Cybersecurity: a complete guide for businesses and households

People usually start caring about security only once it is too late: after an encrypted computer, a stolen account or a payment sent to a fraudster. Yet 90 % of attacks are not about brilliant hackers, but about ordinary carelessness that a few habits can prevent.
This is a hub page for our security articles. From passwords and antivirus through scams to protecting a business. Pick what you are dealing with, you do not have to read it all at once.
