ingrandimento.
Nello spazio bianco inserisci con copia incolla tutta la parte colorata in rosso:



files to delete:
C:\WINDOWS\winlogon32.exe
C:\windows\syss.dll
c:\0afdc47fd7ac8997259433\mrtstub.exe



clicca su done.
poi sul semaforo con luce verde
due volte si, il pc si riavviera' e al ritorno posta il log di avenger (C:/avenger.txt).

[accatiemmeelle]

prima magari aspetto che finisca lo scan online di bitdefender o lo interrompo per farlo con avenger?

[accatiemmeelle]

aspetto che finisca lo scan di bitdefender prima di fare questa cosa con avenger?
ha analizzato 50000 file su 166500 circa... oppure lo interrompo e passo subito a fare questa cosa che mi hai detto con avenger subito??

[OYS]

Aspetta che finisce.

[accatiemmeelle]

ha finito la scansione di bitdefender ma non so come farvela vedere visto che la salva in html e gli allegati che si possono inserire sono solo di tipo immagine... ora provo la procedura di prima con avenger però vorrei farvi vedere anche con bitdefender

[accatiemmeelle]

ecco il log di AVENGER
