Protecting your computer from a virus is getting harder and harder each day. While it may border on the paranoid, it goes without saying that you can’t leave your guard down for one second. Even corporate giant Microsoft has found its own systems compromised on more than one occasion.
Remember the “good old days”, before the advent of the Internet and downloadable programs? Life was simple then in terms of computer viruses. With the primary way in which a virus could be transmitted being limited to floppy disks, the ability to catch and eradicate the virus was a lot easier. By today’s standards, it used to take quite a while before a virus was able to infect a computer and slow down the system. The antivirus software of that time was typically able to identify and eradicate viruses before they caused too much damage. Additionally, computer users were pretty savvy on how to protect themselves in terms of scanning all floppy disks before copying them to our desktop.
The Internet helped change all that. The Internet provided a conduit by which viruses could move from host to host with lightening speed. No longer could a computer user just worry about floppy disks as points of entry, but they now had to worry about email, email attachments, peer-to-peer file sharing, instant messaging, and software downloads. Today’s viruses can attack through multiple entry points, spread without human intervention, and take full advantage of vulnerabilities within a system or program. With technology advancing everyday, and the convergence of computers with other mobile devices, the potential of new types of threats also increase.
Protecting Your Computer
Luckily, the advancement of antivirus software has kept pace with current virus threats. Antivirus software is essential to a computer’s ability to fend off viruses and other malicious programs. These products are designed to protect against the ability of a virus to enter a computer through email, web browsers, file servers and desktops. Additionally, these programs offer a centralized control feature that handle deployment, configuration and updating.
A computer user should remain diligent and follow a few simple steps to protect against the threat of a virus:
1. Evaluate your current computer security system.
With the threat of a new generation of viruses able to attack in a multitude of ways, the approach of having just one antivirus software version has become outdated. You need to be confident that you have protected all aspects of your computer system from the desktop to the network, and from the gateway to the server. Consider a more comprehensive security system which includes several features including antivirus, firewall, content filtering, and intrusion detection. This type of system will make it more difficult for the virus to penetrate your system.
2. Only install antivirus software created by a well-known, reputable company.
Because new viruses erupt daily, it is important that you regularly update your antivirus software. Become familiar with the software’s real-time scan feature and configure it to start automatically each time you boot your computer. This will protect your system by automatically checking your computer each time it is powered up.
3. Make it a habit to always scan all new programs or files no matter from where they originate.
4. Exercise caution when opening binary, Word, or Excel documents of unknown sources especially if they were received during an online chat or as an attachment to an email.
5. Perform regular backups in case your system is corrupted. It may be the only way to recover your data if infected.
Recommended Antivirus Software
There are numerous applications available to consumers. With a little research, you can pick the program that is right for you. Many programs provide a trial version which allows you to download the program and test its abilities. However, be aware that some anti-virus programs can be difficult to uninstall. As a precaution make sure to set up a System Restore point before installing.
Here are a few programs which typically receive high marks in terms of cost, effectiveness, ease of use, and customer service.
The Shield Pro 2005™ provides virus protection and hacker security through ongoing support and updates. When a virus breaks out, The Shield Pro 2005™ promises to provide a patch within 2-3 hours and a fix for the virus within 5 hours.

AVG Anti-Virus Free Edition is a free downloadable antivirus program that has received high marks for its reliability. In the past, free downloadable antivirus programs have been viewed skeptically because of issues relating to its reliability. However, AVG from Grisoft, remains one of the best-known free anti-virus programs available. While AVG can not be installed on a server operating system and there is no technical support, it still makes a good choice for many home computer users. The best part is that since it is free, you can try it with no further obligation necessary.

