Ciao, ci risiamo, non riesco a finire la scansione con Avira, l'ultima risale all'8 gennaio, ogni volta che ci provo, dopo circa un'oretta si blocca il pc e debbo forzare per spegnerlo.
:o(
Io intanto posto il log di Hijack This
Grazie

invece di forzare la chiusura .... che ti può compromettere il computer ... prova a vedere quale o cosa ti fà bloccare il programma con ctrl+alt+canc ( ad esempio )

eventualmente fai la scansione in modalità provvisoria forse ti elimina il problema dello stop pc

prova a fare una scansione http://security.symantec.com/sscv6/default.asp?productid=globalsites&langid=it&venid=sym

ciao e buon lavoro :O)

Come mi hai suggerito ho fatto la scansione in modalità provvisoria, ma arrivata al solito punto la scansione si è bloccata.... fortunatamente il pc no.
Ho anche provato a fare la scansione con Malwarebytes' ed anche questo si è bloccato alla solita cartella.... C:Windows\$hf_mig$\KB97445-IE7\update\branches.inf ... ma che accidenti c'è lì dentro?
Che soluzione mi resta?
Formattare?
NOOO! Vi prego, ditemi che c'è dell'altro.

Attendi R16 e non ascoltar le voci dei ... falsi profeti.

Ciao.
