Virus win 32 scarmorph et win 32 rootkit-gen

Bonjour,

j'ai installé avast (version familale) depuis plus d'un an , mais depuis qques semaines il m'indique la presence de ad ware + virus ( win 32: scarmorph et win 32 rootkit-gen) qu'il a laisser entrer sur le PC et, ne les élimine pas.
en consultant le forum, j'ai télécharger le hijackThis. Evidemment, j'y comprends rien. je jais un copier coller pour lecture auprès de personnes compétantes.
si quelqu'un peut m'indiquer la marche à suivre pour me débarrasser de ces intrus, je vous écoute...
d'avance merci
