Da qualche giorno ho un problema quando visito un sito (un dizionario online) che uso in realtà da anni, affidabile, non mi hai mai dato problemi. Quasi sempre mi si apre la schermata che mi annuncia che Adobe Flash Player deve essere aggiornato; chiaramente non ho mai accettato, né scaricato alcunché. Inoltre, talvolta mi capita di essere reindirizzata su altri siti o pagine, che chiaramente chiudo all'istante. Tutto ciò mi capita solo con quel sito; navigando in rete, a parte le fastidiose finestre pubblicitarie laterali (che non so se costituiscono effettivamente un problema), non ho problemi. Pur non avendo scaricato nulla, ho eseguito una scansione con Malwarebytes-free (e non solo
), che non ha trovato nulla. I problemi però persistono e non so come risolvere. Qualcuno può darmi una mano e indicarmi come eliminare il problema? Riposto inoltre il report di EtreCheck. Non essendo (come si capisce bene
) un genio dell'informatica e ipocondriaca rispetto alla saluta del mio pc , vorrei fare una controllatina con il vostro aiuto
