    Windows Vista Windows defender stops clibration loader from starting

    A recent update to Windows Defender (KB915597 Def.1.33.9770.6) is preventing my Calibration Loader from starting up when I start windows. As a result I have to restore to previous restore point every time I start my computer. Any ideas? Yakir
