SVP problèmes avec quelques virus

Bonsoir,
Je viens de formater mon ordinateur a cause de virus persistants mais d'autre sont apparu tout d'abord "W32.toxbot" qui aprés quelques manipulation a mystérieusement disparu. Et à présent je lutte avec "hacktool rotkit" ayant élu domicile sur le fichier "spoolv.sys"
A force de chercher des réponses j'ai appris que le programme hijack pouvais vous être utile.
S'il vous plait. Quelqu'un pourrait il analyser ce rapport et m'aider .
