Virus?

Bonjour,

J'ai des comportement assez bizarre de mon pc (reboot intempestif, erreur d'install du SP2...)
J'ai donc pensé a une infection de malware, mais après plusieurs scans (spybot et autre) j'ai toujours les même problèmes :(
Je viens de faire analyser le PC (c'est un HP Pavilion) par RSIT. Si quelqu'un voulais bien me dire si je suis infecté ou non, voici le log affiché par RSIT:
