BonziKill serves as a stark reminder of the "Wild West" era of the internet, where spyware was often overlooked in favor of free, flashy software. While the original BonziBUDDY was officially discontinued in 2004, its transformation into BonziKill highlights the rise of "meme malware"—programs that are not designed for financial gain (like ransomware) but for the chaos and disruption of a user's digital life.

Thank you for this great article, I learned about useful functions that where new to me!

How would you go about to handle downloaded files with dynamic file names. I need to get the last downloaded file (a solution to get the only file in the download fodler is also applicable). I didn’t find a solution to get the name of the file while downloading, to change the filename or to intercept the traffic (the file is downloaded without any requests that can be intercepted).
Thank you!
