Just What The Heck Is Spyware, Anyway? (Page 1 of 2)
What Is Spyware? It goes by different names. Spyware, adware and malware are some of the more popular monikers. It really doesn’t matter what you call it, though. The bottom line is that you don’t want it on your computer. First of all, let me state for the record that I think the internet is a wonderful thing. I think a majority of people would agree that the World Wide Web has made life for all of us a little more convenient. Whether it’s reserving a hotel room, buying music online, checking the local weather or any number of thousands of useful sites (did I mention email?) we all have gotten a little bit spoiled with having all this information right at our fingertips. That being said though, sometimes we seem to get a little complacent and let our guard down. We forget that the internet has a seedy side full of ways for unscrupulous people to con honest (if not a little niaeve) people out of their money (or worse!). In this article, I’ll cover a few of the pitfalls that many people tend to have trouble with.
Adware: This type of malware is designed to do one thing and one thing only. Get you to buy something. Once this type of software has infected your computer, you will start getting a lot of pop-up ads. Sometimes these ads are the pop-under type. Pop-under’s get by any pop-up blockers by generating an ad without stealing the focus from the web page that your viewing. You usually won’t even know it’s there until you close your browser and see the ad (or ads) displayed on your desktop. Generally, this type of malware is little more than an annoyance, but sometimes multiple instances can cause major slowdowns in your PC or even cause system crashes. Adware is usually bundled with some other “free” software such as free desktop wallpaper, icons or screensavers. It may or may not be disclosed in the end-user license agreement (EULA) of the free software, but even when it is, most people never read those agreements anyway. If you want to protect your computer from this type of malware, you should ALWAYS be suspicious of free software.
Spyware: Spyware does exactly what it’s name implies. It spies on you. Well, actually it spies on your web surfing and purchasing habits. The information that is collected is usually then sold to unscrupulous vendors who target you with spam email. Again, this type of marketing is usually just an annoyance, but anytime your privacy is compromised (especially by some sleazy dirtbag who will do anything to make a buck) there is cause for concern.
Trojan Horses: Sometimes simply known as “Trojans”, these, in my humble opinion, are the worst offenders. If you know the story of the Trojan War, then the name given to these vicious baddies will make perfect sense to you. Here’s the way it works: You are happily surfing along the internet, minding your own business, when all of the sudden a banner pops up and cheerfully anounces that you have won a FREE IPHONE (or a free laptop computer, or a free vacation, etc.). All you have to do to claim this generous prize, it seems, is to “CLICK HERE!”. Trust me on this one, do not ever, EVER, “CLICK HERE!”. BIG MISTAKE! What you’re doing with that click, is allowing malware to be downloaded to your computer that will make your life miserable and, as an added bonus, you’ll never get your free prize.

Computing's Dirty Dozen: Malware (Page 1 of 2)
It seems that no sooner do you feel safe turning on your computer than you hear on the news about a new kind of internet security threat. Usually, the security threat is some kind of malware (though the term “security threat” no doubt sells more newspapers).
What is malware? Malware is exactly what its name implies: mal (meaning bad, in the sense of malignant or malicious rather than just poorly done) ware (short for software). More specifically, malware is software that does not benefit the computer’s owner, and may even harm it, and so is purely parasitic.
The Many Faces of Malware
According to Wikipedia, there are in fact eleven distinct types of malware, and even more sub-types of each.
1. Viruses. The malware that’s on the news so much, even your grandmother knows what it is. You probably already have heard plenty about why this kind of software is bad for you, so there’s no need to belabor the point.
2. Worms. Slight variation on viruses. The difference between viruses and worms is that viruses hide inside the files of real computer programs (for instance, the macros in Word or the VBScript in many other Microsoft applications), while worms do not infect a file or program, but rather stand on their own.
3. Wabbits.Be honest: had you ever even heard of wabbits before (outside of Warner Bros. cartoons)? According to Wikipedia, wabbits are in fact rare, and it’s not hard to see why: they don’t do anything to spread to other machines. A wabbit, like a virus, replicates itself, but it does not have any instructions to email itself or pass itself through a computer network in order to infect other machines. The least ambitious of all malware, it is content simply to focus on utterly devastating a single machine.
4. Trojans. Arguably the most dangerous kind of malware, at least from a social standpoint. While Trojans rarely destroy computers or even files, that’s only because they have bigger targets: your financial information, your computer’s system resources, and sometimes even massive denial-of-service attacks launched by having thousands of computers all try to connect to a web server at the same time. Trojans can even
5. Spyware. In another instance of creative software naming, spyware is software that spies on you, often tracking your internet activities in order to serve you advertising. (Yes, it’s possible to be both adware and spyware at the same time.)
6. Backdoors. Backdoors are much the same as Trojans or worms, except that they do something different: they open a “backdoor” onto a computer, providing a network connection for hackers or other malware to enter or for viruses or spam to be sent out through.
7. Exploits. Exploits attack specific security vulnerabilities. You know how Microsoft is always announcing new updates for its operating system? Often enough the updates are really trying to close the security hole targeted in a newly discovered exploit.
