Infection swizzor.gen

Bonjour a tous
je suis nouveau sur le forum et en plus étranger, mais de bonne volonté:
soyez patient svp!
Je crois bien que mon ordinateur est infecté par un trojan swizzor.gen.
Depuis ce matin :
- l'historique de Firefox est effacé systématiquement
- l'ordinateur s'eteind tout seul
- la connection va et vient

après scansion avec clamwin voici le report :
