The Benefits Of Having A Computer Network In Your Office

techno10

So, we have all heard about computer networking, and we are familiar with such terms such as LAN (Local Area Netowork), Ethernet, and others. But what exactly is a network, and how can it be beneficial to have one implemented in your business? Let’s take a quick peek and see if we can find a few answers.

In essence, a network is a way of interconnecting a group of computers that are usually close to one another. The main purpose of creating a network is to simplify and allow the flow of information and resources among different computers and their users. The first known computer network was created to benefit the United States Department of Defend in the late 1960’s so that information could be exchanged in an easier, quicker, and perhaps more secretive manner.

There are three main methods in which computers are connected today: through Ethernet, which is a physical cable that attaches to each computer, which involves the use of bridges, routers, hubs, and switches; fiber-optics, which allow for greater distances between computers, with quicker communication between them; and one of the most popular, the Wireless LAN connection, which involves only a small router and no wires at all, as the name suggests.

One great benefit that many offices frequently take use is office e-mail. Instead of making phone calls, scheduling a meeting, or trying to make an announcement, supervisors may quickly jot down a memo and disperse it to whomever they need to see it–the whole office, or an exclusive group of employees. This also allows for the secure transmission of confidential information, such as financial records, which in turn cuts down on unnecessary paperwork.

Having a network in the office also allows for several conveniences. One such is a document repository. This creates a space for public folders, which can be accessed through the exchange server.

Public folders may contain items that all employees may need to access, like the employee handbook or vacation schedules. This can make it easier to bring on new employees, as they will have many helpful hints right at their fingertips so that they will not have to run to a supervisor every time they forget what to do–they can simply look it up!

Electronic time clocks are also very useful to employers. Clocking in and out is often done through a secret pin number and an electronic fingerprint reader. While we would all love for our employees to be wholly honest citizens who would never have someone clock in or out for them, this is an added measure to prevent such behaviors.

All in all, an office computer network provides many benefits and conveniences to its users as it helps in streamlining communication among all workers.

How Trojan Horse Viruses Can Attack Your Computer

techno3

A trojan Horse virus is so called because of its reference to the Greek legend of Troy. The legend goes that a large wooden horse was left outside the gates of Troy as a peace offering from the Greeks, whom the trojans were at war with. Once inside, the horse burst open to reveal Greek soldiers who then destroyed the city.

trojan Horse viruses are similar because they appear to be a harmless program but once installed on your computer can wreak havoc with a number of viruses potentially hidden in its code. There is a slight difference between a Trojan Horse and an actual computer virus however. Unlike typical computer viruses, a Trojan Horse does not replicate itself.

One type of Trojan is known as Spyware. This type of program is designed to monitor your Internet surfing habits and use that information for things such as targeted marketing.

Another common problem that Trojan cause is the installation of a backdoor. This means that hackers have a hidden entrance to your computer in which they can send you spam, take control of your computer, or even destroy it. These types of Trojans can be very hard to detect and eradicate.

How Trojans are Distributed

You may be wondering how to protect yourself against Trojans. The first line of defense is knowing how they are distributed.

One of the most common ways is via a useful program such as a computer utility. Once you run the program with the hidden Trojan it can do what it wishes with your computer. Another common way to get a Trojan is through an email attachment. Many people receive executable files through email and don’t think twice about running it on their computer. Once the program is run, you have a Trojan. If you ever get an attachment with an .exe at the end make sure you run a virus scan before opening it.

It is even possible to embed an image with a Trojan. Once you view the picture the Trojan has invaded your computer. It is best to never open files, regardless of type, if you don’t know where they came from. Even well-meaning friends can accidentally email you an attachment which contains a Trojan.

Trojans often take advantage of your computer’s operating system and ports which connect it to the Internet. Some Trojans even allow others to take remote control over your computer and steal keystrokes which may just be your credit card number.

Fighting Trojans

Other than being wary of what you open and install, the best defense is an up to date anti-virus program. It is important that you ensure your anti-virus software is always current since new viruses come out each day. You can typically download free updates from the software provider. You should also ensure you have a firewall to protect you while online.

How To Fully Clean A Virus Off Your Computer

techno11

If you are anything like I am, you have been infected by at least one virus and occasionally have a really hard time removing it. I will show you to remove these tough viruses without having to rebuild your computer or pay someone big money to do so.

Ok so you notice your computer is running very slow. You run your virus scan software and find one or more viruses. You clean them up and your computer still runs slow. You cant figure out why so you run another scan and find out that the same virus is still on your computer. How does this happen?

Basically, there are viruses that will drop into protected system files or startup files that hide within your computer. Sometimes they cannot be removed without rebuilding your computer but there are a few ways around this.

First things first, get a computer toolkit ready to destroy the virus on multiple levels. I recommend a spybot scanner, adware scanner, and virus scan. Plus it always helps to have a strong registry cleaner. Once you have all of these tools ready to go, get them updated fully and download the latest versions of each if possible. After you have updated all of these tools DISCONNECT your internet connection from the computer.

It is essential to disconnect from the internet because most of the imbedded viruses will connect to their host site after the main piece is removed and will download and install itself again without you knowing. Run all of your scan utilities first and restart your computer after they have finished. Once the computer is started up, run the scans once more and restart if the virus is back. If you cannot remove the virus within three restarts, further action is required and will more than likely result in a rebuild.

If you remove it, run a registry clean to remove any leftover tag files. This will also help speed up your computer slightly. Refer to my article 5 Easy Tips To Keep Your Computer Running Smooth And Safe for more computer optimization tips. Restart once more and connect to the internet once more. You should run one more scan to verify the virus is gone. If it is we are ready to go. If it isnt removed you will have to take a couple more steps.
Use your scan utilities to find out exactly where the files are located and remove them from the registry. Be warned that removing registry files can break your operating system.
