For nearly 50 years, computers have been getting infected with worms and viruses, programs designed to spread from machine to machine. In this video, we take a look at how these digital diseases got their start, alongside more unique examples of self-replicating software.

Many of us at some point in time have had a computer start acting very strange; there are a lot of threats out there, and many come in the form of viruses. Computer viruses got their name because they act like viruses, and replicate. They infect lots of files on a machine and can be spread to another machine by doing thing things like sending files to someone else, or using an infected USB drive on another computer. Then you have worms, adware, Trojans, and Rootkits, which are hard to detect and can give attackers control of your machine. Perhaps even more frightening are ransomware attacks, where someone gets ahold of your data, sometimes sensitive data, and makes you pay to get it back. Today we’ll look at some of the biggest attacks on computers, in this episode of the Infographics Show, The world’s most dangerous computer viruses.

The images of SARS-CoV-2, the novel coronavirus that first appeared in humans in late 2019, were made using electron microscopy. The virus measures around 100 nanometers, and the smallest wavelengths of light that humans can see measure around 400 nanometers, meaning the virus is too small to see with a standard light microscope. To see something that small, you need a device that uses smaller wavelengths than light. Electrons, when accelerated in a field, behave as a wave with a tiny wavelength to accomplish this.
Two electron microscopy techniques, SEM and TEM, offer different views. A Scanning Electron Microscope (SEM) scans the surface of a sample and records information that bounces back, similar to a satellite image. A Transmission Electron Microscope (TEM) transmits electrons through a sample and projects a cross section of its inner structure. Together, these images help scientists observe the virus and how it moves in and out of host cells.

Correction: At 4:07, an animation in a previous version of this video implied that antibodies coat the entire cell membrane, when they actually bind to specific proteins on the virus. The error has been corrected..

We live in a world where viruses and malware are pretty normal. But how do they work? Where do they come from? What’s the difference between viruses and malware? Let’s find out on Waste Time.
How do viruses work? Computer Viruses. The scourge of the digital world. We’ve got Trojans, Worms, Macros, Malware, Spyware; all manner of malevolent programs that can destroy files, erase data, steal passwords or just display a nice little message on a given date. We’ll be looking at DOS Viruses, Windows Viruses, Bootsector viruses, infected executables, all within 6 minutes. This video explores the fundamentals of what a computer virus is, how the different types of virus work and we even see some computer viruses in action, and take a look at a few viruses in the field, including the BRAIN virus. The first IBM PC Compatible virus.

Wales’s health minister has been heard swearing about a colleague during a virtual sitting after he accidentally left his microphone on.
Vaughan Gething had come to the end of answering questions during a plenary session, being held by Zoom, when he made the remarks.
He referred to Jenny Rathbone, Assembly Member for Cardiff Central, and said to an unknown person: “What the —- is the matter with her?”
Elin Jones, presiding officer of the National Assembly for Wales, quickly told Mr Gething to turn his microphone off.
After the session, a spokesman for the Welsh Government said: “The minister has contacted the member concerned to apologise.”
Mr Gething posted on Twitter: “I’m obviously embarrassed about my comments at the end of questions today.
“I’ve sent a message apologising and offered to speak to Jenny Rathbone if she wishes to do so.
“It is an unwelcome distraction at a time of unprecedented challenge.”

Dana Childs: Body, Mind, Spirit, and Soul—Which to Trust?
We tend to think of intuition as a gut feeling, but intuitive healer Dana Childs says we can get tripped up if we trust one of our layers that may not be feeding us the truth. Out of the four layers of the self—physical body, mind, spirit, soul—Childs says that only two provide us with accurate information. How do you know which parts of yourself to trust, and how do you connect to them? In this workshop-meets-Q&A, Childs helps us tune in to the wisdom we all hold within us.
