ciao cbbusto,
innanzitutto grazie per la risposta.
allora, prima non mi è mai successo, mi viene il dubbio che sia un virus perchè pochi giorni fa ho sbadatamente installato una toolbar collegata ad un programma...

scusa l'ignoranza ma non ho idea di cosa sia HJT

aggiornamento: ho visto tramite REVO che avevo un processo chiamatto ssdl.exe che partiva automaticamente in avvio del pc.
ho fatto una ricerca in google ed ho trovato che alcuni antivirus lo classificano adwere o trojan... l'ho eliminato sempre tramite revo ma ho ancora il problema delle pubblicità che si aprono da sole.

vi posto il Log di HJT dopo l'eliminazione eseguita:
(Grazie mille ancora):

Mi devo scusare ho dato per scontato che tu conoscessi HJT.

Cerca per il momento di lasciare da parte il fai da te perchè altrimenti diventa difficile seguirti.

Come immaginavo hai uno spyware, search findeer, un programmino che va a modificare i browser, creando non pochi problemi e ovviamente ti apre pagine non richieste.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked, visto che non conosci bene HJT ti preciso che le voci 04 non toccano i programmi ma disattivano solo l'avvio automatico, inutile:

Poi vai in Pannello di Controllo>Strumenti di Amministrazione>Servizi, cerca queste voci:
LiveUpSC - SoftwareUpdService
Ssro Service (SsroService)
Ssupd Service (SsupdService)
una volta trovate fai doppio clic su ognuna e poi nella pagina seguente in Tipo di Avvio metti Disabilitato, ok esci e riavvia.

Poi fai questa scansione:
Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner
Avvialo e clicca sul pulsante "Elimina".
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui.

Dopo rifai una scansione con HJT e posta il nuovo log aggiornato..
Ci risentiamo, ciao.

questo invece è il log di HJT con cui ho rifatto la scansione

ho fatto tutto (credo),
1) hjt ed ho fixato le voci che mi hai segnalato
2) disabilitato il "tipo di avvio" dal pannello di controllo
3) elimino con adw
4) nuova scan con hjt

giusto?

ok, ho fatto tutto quello che mi hai suggerito.
dopo una prima prova le pagine sembrano non aprirsi più da sole. se ricapita nei prossimi giorni mi faccio risentire.

3 domande dovute principalmente alla mia ignoranza:
1) c'è la possibilità che questo virus abbia trasmesso dati personali a terzi (password ecc)?
2) io lavoro spesso con lo smartphone connesso al pc ed installo app ecc, c'è il rischio eventuale di un contagio?
3) mi consigli di fare la scansione con Ccleaner a scadenze regolari?

è tutto.
ti ringrazio infinitamente, è raro trovare un aiuto così cordiale e puntuale.

buona giornata

Davis

grazie mille ancora.

@lorenzon6191:
