Désinstaller mIRC

Bonjour,
je rencontre exactement le même problème que PierrePaul du 26 mai 2006 :
dès que j'allume mon pc plusieurs fenêtres mIRC apparaissent à l'écran, j'ai supprimé les fichiers mais cela revient toujours. J'ai fait HiJackThis et voilà ce que ça donne. Si quelqu'un pouvait m'aider, ce serait sympa :
