Ciao

Le fastidiose pagine di pubblicità durante la navigazione sono provocate da questo file: c:\users\utente\appdata\local**oggffyfa.exe
**Inoltre sei incappata in un falso programma di sicurezza:Spyware-Secure.
Segui queste indicazioni.

Tasto destro sull'icona di Hijackthis -> esegui come amministratore
Clicca su "do a system scan only"
Metti la spunta a queste voci e clicca su "fix checked"

Scarica the Avenger

Lo salvi in una cartella, scompatti il file .zip
Individua avenger.exe, lo avvii
Inserisci questo script nel box bianco

**Clicca su Execute
Il pc dovrebbe riavviarsi (se così non fosse, fallo tu)
Posta il log che verrà creato in C:\Avenger

Esegui Combofix come ti ho consigliato ed allega il rapporto.
Tasto destro sull'icona di Combofix -> esegui come amministratore

Come antivirus stai già usando Nod32, perchè comprarne un'altro?
Se proprio vuoi cambiare opta per Antivir, oltre che ottimo è pure free.

Abbi pazienza. Mi dici che devo andare con tasto destro su icona, ma se clicco su icona estrapolata da winzip non mi esci "esegui come amm...". Quindi mi dovresti anche spiegare come estrapolare icona correttamente.
Ti ringrazio. Buon appetito vista l'ora.

Hijackthis non va eseguito da cartelle temporanee.

Prima estrai correttamente l'exe con Winzip
Per decomprimere un file basta cliccare sull'icona e compare una finestra con all'interno il suo contenuto:
Cliccare su **ACTIONS e dopo scegliere SELECT ALL **cioè seleziona tutto, vediamo che i file all'interno della finestra diventano blu.
Cliccare di nuovo su **ACTIONS **e questa volta scegliere **EXTRACT **e si aprirà una finestra per scegliere dove salvare i file in essa contenuti
Se si vogliono salvare i file in un'altra cartella basta selezionarla cliccando sui segni "+" , e trovarla.

Posizioni Hijackthis.exe in una cartella in programmi
Avvi hijackthis come ti ho suggerito

Ecco il rapporto :

Ciao dialcrises,
nello script di avenger c'è stato un errore, forse per via degli errori di digitazione, comunque nulla di grave.

Error: could not open file "c:\usesr\utente\appdata\local\oggffyfa_nav.da t
c:*users*\utente\appdata\local\oggffyfa_nav.dat

Sei riuscita ad avviare Combofix?

Buongiorno.
Per quanto mi hai detto sopra, devo fare qualcosa?
