Sono 10 giorni che non riesco più ad avere il computer efficiente...si blocca nelle applicazioni e nella navigazione....ho scansionato molte volte in modalità provvisoria con malwarebytes...advcleaner...jrt...spybot...drweb...ed oggi anche con norman...sistemato più volte con advanced system care...ma niente migliora momentaneamente ma poi si ripresentano le stesse anomalie...chiedo davvero una mano. Grazie

Hai un'infezione da spigot che è da rimuovere, le scansione fatte avrebbero dovuto trovarlo, l'errore è di averle fatte in provvisoria, andavano fatte in mod. normale, alcune non servono a niente, tipo: spybot, drweb e norton ed anche advanced system care.

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:

Controlla fra i componenti aggiuntivi dei browser che usi se ci sono "Bling Toolbar" e "Slick Savings" se ci sono le selezioni e poi cliccare su "Rimuovi".

Controlla anche fra i motori di ricerca ed elimina search.yahoo.com.

Poi ripeti queste scansioni:

Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.aiutamici.com/software?id=80346
Clicca su: Link al sito principale, poi nella pagina che appare clicca su: Free Version Download.
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione COMPLETA del sistema. (NON veloce)
Elimina gli eventuali file infetti trovati. (li devi selezionare, e poi cliccare su "Rimuovi selezionati")
Posta il log.

Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/2-adwcleaner
Chiudi tutti i browser (è importante IE,Firefox Chrome ecc...)
Clicca sul pulsante "Scan".
Finita la scansione clicca su "Clean"
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui.

Scarica JunkerRemovalTool da qui: http://thisisudax.org/downloads/JRT.exe
Una volta scaricato chiudere tutti i programmi e il browser, per evitare conflitti disattiva momentaneamente anche l’antivirus, lancialo cliccando sull’eseguibile.
Per Vista win 7 e win 8 clic col destro sull’eseguibile ed Eseguire come Amministratore.
Appare il prompt dei comandi, premere un tasto per continuare e il programma inizia la scansione, può durare diversi minuti, lascia fare senza toccare nulla anche se sembra fermo, alla fine appare il Blocco Note col log, JRT.txt copialo e postalo qui.

Tutte le scansioni vanno fatte in modalità NORMALE.


Poi fai una pulizia con Ccleaner compreso il Registro, per il Registro spunta tutte le voci, acconsenti al backup quando richiesto, sempre in Ccleaner vai in Strumenti Ripristino Sistema seleziona tutte le voci tranne l'ultima che non è selezionabile e rimane per sicurezza, poi clic su Rimuovi.
Se non conosci il programma, lo trovi su Aiutamici sezione software.

Vai in C:\windows, cerca la cartella Prefetch aprila ed elimina tutto il contenuto, non eliminare la cartella.

Fai sapere se il pc è migliorato. Ciao
