il mcafee è ormai scaduto era una versione di prova che era installata nel portatile già al momento dell'acquisto ma ora non riesco a disinstallarlo completamente, poi il pc mi indirizza spesso su pagine indesiderata,con la scansione di malware bytes le cose vanno già un pò meglio,mi da i soliti problemi ma meno di frequente,anche se il problema non è stato risolto del tutto purtroppo,grazie cmq per i consigli che mi avete dato fin ora
