Users should know about the basic nature of viruses

When it comes to cybersecurity, many users don't know about the basic nature of viruses.

In a series of lectures in the 1940s, mathematician John von Neumann speculated if it would be possible for a "mechanical" organism such as a computer code to damage machines, copy itself and infect new hosts, just like a biological virus.

Over the last 60 years, computer viruses have abounded, yet what was once cyber vandalism has turned into cybercrime.
