    Thanks for the great work

    Is it safe to unpack a suspicious file? Or there’s a possibility that packed content can be executed outside the emulation environment?


    niucool Reply:

    Absolutely safe to unpack, the suspicious file is run in my virtual environment, and I emulate what Windows XP OS does, I do not redirect API calls to real system.
    But make sure not to click the “Test” button (it will call real CreateProcess), if your target is a malware.

    Avast says this file is infected with Win32:Dropper-Gen. Beware.

    Ditto, Avast kills d/l, great pity, do not know if it’s a false positive?

    PackerBreaker looks promising for ages i was searching
    for a tool like this hope this one does the job:D
    anyway thank you so very much sir, people like you are a
    god send keep up the great work

    well i can’t use PackerBreaker side by side with a
    debugger like OllyDBG and this makes PackerBreaker kinda useless somewhat i mean, if a debugger is on the memory PackerBreaker won’t run, so every time i use a debugger i must restart my PC, moving on:) i have one problem tho i tested with a custom masm32 program HelloWorld:D and packed with UPX, the test button is disabled is this normal

    one request:LOL if you can do something about PackerBreaker and a debugger running side by side than it
    will be of great help, restarting my PC every now and then is kinda hassle i think you understand the problem

    Thank you

    Sorry for my English its not my native language
