Web junk
By George Horton
Just because you have cookies on your computer doesn’t mean it’s hungry.
Cookies are simple text files that identify your machine, much like a barcode.
You get cookies when you land on most websites in the course of your browsing.
They are useful in letting websites remember who you are and what you did the
last time you visited.
Although adware and spyware can make use of cookies, they are not related.
Adware (software designed to deliver ads, pop-ups, etc.) and spyware (software
designed to monitor your Internet usage and report back to a central computer
without your knowledge) generally make their way into your computer inside of
other programs. Some software authors generate revenue by making a deal with an
adware or spyware companies to silently install their software during the
installation of the primary program. For instance, if you install a desktop
program that constantly tells you what the weather is, (not only does it use
valuable computer resources thereby slowing down your machine), it also installs
a program that allows it to send you ads. (The End User License Agreement (EULA)
covers what happens when you install the program, but most users simply click on
the 'I agree' button and go on with life). Another way developers get you is to
use pop-ups that look like error messages that want you to click on the message.
It will then give you instructions on how to fix the error and in so doing get
you to install an unwanted program.
These sirens of the web can be very confusing to new users, and even power users
get caught when they let down their guard. A new and I think unethical method of
secretly installing adware, spyware and malware on computers is what they are
calling a “drive-by download”. Just by visiting an unscrupulous website with lax
security settings on your computer, a program can be installed without your
knowledge. Anyone that has a Web site can 'tickle' the visitor's computer to see
if it is vulnerable and if so, silently place a program on the unsuspecting
visitor's hard drive. Fringe Web sites that deal in illegal music downloads,
adult content, gambling, hacking, cracking, or any grey area content, are
notorious for drive-by downloads. Please use a firewall. I recommend Free
Zonealarm at www.zonelabs.com , and you should make sure that your operating
system is up-to-date by going to http://windowsupdate.microsoft.com/ on a
regular basis. Mac users can go to http://apple.com/support/ .
No matter what you do from a security standpoint, your system will pick up
adware and spyware programs, so you need a program that can track down and
remove these malicious installations. I recommend Free Ad-Aware from
www.lavasoft.com . If you are a power user you might try Spybot search and
destroy. I do not recommend it for novice users though.
When you buy a new computer you download software like there's no tomorrow, then
you notice a lot of icons in your system tray, (bottom right corner of desktop
toolbar). These programs start up every time Windows does. There are problems
associated with that like; they take up system resources, (RAM, Processor speed,
slowing down your computer, etc), and slower boot up time. You can take control
however by looking for an option in the program itself that will allow you to
turn off the automatic startup, and delete the program shortcut from the Windows
Startup folder. (Start-All Programs-Startup-the program)
Want to have your cake and eat it too? Here are some applications that are the
equivalent replacements for the Microsoft version of the product. Not only are
they free, but they are also better in some areas. Internet Explorer =
www.mozilla.org/products/mozilla1.x/ or
www.mozilla.org/products/firefox/ ,
Outlook Express = www.mozilla.org/products/thunderbird/ , Microsoft Office =
www.openoffice.org/ , MSN Messenger = Trillian Basic at
www.ceruleanstudios.com/downloads/ .
You can also replace Windows by using Linux. Linux is an “open source” operating
system that has a couple of different flavors; Mandrake at
www.mandrakelinux.com/en-us/
provides an easy-to-use version of Linux, and if you would rather have a copy of
Linux on CD to look it over before installing, go to
www.Knoppix.net . Look for
Lindows coming soon to a screen near you.
You have no doubt been hearing about “Voice over IP (VoIP). Here is a free
program called Firefly at http://www.freshtel.net/?show=home/ that integrates
instant messaging and VoIP. The program is easy to use and install. After you
install Firefly, you register for your own phone number that others can use to
call you. You have the option of publishing the number in the firefly directory.
On top of this, you also get a fully featured voice mail service. A great
program for those who want free worldwide calling.
As always, surf safe out there
