    Your videos have always been calming to me. Hearing just the computer running at the end was nice and relaxing and brought back pleasant memories of me as a child sleeping with an old computer at my desk quietly whirring through the night. Your voice is very nice and soft, too. It's like computer-based ASMR. Which is perfect.

    I'm glad you've been exploring some more viruses recently! These ones you've been going over lately that have bugs or errors in them are hilarious. I know you said at one point these were all coincidental; Do you enjoy them more when they have bugs, or do you prefer them to do what they were purposed to do?

    Hey, love you vids! Just one question, do you follow a process to get the virus to work because when I try to run one (usualy the same one in the video I am watching) everything just freezes and nothing happens? This only happens when I try a DOS virus but win9x or win32 and other viruses work fine. Im guessing it is something to do with my DOS installation.

  • Reply soul taker June 25, 2016 at 12:53 pm

    I know a old virus you could cover it was called sp0rkeh it was made by a myg0ts user to "troll" people on cs source.

  • Reply Noxedwin Tepes June 25, 2016 at 1:33 pm

    It always makes me laugh to see a piece of malware not do what it's supposed to because of a programming bug. Surely if you wanted to do damage, you'd test your new malware on a scratch-monkey machine or something to make sure it formats what its supposed to. You had one stab at the technological world, and you whiffed it, you fuckwad.
    Also, thanks YouTube, for screwing up the comments again, because I seem to be unable to line-break shit.

    Is it possible that so many of the viruses have a programming error that limits the payload on purpose so that the 'scene' at the time could easily share them, with instructions on how to fix the deliberate error?
    Anyone who was active with this sort of thing back then care to confrim or deny?
