Virus csrss.exe

Bonjour à tous,

Etant un mauvais utilisateur de mon ordinateur me voilà avec des programmes plus que bizarre ! alors lorsque je fais ctrl/alt/suppr j'observe certains programmes "suspect" je nettoie régulièrement ma machine avec ccleaner et je viens de faire un scan avec spybot et rien n'a faire ! ces programmes sont toujours présent les voici.
csrss.exe
winlogon.exe
atieclxx.exe

Je vous colle un rapport hijackthis Ps: Je suis très curieux de savoir comment vous faite pour détecter des virus à partir de ce genre de rapport. Vous pouvez m'expliquer ?

Merci d'avance
