Suis-je infecté?

Voila tout les jours quand je fais un scan avec Spybot il me donne toujours les memes spywares à eliminer.
Pourtant si j'en fai 2 à la suite rien, le 2eme il me dit que c'est nickel.

Voici un rapport mais si il n'y a rien de suspect, comment bloquer ces spywares avant qu'ils n'arrivent sur le PC. merci d'avance.
