I come from a generation of computer nerds that got suspicious when a single character appeared where it didn't belong. "Stop everything we must have a virus". Our little Commodores didn't even have important info in them.

WhatsApp is the most advanced virus spyware malicious code ever made. People install it *willfully* I have lost a lot of connections because I refuse to.
