Trojaner-Board - Trojaner W32MyzorFK@yf - wie kann ich ihn entfernen ?

Hallo, ich habe auf meinem WinXP einen Trojaner. In der rechten Desktop-Leiste erscheint ein gelbes Warnungszeichen, dass mir sagt mein PC sei infiziert. Im Internetexplorer werde ich immer auf verschiedene Anti-Spy-Ware seiten geleitet. Mein Virenprogram E-trust findet jedoch nichts.
Anbei sende ich mein Logfile. Kann mir bitte jemand sagen wie ich nun weiter vorgehen muss ?
Ich kenne mich leider nicht besonders gut aus...
Vielen Dank und Gruss, Sue
