Ogni tanto, ormai da un paio di mesi, norton mi avvisa della presenza sul computer di un virus, tale downloader, dicendo che è impossibile da riparare e che 'laccesso al file è negato. Io non avverto problemi particolari, ma dovrò pur far qualcosa ? Attendo vostro benevolo interesse

P.S. quanto ancora potrò andare avanti con norton 2005, mantenendo un livello di sicurezza decente ?

Cosa sono gl'indirizzo che inziano con one - res://c:/.... ?

Hai installato -volutamente- qualche programam per qualche protocollo speciale?

[sabatino]

canon, riguardano la stampante. Google toolbar, li ho sempre avuti, e non li ho ritenuti pericolosi.....
ora disinstallo questi ultimi semmai !

[Smjert]

Il log è pulito.
Ma ti dice esattamente quale file trova infettato? e come lo classifica?

[sabatino]

mi dice solo che ha rivelato un virus, Downloader, e mi nega l'accesso al file. QUindi non so. Ma un Downloader che tipo di virus è, pubblcitario, dialer, o peggio ?

[Smjert]

Ha il compito di scaricare altri malware...

Prova a farti una scansione online con Panda (disattiva momentaneamente il controllo real-time di Norton).
Posta poi il risultato della scansione.
