Fighting Spam

How prevalent is Spam? According to Scott McAdams, OMA Public Affairs and Communications Department (www.oma.org):

“Studies show unsolicited or “junk” e-mail, known as spam, accounts for roughly half of all e-mail messages received. Although once regarded as little more than a nuisance, the prevalence of spam has increased to the point where many users have begun to express a general lack of confidence in the effectiveness of e-mail transmissions, and increased concern over the spread of computer viruses via unsolicited messages.”

In 2003, President Bush signed the “Can Spam” bill, in December of 2003 which is the first national standards around bulk unsolicited commercial e-mail. The bill, approved by the Senate by a vote of 97 to 0, prohibits senders of unsolicited commercial e-mail from using false return addresses to disguise their identity (spoofing) and the use of dictionaries to generate such mailers.

In addition, it prohibits the use of misleading subject lines and requires that emails include and opt-out mechanism. The legislation also prohibits senders from harvesting addresses off Web sites. Violations constitute a misdemeanor crime subject to up to one year in jail.
One major point that needs to be discussed about this: spam is now coming from other countries in ever-greater numbers. These emails are harder to fight, because they come from outside our country’s laws and regulations. Because the Internet opens borders and thinks globally, these laws are fine and good, but do not stop the problem.

So what do you do about this? Her are the top 5 Rules to do to protect from spam.
Number 1: Do what you can to avoid having your email address out on the net.
There are products called “spam spiders” that search the Internet for email addresses to send email to. If you are interested, do a search on “spam spider” and you will be amazed at what you get back. Interestingly, there is a site, WebPoison.org, which is an open source project geared to fight Internet "spambots" and "spam spiders", by giving them bogus HTML web pages, which contain bogus email addresses.

A couple suggestions for you:
a) use form emails, which can hide addresses or also
b) use addresses like sales@company.com instead of your full address to help battle the problem. c) There are also programs that encode your email, like jsGuard, which encodes your email address on web pages so that while spam spiders find it difficult or impossible to read your email address.

Number 2: Get spam blocking software. There are many programs out there for this. (go to www.cloudmark.com or www.mailwasher.net for example). You may also buy a professional version. Whatever you do, get the software. It will save you time. The software is not foolproof, but they really do help. You usually have to do some manual set up to block certain types of email.

Number 3: Use the multiple email address approach.
There are a lot of free email addresses to be had. If you must subscribe to newsletters, then have a “back-up” email address. It would be like giving your sell phone number to your best friends and the business number to everyone else.

Number 4: Attachments from people you don’t know are BAD, BAD, BAD.
A common problem with spam is that they have attachments and attachments can have viruses. Corporations often have filters that don’t let such things pass to you. Personal email is far more “open country” for spamers. General rule of thumb: if you do not know who is sending you something, DO NOT OPEN THE ATTACHMENT. Secondly, look for services that offer filtering. Firewall vendors offer this type of service as well.

Number 5: Email services now have “bulk-mail” baskets. If what you use currently does not support this, think about moving to a new vender. The concept is simple. If you know someone, they can send you emails. If you don’t know them, put them in the bulk email pile and then “choose” to allow them into your circle. Spam Blocking software has this concept as well, but having extra layers seems critical these days, so it is worth looking into.

Spyware Beware

Spyware and Adware are not only an ever increasing nuisance for computer users everywhere, but also a booming industry. According to Webroot Software, Inc., the distribution of online advertisements through spyware and adware has become a $2 billion industry.

The aggressive advertising and spying tactics demonstrated by some of these programs, require an equally aggressive response from a seasoned eradicator. Sunbelt Software is such a company. A leader in Anti-Spyware, Anti-Spam, Network Security and System Management tools, they gave consistently remained on the cutting-edge of anti-spyware programming since 1994.

One of their more notable software applications is CounterSpy 1.5. CounterSpy is designed to detect and remove spyware that is already in your computer system. Additionally, it provides real-time protection while preventing browser hijacking and changes to your computer’s Registry.

Other notable features include:

For Your Safety, You Really Need To Know

Just what is Intelligent Explorer?

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!

