Speaking of viruses, I recently came across a computer virus known as MEMZ (by watching someone else download it to see what it did, fortunately). Disguised as either an .EXE or .BAT file, it basically slowly takes control of your computer’s functions (inverts colors, makes mouse move on its own, searches stuff on google, etc.) until it’s basically unusable. Rebooting doesn’t help either, since the virus messes with the boot settings. This virus doesn’t just destroy your computer, it laughs in your face while doing so. Oh, and it also has memes as payloads, as you probably guessed from the name.
While I don’t think that most people would try running such a thing on their computer without taking precautions (unless you’re overly curious and have never heard of it), I could imagine an unscrupulous person renaming it and tricking an unsuspecting (and possibly gullible) adversary into running it. While I don’t think the creator meant it to be taken as a serious threat, it always poses a danger to people who are just a little bit careless when downloading stuff from the web.
