Infecté par Win32:agent kir

Bonjour, je tourne sur XP

je suis infecté par plusieur virus, ( détéctés par Avast):

C:\windows\system32\drivers\lp6fw.syswin32:agent kir (trj)
C:\windows\driver\runtime.sys win32: agent.meb
C:document~1\nicola~\local~1\497015.exe win32:small-epj

les virus m'ont suprimé mon panneau de config, fait disparaitre internet explorer, msn, et viré win32.exe .
je n'arrive pas a instaler kaspersky , je recois ce message "l'administrateur system a configuré la politique de votre systeme pour interdire cette instalation" bien que je soit connecté comme administrateur ?

j'ai fait un scan avec hitjack :
