Is your computer slowing down? You are not alone. A lot of people complain that the older their computer gets the slower they get. While it is true that age affects the speed of a computer, if you can regularly clean it, you will have it running at good speeds for a very long time.

What does keeping your computer clean mean? It means that you don’t let your computer get exposed to any dangerous software. There are 3 ways to do this.

1. Keep away from viruses and malware

These are usually picked up from the internet; sharing devices can also give your computer a virus. There are some sites that are more likely to give you a virus than others. Porn and bit torrent sites are notorious. So are the websites that flash an ad asking you to download free screensavers and wall papers. If you want a screensaver or wall paper, look for a legitimate site.

It is not advisable to share devices like flash disks. You may plug one into your computer that contains a virus. If you absolutely must, run it through an antivirus first.

2. Keep your computer protected

A virus or other malicious software may somehow get into your computer and begin to replicate. This can only be stopped using antivirus software and a firewall. The antivirus goes after the bad code while a firewall keeps it from spreading throughout the computer.

There are different kinds of antivirus software. Some are for computers that are used for routine tasks – Microsoft programs and a little surfing. A machine that is used for a lot of internet interaction is continually exposed and may need a more complex antivirus.

You should also consider the level of security that you need; if it is high, then you need a powerful antivirus.

There are free antivirus programs on the internet that provide basic security but if you want high level security, install one that is paid for. You should also make sure that you program the software to update automatically. New viruses are released all the time and you don’t want to take a chance.

3. Make unauthorized access difficult

If anyone ca use your computer, they can go to whatever sites they want and they may pick up viruses. You should always password protect your machine especially if you use it in an office setting. Make sure that your password is not obvious and contains both numbers and letters to make it hard to crack. You should change it every few months.

Virtual Private Network vs. Proxy

VPN technology enables internet users within an organization connect to their network and work virtually from any location. These people can be employees in different geographic locations. Others can be in remote areas such as offshore oil rigs or mining areas far from civilization. The connection is very secure and efficient meaning work flow is not interrupted. An outsider cannot read any intercepted data since it is already encrypted.

On the other hand, a proxy refers an application or system whose function is acting as a go between for users searching for resources from other applications. In IT jargon, such an application is known as a server. So, whenever you need a service, you are connected to such a server from another one. The proxy server appraises your request and simplifies it for you. In the end, you get what you are looking for. These activities are electronically controlled and happen very fast such that you will not be able to notice.

The proxies in use today are known as web proxies. Their work is to facilitate access to internet content. Here are the potential uses of proxy servers.

– They help keep machines in a network secure.
– They hasten the process of accessing resources.
– Prevent a multiple download of similar content thus saving bandwidth.
– They provide a log on how employees use the internet.
– They scan all incoming and outgoing content for risks such as malware or data loss

For comparison purposes, here is what a VPN does:

– Connects users to the business network.
– Allows you to work from home or another location.
– Users exchange data and other useful information in real time.


1. Proxy servers and VPNs

They act as connectors allowing you to get through to other resources within a network. The server need not located in your locality, it could be anywhere. Proxies are responsible for the requests you make to connect to a webpage or files. From where you sit, you are oblivious of the operations taking place behind the scenes. Since the connections may not be always secure, you need a VPN to encrypt the information going back and forth

2. Security

A proxy server is merely a conduit and can allow any kind of data to pass through. Going by the fact that the internet is a public place, you need to ensure that there are no unwanted elements within your intranet. Third parties can gain access to your data with dire consequences on your part. To clean and keep them out, VPN connections secure the transmission of data. In addition, VPNs facilitate this transmission either within a small or large geographical area.

3. Privacy and confidentiality

An anonymous proxy server is well able to secure any computers behind it as well as maintain privacy. Free proxies on the other hand are slow in connectivity. This hinders timely transfer of data and can lead to spamming. To cut the slack and increase efficiency, a VPN network is required. This helps make you networks reliable and maintain data confidentiality.

DNS services are a good alternative to VPNs and Web proxies. They work in a slightly different way… They require a bit of setup work, but once they are set up, they permanently hide your real IP address, which means that you can access geo-restricted content at any time, without having to launch a VPN program or a Web proxy. The most popular DNS service is Unlocator.
