Ciao a tutti.
Da circa 10 giorni ho notato una lentezza incredibile del mio pc, non solo durante la navigazione....
A volta quando scrivo una email sulla pagina di libero, alcune lettere delle parole saltano....come se in quell'istante il pc fosse instabile per cui non riceve l'input in riferimento a quella lettera digitata.
Ho già usato malwarebites, adwcleaner, avast, windows defender.
Potreste darmi una occhiata anche al log di Hijackthis?
Grazie infinite a tutti.

ciao lukeluke allega i log delle scansioni fatte, caricale qui

Ciao cari amici.
Purtroppo non ho più i log, ma li guardai con attenzione e notai che non era stato trovato nulla né eliminato nulla.
L'unico log che purtroppo non riesco ad interpretare è quello di Hijackthis. Vedete qualcosa di anomalo? Un caro saluto a voi.

Scusate l'OT.Bentornato shapiro.

Salve
Bentornato Gringo
Saluti
