Il problema che ho avuto (e che a dire il vero ultimamente non lo fa più) è il seguente:
dopo un po' che ho avviato il pc compare una mascherina con scritto in alto Norton Internet security. Il testo della mascherina dice: "40exmodul32.f.m.exe sta tentando di accedere ad internet. Cosa fare?" Poi consigliano di accedere ad internet. Se io accedo mi compaiono le mascherine di scansione messaggi e poi un'altra più grande con scritto Microsoft Visual c+Runtime library. Runtime error! program c/programmi/file comuni/Symantec shared/ ccapp.exe
R6025
pure virtual function call
Come dicevo è un po' di tempo che non lo fa più ma gradirei per sicurezza una controllata al log.
Grazie

ciao ,
allora fai cosi:
Disconnetti il pc e disattiva il ripristino config. di sistema
(Vai su Start--->tasto destro del mouse sull'icona Risorse del computer----> Proprietà .Nella sezione "Ripristino configurazione di sistema",spuntare "Disattiva Ripristino configurazione di sistema)
Avvia il computer in modalità provvisoria
(Riavviare il sistema--->Immediatamente al termine del caricamento del BIOS premere ripetutamente il tasto F8 fin quando non appare il menu Opzioni avanzate di Windows--->Vai su Modalità provvisoria e premi Invio)

Assciurati di avere accesso a cartelle e file nascosti
(Pannello di controllo---> Opzioni Cartella ---> Visualizzazione--->metti la spunta su"visualizza file e cartelle nascoste"--->disattiva nascondi file e cartelle di sistema)
Fai uno scan con hijackthis e fixa queste voci:
O4 - HKLM\..\Run: [.nvsvc] C:\WINDOWS\system\smss.exe /w
O9 - Extra button: (no name) - {85d1f590-48f4-11d9-9669-0800200c9a66} - :windir:\bdoscandel.exe (file missing)
O9 - Extra 'Tools' menuitem: Uninstall BitDefender Online Scanner v8 - {85d1f590-48f4-11d9-9669-0800200c9a66} - %windir%\bdoscandel.exe (file missing)
O9 - Extra button: MUSICMATCH MX Web Player - {d81ca86b-ef63-42af-bee3-4502d9a03c2d} - http://wwws.musicmatch.com/mmz/openWebRadio.html (file missing)
Tutte le voci con 018 tranne la penultima e la terzultima.
Poi cerca ed elimina questo file:
smss.exe--->attento a non confonderlo con il processo leggittimo di windows che si trova in---> c:windowsSystem32smss.exe
Fatto questo dai una ripulita con Ccleaner--->prima vai in opzioni--->avanzate--->togli la spunta elimina files temp solo se piu vecchi di 48 ore

Ritorna in modalità normale,riattiva il ripristino config.di sistema e posta un log aggiornato

Grazie mille!! Non vorrei però essere antipatico o ingrato ma il tuo nick non corrisponde a quelli elencati nella pagina che spiega l'utilizzo del software Hijack this. Fammi sapere qualcosa.
Grazie e ciao
