J'ai plusieurs trojans

Bonjour,
voila je voudrai vous dire que j'ai attraper des trojans ou virus (mon antivirus antivir l'avait signaler mais on dirrait qu'il n'a pas tout bloquer)

Les symptomes sont que : au bout d'un certain temps l'ordinateur devient tres long et parfois se bloque completement et souvent je n'ai plus accés au net alors que ma connexion fonctionne !
J'ai aussi plusieurs alertes de antivir comme quoi un trojan essaie de s'infiltrer meme quand j'utilise pas le pc.
Maintenant quand je viens de demarrer mon pc, mon fond d'ecran a changer : y a une page blanche avec ecrit dessus (en forme d'alerte) :
