Ransomware is a type of malware that will lock you out of your files, device, or other resources, and demand a payment to regain access. Even if you choose to pay up, most often the payment will not result in gaining back access, and your files are permanently lost.
The threat posed by Ransomware is serious, and ongoing. I last updated this article in September 2015, not long after Cryptolocker became the first widely reported Ransomware threat with thousands of infected computers and resulting in the loss of millions of dollars of data and production. The problem has only increased in frequency and severity with a range of new variants attacking customers across PC and other platforms.
From blinking lights, punch cards and paper tapes, through CRTs, the introduction of colour, and the development of LCD panels; display technology has come a long way.
Today we enjoy a range of inexpensive, high resolution monitors able to display a remarkable amount of information and employing a bewildering range of technologies. This article will identify and explain technological differences between available monitors, and help you weigh your choices to pick the best option for your needs and budget. Read more
AMD have released their most competitive CPU design in 15 years; eight core monsters than can stand toe to toe with Intels best chips — but should you buy one? The answer is maybe.
This article will help you make a purchasing decision based on public data. I will explain where AMDs new design will shine through as well as its limits and how the Ryzen 7 compares with Intel processors.
We see the pattern time and again. “Everyone” agrees that a new technology will transform business and you must be part of it or risk being left behind. Businesses caught up in the hype rush to implement optimistic and poorly thought out projects. Something goes wrong resulting in massive costs and reputational damage. Finally, we take a more cautious and realistic approach to building the new technology into our business models and the technology starts to meet its early promise.
Such is Enterprise mobility. The notebook, smartphone, and broadband wireless are enabling technologies, allowing us to break away from the office and have accelerated a transformation of how we think of the workplace. Benefits from anywhere access to data and tools include a boost to productivity, improved customer service, and flexibility for employees. The concept appears to be a clear win/win with evangelist’s spruiking the undeniable benefits, but often ignoring the security implications. We are a long way down the road to mobile maturity, but we are not quite there yet. Read more
OpenDNS offers a suite of Internet filtering and security features targeted at levels from the home environment to corporates. The service works by replacing the Internet’s standard address book system (DNS) with a custom service which then allows you to limit, track, and manage access to the Internet and to help protect your staff and family from malware, phishing, and inappropriate content.

This article will examine options for backup storage and tools, provide advice on how to choose between them, explain how they can be effectively employed, and give examples of common implementation pitfalls.
Prior articles have worked through the high level conceptual framework and technical concepts that relate to backup systems.
Universal Serial Bus (USB) was developed in the late 90s to replace a mess of slow PC connections with a high speed, one size fits all plug and data transfer protocol. All newish devices had the plug, it was good, and there was no real decision or gotchas to look out for when buying new devices.
A decade or two later, things are again a mess. Incremental changes to USB have offered progressive technical improvements, but at the cost of modified plugs and sometimes questionable backwards compatibility. Read more
The UPS is a misunderstood beast, so we have written this guide to clear up misconceptions and provide information to help you work out if you need one.
At its core, a UPS is a battery that sits between the mains power supply and your equipment. When the power drops out, the battery is there to keep your gear running long enough to save your work and shut it down normally. Read more
This article builds on the high level conceptual framework introduced in our previous backup article.
I will explain technical concepts and related terminology to help you design a Backup System for use in business or home. Read more
Every year, as Christmas approaches, we see an influx of PCs, modems, and other equipment killed by power surges. It is that time of year again, so to head off some of the issues, I thought a timely reminder in order.
When a burst of energy is dumped into the grid, a surge results and the voltage at your power point will jump up above the normal 240V. When the voltage moves above the level that your equipment is designed to handle, damage results. Read more
