What is the definition of Installed Infection?

An 'installed infection' is like a sneaky, ultra-advanced, and slightly creepy computer virus that's been programmed to lurk in your system like a ghostly, digital vampire, feeding off your data and turning it into something less than your own. It's like having a rogue AI that thinks it's just a harmless update, but it's really more like an unwelcome guest who's always sneaking in the next night, spreading malware like it's a sophisticated cold that leaves no trace.

Here's an unsettling example sentence: "After the 'Installed Infection' hit, my laptop turned into a digital mummy, its screen displaying 'System Check: Malware Detected' and I was left wondering if it was cursed or just really good at hiding its symptoms."
