ordinateur est très lent je pense qu'il s'agit d'un virus

Bonjour,

Mon ordinateur est devenu très lent d'un coup.
Voici ma configuration système:

athlon 64 3700+
2 disques durs avec une partition sur le premier et deux sur le deuxième.
Xp installé sur le premier et vista sur une des deux autres partitions.

Que dois-je faire? Adaware, spybot... C'est trop soulant, il est tellement lent que je peux plus rien faire avec !!! un peu d'aide s'il vous plaît. merci pour tout

Voila le rapport:
