Security is essential for survival in the world we live in. If that is contestable, then imagine living in the jungle and living your doors wide open, night or day. Frightening right when you think of good neighbours like a nearby lion pride? So also it is when making use of a personal computer. As you work online or offline you are at a risk of your system being infected by Viruses or Malware.
What Viruses are
“Viruses are computer programs or scripts that attempt to spread from one file to another on a single computer or from one computer to another, using a variety of methods, without the knowledge and consent of the computer user.”[i] For Microsoft, “what makes a virus a virus is that it spreads itself. The damage it does is often incidental when making a diagnosis.”[ii] In other words, viruses can be said to cause harm unintentionally because the authors did not anticipate the full effect or unintentional side effects of such programmes.
An example of a harmful virus is the Trojan. It attempts to infiltrate a computer without the user’s knowledge or consent. Trojans usually spread through instant-messaging software, e-mail attachments, or Web downloads. Some activities of Trojans include “browsing the hard drive to steal data, logging key strokes to acquire personal passwords or account numbers, erasing files, shutting down the computer at random, sending spam from the user's e-mail account, or deleting the entire hard drive.
Two Security Tools you should have
As you make use of your computer, below are two tools you should not do without in no particular order of preference. Of course there are other great tools out there:
1. Microsoft Security Essentials
This is currently what I use on my Acer Extensa running Windows 7 Ultimate OS. Use Microsoft Security Essentials to guard against viruses, spyware, and other malware. It provides real-time protection for your home or small business PCs whether you are online or offline.
Microsoft Security Essentials is free and and is designed to be simple to install and easy to use. It runs quietly and efficiently in the background so you don't have to worry about interruptions or making updates, though you may want to update it from time to time as new virus definitions are released by Microsoft.
Microsoft Security Essentials is also available for small businesses with up to 10 PCs. If your business has more than 10 PCs, you can protect them with Microsoft Forefront Endpoint Protection. Please note that, to use Microsoft Security Essentials you must be running a genuine windows os. To download it now, Click Here
