Sembra tutto in ordine, ho navigato per un pò e nn si sono aperte finestre, ma come mai altri programmi (antivirus ecc.) non rilevavano l'intruso?

postami un nuovo log di hjt

il log non presenta nessuna anomalia ( a parte la toolbar di crawler) l'ho gia' scritto prima puoi toglierla se non ti serve

dovresti pero' rifarmi la scansione completa con malwarebytes....molto probabilmente quella di prima era quella rapida

comunque le finestre si aprono ancora?

vedi attentamente

la scansione devi farla spuntando quella completa

la toolbar lasciala

se trova qualcosa devo eliminare?

ok, ora faccio finire quella in corso, se nn trova niente ne faccio una in provvisoria e posto il log

disattiva il ripristino, riavvia e riattivalo.... dimmi se noti cambiamenti

per disattivare il ripristino

1. Clic su Start
2. Clic con tasto destro su "Risorse del computer" e sceglere "Proprietà"
3. Selezionare "Ripristino configurazione di sistema", quindi mettere il segno di spunta su "Disattiva Ripristino configurazione di sistema" (o "Disattiva Ripristino configurazione di sistema su tutte le unità")
4. Clic su "Applica"
ti apparira' il messaggio che ti dice ''SI E' SCELTO DI DISATTIVARE RIPRISTINO ecc...ecc.. DISATTIVARE RIPRISTINO?
6. Clic su "Si" per confermare.
7. Fare clic su OK.