Computer Security And Security Suites

Before proceeding to read this article, it is important that we state something up front. It is essential for the reader to understand and appreciate that there is no such thing as a secure operating system or web browser. While the use of security suites and other complementing products can significantly reduce your risks, they are not magic wands that you can wave to eliminate 100% of your risk. Any product claiming they can do this should be viewed with great skepticism.

With that being said, let’s talk computer security and security suites. There are numerous ways in which the security of your computer can be breached. The most common threats come from worms, viruses, Trojans, phishing, hackers and crackers. Potential security breaches can come in the form of downloading unfamiliar email attachments, being monitored by spyware, maliciously attacked by malware, or probed through port scanning.

Dshield.org (www.dshield.org), a non-profit company, functions as a “dominating attach correlation engine with worldwide coverage”. In short, they work with people and companies to track, among other things, port scanning violations. Port scanning involves a person (referred to as a hacker or cracker) who attempts to break into you computer through the open ports in your system. Once an open port is located, the individual attempts to collect your personal data or install a malware program into you computer. On average, Dshield.org logs over 1.1 billion reported attempts of port scanning each month. What is even scarier is that this is just based on their program participants. You can imagine how many more incidents are occurring each month to the general population of computer users.

Dshield.org also reports on survival time. Survival time refers to how long it will take before an unpatched PC is attacked or infected. Below is a snapshot of their current operating system breakdown:

Current OS Breakdown
Category % Adjusted Survival Time
Windows 27.0000 128 min
Unix 0.5000 3648 min
Application 3.0000 1203 min
P2P 1.5000 1591 min
Backdoor 0.5000 5432 min
Source: Dshield.org – Survival Time History (11/8/05)


In short, if you have a Windows-based operating system and an unpatched PC, you will be attacked or infected in a little over 2 hours. When looked at in these terms, securing your computer becomes a mission.

Here are a few easy steps you can take to immediately protect your computer.

1. Don’t run unfamiliar programs on your computer.
It sounds like common sense, but many of the most prominent attacks have involved spyware and email attachment worms such as Bagle and Netsky. If you don’t recognize the sender, don’t download its attachments.

2. Don’t allow unrestricted physical access to your computer.
If you have sensitive or proprietary information on your computer, allowing other employees or family members to use your computer can lead to potential breaches in your computer’s security.

3. Don’t use weak passwords.
Use passwords which are difficult for someone to figure out. People frequently use the names of children, pets, anniversary dates, or birthdays. Because there seems to be a password needed for everything, it is not uncommon to see many people using the same password for everything. Big mistake! The use of only one password provides a hacker with easy access to a smorgasbord of personal information. If you have to write your passwords down, it is best not to leave them on a post-it, attached to the screen of your computer. You may chuckle at the absurdity, but it happens more than you think.

4. Don’t forget to regularly patch your operating system and other applications.
Many industry experts believe that most network security attacks would be stopped if computer users would just keep their computers updated with patches and security fixes. Too often, we forget to do this on a regular basis. Remember that every day, new viruses, worms and Trojans are being created and distributed. They are looking for the weaknesses in your computer system. Having outdated software is basically the same as holding the door open and inviting them in for a visit.

5. Don’t forget to make regular backups of important data
Always keep a copy of important files on removable media such as floppy/ZIP disks or recordable CD-ROM disks. Store the backups in a location separate from the computer.

In most cases, Windows desktop and screen-saver passwords provides adequate protection for normal security concerns. However, if you feel more comfortable taking additional security measures consider obtaining a comprehensive security suite.

Selecting a Antivirus Software
The next question is how do you pick the best product for your needs? You start by asking yourself a series of questions. Do you need password protection for individual files, your desktop, a network, or to block someone’s access to the Internet? Is your computer used only by you or do multiple users have access to the computer? How many users in total do you expect on your computer? What are your system requirements? How much do you want to spend?

Once you are able to answer these questions, you can begin to research which security suite will best meet your needs. Product reviews and user statements provide a great starting point. PCMagaine (www.pcmag.com), Zdnet.com (www.zdnet.com), and Consumer Reports (www.consumerreports.org) are just a few informative sites that offer research on various computer software products.

There are numerous security suites available on the market. Take the time to choose the one that meets your specific needs. As a starting point, we’ve listed a couple of the more popular programs:

1. Kaspersky Personal Security Suite
