Da alcuni giorni mentre sfoglio le pagine web ogni qualvolta apro una nuova pagina mi appare una finestra pubblicitaria a tutto schermo senza che io abbia cliccato per accedere a tale pagina.
La cosa, abbastanza fastidiosa, non riesco ad eliminarla. nonostante abbia antivirus aggiornato (AVAST) + antispyware (Spyware terminator). Cosa posso fare?
Se ho postato questo topic in una sezione sbagliata vi prego volermi indirizzare la sezione giusta. Grazie della Vostra attenzione.

Ciao il topic è nella sezione giusta, tranquillo.
Senti le pagine che ti si aprono c'è per caso scritto un CID davanti?
Se è quello è un fastidioso inquilino che comunque con l'aiuto degli amici ho eliminato.

Abbi fiducia che presto qcl dei nostri amici più bravi di me ti aiuterà.

ho fatto come mia hai indicato, ma non ho risolto nienete ogni tanto mi appare una finestra di pubblicità a tutto schermo. Ho fatto il log che ti allego:
