Visti i molti (file missing) direi che HijackThis non funziona bene con il tuo sistema operativo.

Un programma che 'ragiona' in maniera simile è Hijack Hunter >> http://www.novirusthanks.org/products/hijack-hunter/ e dovrebbe funzionare meglio sui sistemi a 64bit.

Detto questo il log è poco significatico. C'è una certa invadenza di Chrome (opinione personale) e puoi aggiornare Firefox alla versione 36 http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/latest/win32/it/

Se magari puoi spiegare meglio i problemi che riscontri, quale antivirus non riesci a scaricare e che errori visualizzi...

[eagleman]

Oltretutto, se vedo bene, c'è già Avira installato sul computer.

Non si capisce se è il rimasuglio di una vecchia installazione e vuoi installare un antivirus diverso oppure vuoi installare la nuova versione di Avira.

Anche questo è un punto da chiarire.

[robyespoo]

Guardate penso di avere un bel po di rimasugli di vecchi antivirus...

come faccio a levarli?

[eagleman]

Prova con Appremover e vediamo che cosa riesce a scovare.

Non sempre le disinstallazoni ufficiali degli antivirus funzionano fino in fondo. Questo di solito scova anche l'inscovabile.

In seconda battuta, un pulitore di registro può aiutare a dare un'altra sistemata. Io uso la funzione di CCleaner; magari non è perfetta, ma mediamente ha creato pochi problemi al sistema.
