Buongiorno a tutti!
Qualcuno può gentilmente controllarmi il log?
Il pc è un po' lento...
Grazie

Nessuna infezione apparente, hai questo file che è per l'aggiornamento a win 10: C:\Windows\system32\GWX\GWX.exe

Li puoi disattivare facilmente con ccleaner>Strumenti>Avvio doppio clic su ogni voce e si disattiva.
Si sa che la lentezza del pc può dipendere da molti fattori, comunque le solite pulizie fanno sempre bene:
Malwarebytes - AdwCleaner -JRT programmi che credo tu già conosca.
Ciao

JRT ha tolto dei file Temp per il resto è tutto a posto.
In certi orari è facile incappare in rallentamenti, molto traffico e server intasati, se il secondo pc è collegato in wifi il rallentamento è maggiore.
Win 10 io ancora non l'ho installato, ci sono ancora parecchi problemi da risolvere, meglio attendere almeno fino a giugno, win 8.1 mi va benissimo. Ciao
