Question

Quizplus · Accepted Answer

A stealth virus is designed to hide itself from detection by antivirus software and can be challenging to detect because it actively tries to avoid detection. Polymorphic viruses change their code structure with every infection to evade detection, but they do not actively avoid detection like a stealth virus. Companion viruses create a new file with the same name as an existing legitimate file to trick users into executing the virus instead of the legitimate file. Heuristic viruses use advanced pattern recognition and analysis to detect and isolate new and unknown viruses, which is the opposite of what a stealth virus aims to do.
