1) Sulla barra delle applicazioni mi compare l'icona di avviso di protezioni windows che evidenzia un errore. Aprendo il 'centro di sicurezza windows', noto che compare in rosso il segmento di 'protezione da malware'., come se non ci fosse nessun programma antivirus istallato. Io utilizzo Avast e fino all'altro giorno questo er tranquillamente contemplato. Un giorno fa ho fatto l'aggiornamento di vista SP2 ...... qualcuno ha avuto lo stesso problema e se si come ha risolto?

2) Sempre sulla barra delle applicazioni l'icona di 'windows dwfwnswe' awgnala l'anomalia come se il programma non fosse aggiornato riportando la dicitura 'verifica la disponibilità di nuove definizioni'. Eseguo l'aggiornamento ma non mi viene trovato nessuna definizione da installare mal'errore non scompare. Questo problema compariva anche prima dell'aggiornamento ad SP2.

Grazie 1000 per tutti i suggerimenti.

Ti posso portare come esempio la mia situazione, dovrebbe esser così anche per te.
