grazie in anticipo

Ciao 65maria
Il log è pulito.

Prova questo programmino nuovo di zecca (per me) che elimina le versioni Java obsolete, è anche in italiano:
http://www.friulinews.it/modules.php?op=modload&name=News&file=article&sid=3175&mode=thread&order=0&thold=0
Poi elimina queste voci di hijackthis:

Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
Provvedi a svuotare del suo contenuto la cartella Prefetch :


clicca su Risorse del Computer
clicca su Disco locale C:
cerca, all’interno delle cartelle che saranno visualizzate la cartella Windows, aprila ed, al suo interno, cerca la cartella Prefetch, la apri ed elimina tutte le voci conservate al suo interno ( non eliminare la cartella)
SVUOTA IL CESTINO
Hai il file-system NTFS ?

Allora fai anche questa operazione (con calma, che nessuno ti corre dietro):
lancia Hijackthis
clicca sulla voce Open the misc tool section
clicca su Open ads spy
togli la spunta alla voce Quick scan (windows base folder only)
lascia la spunta alla voce Ignore safe system info streams
togli la spunta alla voce Calculate md5 checksum of streams
clicca su Scan
se venissero rilevati ADS, spunta tutte le caselline e clicca su Remove selected
Devi riavviare il sistema.

ok r16 ho fatto tutto ciò che mi hai detto è tutto a posto, nel senso che nn sono apparse caselline ads

r16 sembra che adesso funzioni tutto bene, ti ringrazio infinitamente

ti ringrazio moltissimo
