salve a tutti, il mio esordio sul forum è per un aiuto:
all'accensione del pc, finito di caricare il sistema operativo (xp professional) appare un messaggio di windows che è il seguente "errore di caricamento egaccess4_1064.dll impossibile trovare il modulo specificato"
qualche collega di lavoro smanettone mi dice che si tratta di un virsu, altri di un dialer.....chi mi sa dire qualcosa? Vi prego di usare un linguaggio comprensibile anche per i quasi profani :-)
Grazie per la pazienza e l'eventuale aiuto.

aggiungo il file log
