Update on ur_waifu.
11:43pm. My progress on ur_waifu has been positive for the last few days. For those who do not know, ur_waifu is a computer worm for Windows, which I decided to write for educational purposes only. Windows Defender can easily identify scripts that execute other scripts. Moreover, Defender prevents programs from easily accessing the system32 folder. I think that folder is the meat of Windows and if I cannot get into it, all my hard work will go in vain. So, my first priorities is to find some way to get write access in Program Files and system32 folders.
But, anyway, the worm is complete. Although still quite inefficient at 1.322 seconds for 255 copies on my machine, I am trying to make the program multi-threaded. I think this should work for now, however, I had plans to execute the copies of the worm and let Windows shell (command prompt/PowerShell) handle the executions -- but it seems I'll have to look after it now.
