It starts, as many modern legends do, with a file name. Mike.exe — an innocuous string of characters that, in the dark corners of tech forums and forwarded chat logs, has accreted layers of rumor, fear and folklore until it reads less like software and more like a demon’s true name. “Virus Mike.exe,” the story goes, is a polymorphic specter: sometimes a prankware that bricks old USB sticks, sometimes a ransomware strain demanding a laughably small sum, sometimes an urban-legend-level malware that spreads through curiosity, emboldened clicks, and late-night boldness. Behind every retelling sits a more unsettling truth: in the age of ubiquitous computing, our anxieties about agency, identity and contagion coalesce into the software we fear.
