Plus aucun programme ne s'ouvre!

salut à tous,

Voila mon probleme : Alors que mon PC tourne tranquillement sans probleme, il arrive un moment où soudainement plus aucun fichiers executables ne fonctionne : le sablier est actif pendant qq sec mais rien ne se passe.J 'ai beau double cliquer sur les programmes du bureau ou passer par menu démmarer, rien n'y fait.
je ne peux meme pas redemmarer, je suis obliger de faire RESET.
Serait-ce un virus, un trojan ........

Ci joint un rapport hijakthis .
