Infection ou non???

Cela fait quelque temps, j'ai toujours une fenêtre net.offer qui s'ouvre n'importe quand, n'importe comment. Je passe mon anti virus et je reçois 20 fichiers vulnérables que je ne peux pas supprimer!!! J'en ai fait une copie ci dessous.
hbtools[1].cab
HbtSrv.exe
HbtToolbar.dll
HbtUninst.exe
HbtWallpaper.dll
jdaivlql.exe
jnmlezay.exe
HbtOEAddOn.exe
HbtInstIE.dll
ShprRprtHbt.exe
HbtHostOL.dll
HbtHostIE.dl
HbtHostOE.dll
Cml.exe
static\1\country.exe
static\2\country.exe

Est-ce que mon PC est infecté et si oui comment m'en défaire? J'ai déjà passé l'anti virus de secuser, adaware et mon anti virus!!!
Merci d'avance

J'ai donc fait la manip avec hijackThis. Voilà le résultat .....
