Da quasi tre settimane ricevo il messaggio:
Generic Host Process for Win32 Services o svchost.exe.
Subito dopo la barra del desktop appare come se il PC fosse stato riavviato in modalità provvissoria e molte icone vengono modificate. Visto che ho l'ADSL non succede niente alla connessione, ma si mette in modalità non in linea. Ho provato diversi anti malware e antidialer ma nessuno ha riscontrato nulla.
Ho visto che ci sono diversi post che trattano l'argomento, ma non mi sembra di aver trovato indicazioni a carattere generale.
Per anticipare inserisco il log di HJThis: spero di aver letto bene le indicazioni generali del forum e di non avere sbagliato includendolo nel post.
