Buongiorno a tutti,
sono a chiedere un aiuto per il seguente problema che riscontro nell'aprire il pgr Mozilla Firefox.
si apre la pagina javassafety........
ho già eseguito i pgr SuperaAntiSpyware, SpyHunter, Malwarebytes e allego
il log del pgr HiJackThis.
nel riaprire nuovamente Firefox me l'ha riaperta ancora quella maledetta pagina. ho disinstallato Firefox ma nulla da fare.

Ringrazio e saluto.

SpyHunter lo hai pagato?

Penso tu ti riferisca al browser Mozilla Firefox. (non al programma)
Fosse così prova un ripristino firefox:
