Problème, virus?

Bonjour,
config: win XP home SP

mon antivirus (mcafee 2008) s'est comme désinstallé. J'ai voulu réinstaller, rien à faire. Impossible tout simplement.
Impossible aussi d'installer spybot, le programme spybotsd.exe est introuvable.
J'ai essayé plusieurs solutions proposées, aucune ne marche, même pas mode sans échec.

Merci à vous de vous intéresser à mon souci. Ci-joint le rapport hijackthis
