Il mio pc ultimamente mi dà dei problemi. A volte funziona normalmente, altre volte dopo che l'avvio, non riesco ad aprire nessuna applicazione, non mi fa cliccare su nulla mentre la freccina continua a muoversi.

Riporto i risultati del Hikacklist..spero possiate aiutarmi.

Grazie

http://forum.aiutamici.com/yaf_postst96025_eliminare-pagine-pubblicitarie-e-porcherie-varie.aspx

ciao a tutti
stefffffy (meno f no' vero? ) allora vedo che fax ti ha dato consigli e fidati è jventino ma fidati ciao fax( a proposito conta i tasti magari uno lo ha preso lui ) se non risolvi fixa queste voci
C:\Program Files (x86)\NetRatingsNetSight\NetSight\nielsenonline.exe
C:\Program Files (x86)\NetRatingsNetSight\NetSight\nielsenonline.exe
compare due volte
C:\WINDOWS\SysWOW64\cmd.exe
e scusa sono perplesso su questo" Platform: Unknown Windows (WinNT 6.02.1008)" mi puoi spiegare se vuoi perchè il sistema operativo è sconosciuto?
Non ti preoccupare non è mia intenzione giudicare ma casomai se posso darti una mano ciao

ciao stefania

entra in modalità provvisoria ( f8)
disinstalla crome .... e poi fai pulizia con ccleanear

spegni e riaccendi ..... e riporta nuovamente la scansione con HijackThis

---

ciao
fax Platform: Windows 7 SP1 (WinNT 6.00.3505) questo è quello che vedo sul mio w7 64 bit, se vuoi dire che hij non è più attendiblile su S.O superiori a xp ok ma per il resto, cmq se stefffffy dice che il pc funzia ok, di dubbia origine devi svelarlo tu io ho postato quello che hij mi dà tu hai solo sviato la ricerca , cosa hai installato sul pc?
Se ti riferisci a questa "\nielsenonline.exe" contenta tu contenti tutti
ciao

Salve
i log:
fai copia e incolla.
Tanto poi qualsiasi cosa la puoi cancellare col tasto edit,
idem se sbagli a scrivere
Saluti

Altra info, è normale che tra i processi attivi ve ne sia uno che si chiama: fsavailux e che occupi il 100% del disco?

Grazie :))))))))))

@black tu mi hai suggerito di fissare nielsen.exe? Ma se è un programma attendibile?
Invece devo fare qualcosa in merito a "cmd.exe"?

Ieri come se nn bastasse si è avviata l'analisi ed il ripristino di c! Che sta succedendo?
In merito all'articolo che mi hai fatto leggere..nn dice molto..cosa vorrà dire?
Non posso rischiare di perdere il pc questi giorni...

Non c'è un altro modo per evitare di disinstallare Chrome? Ho tutti i preferiti installati.
Vorrei evitare di aggiornare ad 8.1 perchè ho paura di perdere qualcosa, mai come ora non vorrei perdere nulla dal mio pc, per una decina di giorni almeno.

Altra cosa, in ccleaner alla sezione di avvio devo disattivare anche i processi pianificati e quelli del menù contestuale?

Grazie come sempre...ce la farò prima o poi a ripulirlo!

Salvare i preferiti di Chrome è molto semplice:
Apri Chrome.
Fai clic su Menu Menu in alto a destra.
Seleziona Preferiti e poi Gestione Preferiti.
In Gestione Preferiti fai clic sul menu "Organizza".
Seleziona Esporta Preferiti e li salvi in Firefox
I preferiti verranno esportati da Chrome sotto forma di file HTML, che potrai poi importare in un altro browser.
Quindi elimini Chrome fai la pulizia con Ccleaner compreso il registro poi lo reinstalli e importi i tuoi preferiti da Firefox.
Per importare i preferiti/segnalibri, procedi nel seguente modo:
Apri Chrome sul computer.
Fai clic su Menu Menu in alto a destra.
Seleziona Preferiti e poi Importa Preferiti e impostazioni.
Seleziona il programma che contiene i preferiti da importare.
Fai clic su Importa.
Fai clic su Fine.

Passare a win 8.1 è importante, puoi seguire le indicazioni di Ciocca, altrimenti fallo il prima possibile.
Concordo anche sull'antivirus, Avast è un mattone, io uso Defender che si trova in 8.1.
Non mi risulta che in Avvio ci siano i processi pianificati e quelli del menù contestuale.
Comunque le voci da disattivare sono queste che ti elenco sotto.

Chiudi tutti i programmi e disconnesso da internet,
Lancia HijackThis e clicca sul secondo pulsante Do a system scan only
inserisci il segno di spunta nel quadratino davanti alle righe sotto elencate, una volta selezionate clicca il tasto Fix checked per procedere all'eliminazione, comparirà una finestra clicca su SI per accettare e l'operazione è conclusa.
Ti preciso che eliminando le voci 04, i programmi non vengono toccati ma viene solo disattivato l'Avvio automatico, inutile......basterebbe solo l'antivirus.

Ricorda che Hijackthis deve essere avviato da una cartella a lui dedicata sul desktop. Solo così Hijackthis creerà copie di backup di quello che viene eliminato prima di apportare modifiche, così in caso di inconvenienti si possono reinstallare.

Altra operazione da fare con Ccleaner:
vai in Strumenti-Ripristino sistema, seleziona tutte le voci, l'ultima rimane e non si può cancellare, poi clic su Rimuovi.
Perchè eliminare i vari ripristini, primo perchè occupano spazio inutile poi è li che si annidano le varie infezioni eventualmente presenti nel pc.
Come già detto pulisci la cartella Prefetch.
Fsavailux.exe è un tipo di file EXE associato a Windows 8 sviluppato da Microsoft per il Sistema operativo Windows, prova a fermare quel processo e non dovrebbe succedere niente, puoi sempre riattivarlo.
Posta anche un nuovo log di HJT come detto prima.
Ciao e buon lavoro.
