Ralentissements, blocage

tu a fais une analyse antivirus.

oui, il n'y avait que HEUR/HTML.Malware
Tout est Ok, à priori, une alerte aussi je crois.

quand tu fais ctrl+alt+suppr ta memoire et ton uc son surcharger ou pas dis moi les pourcentage stp

Firefox emploi 196 000 K,
ça bouge en permanence pour les pourcentage UC de l'ordre de 17, 44, 58, 60, , 62%....

tu peux me donner les caractéristique détaillé de ton ordinateur stp
et démarre en mode sans échec puis refait un scanner mais online par exemple avec kaspersky
https://www.kaspersky.fr/?domain=webscanner.kaspersky.fr

PS:quand a tu eu se genre de problème après l'installation d'un logiciel ou c'est venu comme ca

Je ne sais pas, car j'en ai installé plusieurs déjà. Par contre Kaspersky online j'ai déjà tenté mais ça marche pas avec Vista.
Il n'y a pas d'autres alternatives outre BitDefender egalement.
