Come eliminare pagine pubblicitarie che si aprono navigando

[reximm]

E' da un po di tempo che mi si riaprono nuovamente delle pagine pubblicitarie indesiderate mentre navigo. Le pagine che si aprono sono del tutto attinenti con le pagine che visito, pertanto, se sono su pagine sportive mi si aprono improvvisamente pagine di siti di scommesse; se visito pagine di banche, mi si aprono pagine di banche dove effettuare aperture di conto ecc.
Dicevo prima, mi si riaprono, perchè tempo fa ho avuto lo stesso problema che prontamento ho risolto per un bel pezzo di tempo ma adesso è ricomparso il problema e ho perso la procedura per eliminare il difetto. Qualcuno può aiutarmi?
Grazie.

Ciao,
Scarica Hijackthis , scompattalo in una cartella a lui dedicata (tipo C:/Programmi/Hijackthis), avvialo e premi Do a Sistem scan and Save a Log file. Copia e incolla sul forum il log che ti verrà fuori.

il log era lungo e non si inviava in unico commento, pertanto è diviso fra i due post. Cosa faccio adesso?

Controlla in installazione applicazioni se è presente il programma Offerbox, se presente disinstallalo.

Scarica e installa Malwarebytes . Aggiornalo e fai una scansione completa del computer. Posta il rapporto ottenuto. Per ora non rimuovere nessuna eventuale minaccia rilevata, aspetta nostre conferme.

[reximm]

Ho fatto tutto come spiegato, Mi sa tanto che il problema è stato risolto perchè da 10 minuti che mi sono ricollegato dopo avere fatto la procedura e nessuna pagina indeswiderata è comparsa.
Per quanto riguarda l'antimalware, invece ho provveduto come spiegato ma il programma ha rivelato ben 265 minaccie che ha provveduto lui stesso a mettere in quarantena e adesso non riesco più e prendere questi fila per postarli, cosa faccio?
