        Compile and upload to the victim's desktop as one of the following hidden DLL files:
        - sqmapi.dll
        - imageres.dll
        - schannel.dll

        Run IE7 and watch the nice calculators pop up.
        Filter fdwReason to execute only once.

        Tested on WinXP SP2 with fully patched IE7.
        For testing/educational purpose only!
