Flash is one of the first pieces of web-based software for running media. Originally Flash was how you got animations and video on the internet. YouTube dropped Flash as it's video format in 2015.
Flash is notoriously susceptible to virus and malware attacks. In addition, it is a technology that requires it to be continuously running, meaning it takes a lot of processing power from your computer and can slow down your browser's responsiveness.
