    Installing the version installed a malignant version of Yahoo despite my saying NO to installing it, Worse than pure adware.

    I won't touch any of IObits' software after they ripped off MBAM data.
    Install anything by this company at your peril.

    This good tool runs only at WinNT or hiher, not on 9.x!