Just what is Intelligent Explorer? For your safety, you really need to know
I recently hit, by mistake, what I thought was an Explorer upgrade option. It turned out to be a pop-up appearing legitimate but really was not. It uploaded a product called Intelligent Explorer on my machine. What a nightmare!
I did some research on the web and found messages like this one from a BullGuard Antivirus Forum,
"PLEASE HELP!!! I HAVE A SPYWARE, TROJAN AND HIJACKER ON MY COMPUTER. I HAVE RUN BULLGUARD, CWSHREDDER AND AD-AWARE. ALL HAVE PICKED UP THE VIRUSES AND SAID THAT THEY HAVE BEEN MOVED/REMOVED BUT WHEN I LOG ONTO THE INTERNET THAT DAMN INTELLIGENT EXPLORER TOOLBAR IS SHOWING"
Another message from spywareinfo Forum goes something like this:
"Hey I'm having issues with something called Internet explorer toolbar - Intelligent explorer. I can’t find a way to remove it from my comp and I really don’t want to reinstall windows. I've used spybot, ad-ware, and cw shredder but nothing seems to work."
It appears that Intelligent Explorer allows other software to be downloaded to your machine and this is where the problem occurs. What is even more remarkable is that by downloading Intelligent Explorer, their license grants them the right to install software add-ins on your computer at their will. Take a look at what the software license for Intelligent Explore says (go to http://www.ieplugin.com/terms.html to read it all):
"You grant to us the right, exercisable by us until you uninstall the Software or this agreement is otherwise terminated, to provide to you the Service of downloading and causing to be displayed advertising material on your computer, through ‘pop-up’ or other display while you use your browser. You acknowledge and agree that installation of the Software may automatically modify toolbars and other settings of your browser. By installing the Software you agree to such modifications."
The company, IBC incorporated, is incorporated in Belize. I really can't believe this license!
One end user found highly objectionable pop-up advertisements generated by this software bundled with Intelligent Explorer in the form of extreme pornography.
I have yet to break this.
Intelligent Explorer is a plug-in, which can create a new home page, as well as start up and endless loop of pop-ups. You can remove the view bar, but then starting up Internet Explorer will cause it to reappear. I asked some friends to help, and no one could tell me what to do.
This is what I did:
I bought a copy of a program called XoftSpy and it removed the software. It took two scans and a reboot to do it. This is not an advertisement for this product. They advertised it was free, which it was to run, but then I had to buy it to actually fix anything. It cost me $40 and I am sure that there are freeware products out there as well, but that is what ended the nightmare for me. Other spyware products I have seen out there include spybot, NoAdware, Spyware Eliminator, Pal Spyware Remover, and Spyware C.O.P.
Let the buyer beware!

About Encryption and Making Your System Secure
What does encryption do for me?
Encryption and cryptographic software has been used in many different ways to make systems more secure. This article discusses only a few ways that such software can make your system more secure, including:
1) Encrypting your email
2) Encrypting your files
To programs are mentioned that will help encrypt information. There are many more programs out there that will help, but these programs are good and a good place to start as any. They have the added benefit of both being free with source code available.
Will encryption stop people from accessing my information?
Encryption simply makes it harder for people to gain access to important information, like passwords or sensitive information in a file. The first thing you should know about encryption is that the algorithm that is used to encrypt can be simple or more complex and that affects how securely what you have encrypted is protected. Encryption systems have been broken when the method of encryption is understood by hackers and is easy to break.
Why bother to encrypt my email?
It should be noted that email is far less secure than paper mail for two very good reasons: first, electronic data can be accessed easily over an Internet and secondly, electronic data is really simple to copy. There is a very good chance that someone has snooped around in your email despite your best intentions to stop it.
How do I go about encrypting my email?
There are many programs out there that can help you encrypt your email. A very popular one is PGP (Pretty Good Privacy) or its Gnu offshoot GPG.
PGP (http://www.pgpi.org/) self-describes itself this way: This "is a program that gives your electronic mail something that it otherwise doesn't have: Privacy. It does this by encrypting your mail so that nobody but the intended person can read it. When encrypted, the message looks like a meaningless jumble of random characters. PGP has proven itself quite capable of resisting even the most sophisticated forms of analysis aimed at reading the encrypted text."
Why bother to encrypt my files?
The answer to this boils down to what you store on your computer. If you have financial data with important information like social security numbers, email addresses, account numbers and passwords, then you open yourself up to losing very valuable information. Most corporate Internet security employees will attest to the widespread theft of very valuable information. As long as you are connected to the Internet you are vulnerable.
How do I go about encrypting my files?
AxCrypt File Encryption Software (http://axcrypt.sourceforge.net/) Self-described as "Free Personal Privacy and Security for Windows 98/ME/NT/2K/XP with AES-128 File Encryption, Compression and transparent Decrypt and Open in the original application."
