Ciao, non hai detto quale virus hai trovato, nel log l'unica voce sospetta riguarda CrossriderApp, poi conosci questo sw: Certo LTD\claro\1.6.4.1 lo hai installato tu ? questo programma ha una toolbar che è un dirottatore
nel log non la vedo, magari l'hai eliminata, comunque io lo toglierei.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked:

Fai una pulizia con Ccleaner QUI compreso il Registro.
Installa Malwarebytes QUI lo devi aggiornare e poi fai una scansione COMPLETA non veloce, elimina quello che trova, posta il suo log.
Fai sapere se hai problemi, ciao.
