About this interactive

What you are doing: placing each case of problem software into its kind. The four kinds: cryptojacking secretly uses the victim’s processor and power to mine cryptocurrency, so someone else collects the reward. Adware shows advertisements the installer is paid for, and can smuggle in other malware. Scareware uses a fake alarm — a bogus virus warning — to frighten the user into installing malicious software themselves. Bloatware is unnecessary software, often pre-installed, that fills storage and slows the machine without being deceptive. How to use it: ask what it is after. Mining coins is cryptojacking. Paid ads is adware. A scary fake warning is scareware. Dead weight that just slows things is bloatware.
