Ciao a tutti,
avrei bisgono di aiuto visto che il mio fido avast! da qualche giorno mi bombarda di messaggi.
In più all' avvio di Windows mi appare un messaggio del tipo "Il programma è stato chiuso per facilitare la protezione" Le opzioni sono: Chiudi il lessaggio oppure Operazioni da eseguire, l'ultima delle due però non dà alcun risultato, così non si apre Windows e mi rimane solo lo sfondo del Desktop ed il Task Manager. Sono riuscito a fare ripartire il sistema non so come visto che mi si presenta lo stesso messagio anche in modalità provvisoria.
Altra cosa... si aprono spesso pagine di explorer non richieste, visto anche che uso firefox.
AIUTO!
Vi posto anche il file di log.
Grazie a tutti.
