Ciao sarah03 .
Il log non presenta infezioni.
Però, 2 antivirus sono troppi, e pericolosi.
Disistallane 1.
Scarica questo Tooll, e scegli quale disistallare: (eseguilo come Amministratore)
Scarica AppRemover:
http://www.appremover.com/
Salvalo sul desktop.
Eseguilo.
Nella prima schermata clicca "Next"
Alla seconda, basta selezionare il programma da eliminare e clicca su "Next".
Un'altro click su "Next", e il programma da te scelto dovrebbe essere eliminato completamente.
Fai una pulizia con CCleaner.
Riavvia il pc.

Perchè "litigano" fra di loro.
In parole povere, entrano in conflitto, fra di loro, con il risultato, che nel frattempo i virus entrano senza essere fermati.
In pratica, per i loro "litigi," il pc, è come se non avesse nessuna protezione.
Regola numero 1:
MAI 2 antivirus sullo stesso pc.
