virus win32/istbar.er - help me

Bonsoir, j'ai un virus win32/istbar.er dans un fichier que je n'arrive pas à supprimer il se loge dans c:\docum
~1\locals~1\temp\aawtmp\c46859\crack.exe , j'ai essayé de le supprimer avec mon anti-virus ( nod 32 ), des anti-spyware etc... mais à rien faire, il reste là !
Cependant je n'ai pas mozilla comme explorer internet, pouvez vous m'aider, merci.

J'y ai déjà pensé oui, mais quand l'analyse est fini, je ne pouvais pas le supprimer, svp aidez moi, vraiment énervant ce virus

J'ai suivi tes consignes, j'ai nettoyé avec ccleaner puis j'ai redemarré, mais le virus est toujours là, donc voilà le save log du logiciel :
