Special Feature: Warning:
Valentine's Day Scams
The
following article is from fraudguides.com.
Valentine's
Day is a day of romance and expressions of love but if you're not careful you
could fall victim to a Valentine's Day scam.
Valentine's
Day Phishing Scams
As
February 14th approaches we come to expect marketing pitches and eCards to arrive in our mailboxes related to Valentine's
Day. Crooks are well aware of this and they use this time of year to trick the
unwary into divulging their personal and financial information. One such phishing
scheme involves an email indicating that the flowers you ordered for your
sweetie won't be delivered unless you log in and re-enter your credit card
What
are the chances that a significant number of these messages are going to reach
people that have ordered flowers? No one wants their loved one to think they've
forgotten them on Valentine's Day! If you click the link in that email and
enter your credit card number you could have a real problem once you get your
next statement. Even if you think a message like this is real, go directly to
the florist's website or call them on the phone.
The
same rules apply all year long. Treat any email message like this skeptically
and always go directly to the website rather than clicking a link in an email
no matter how legitimate it seems.
Online
Dating Scams
As
Valentine's Day approaches many singles turn to online dating websites to find
true love. What many find is anything but. Scam artists often create fake
profiles designed to match a certain kind of person, the kind of person they
think will fall for their ploy. Once they make contact with you the scam
begins. Whether you are chatting in a chat room or instant messages or through
emails it slowly becomes clear that you've hit the jackpot. This new person you've
met is perfect in every way. They have the same likes and dislikes as you and
most importantly, they really dig you.
It's
not hard to see how this works. They let you tell them something first.
Agreeing with whatever you say is simple. Someone that does this for a living
is going to be very good at it so it will be hard to detect unless you are
skeptical by nature. Anyone looking for love online should always be skeptical.
What
happens is that the criminal is slowly grooming you, trying to develop enough
trust in them that you won't notice when they bilk you out of your money. This
attempt will come when it's time to finally meet. Your true love won't have
enough money for the trip and need you to wire funds for a plane ticket.
Another common variation on this scam is that either your online paramour
becomes sick or has a relative or child that needs medical attention. This
works well because themoney is needed quickly and you
won't have time to think about it. Time is of the essence. If you can't help someone
might die.
Use
your head if this ever happens to you. This is a very old and common scam. If
you fall for it you will have to deal with both heartache and wounded pride.
Valentine's
Day eCard Trickery
Be
careful opening eCards on the web! If you have
downloaded all of your patches and feel that your computer is safe you may have
forgotten the biggest vulnerability: you! One message I received directed me to
click a link which took me to a reasonable facsimile of American Greeting's
website. Once there I was presented with a message telling me that I didn't
have the latest Flash player and if I wanted to view the eCard
I would have to install it. I didn't fall for it. For one, the web address or
URL of the website was close but not identical to americangreetings.com and I
pay careful attention to details like that. Second, I am positive that my Flash
player is up-to-date and no phony eCard website is
going to fool me into thinking otherwise. Third, the email message that told me
to retrieve my eCard didn't have my name on it which
tells me that it could have gone out to millions of people in the hopes that a
few might fall for it.
All
of those are red flags. If you didn't pay attention to them and clicked the
link you became the weak link in the security chain and might have installed a trojan on your computer. Trojans
are little programs that can give someone besides you full access to your
computer and the files on it. You certainly don't want that to happen. So pay
attention when you click links like this in your email messages or you might
end up providing a window into your computer that anyone can crawl through.
**********************************
Tips & Tricks: Do Not
Unsubscribe from a Spammer's List!
Once
you have identified a message as spam, don't believe a single word in it, least
of all any unsubscription information it contains.
Spammers
don't remove addresses from their list. If you try to unsubscribe, the best
that can happen is nothing. More than likely, though, you'll get more spam
afterwards, since you have just verified that you do indeed receive messages at
that email address.

Featured Computer Term:
Cookies
Question: Can you explain "cookies"?
What is their use? Someone told me I can delete them as they take up space?
Answer:
A
cookie is a piece of information unique to you that your browser saves and
sends back to a Web server when you revisit a Web site (the Web server is the
computer that hosts a Web site that your browser downloads or sees). The server
tells your browser where to put the cookie on the server. Cookies contain
information such as log-in or registration information, online shopping cart
information (your online buying patterns in a certain
retail site), user preferences, what site you came from last, etc.
The
main purpose of cookies is to identify users and possibly prepare customized
Web pages for them. When you enter a Web site using cookies, you may be asked
to fill out a form providing such information as your name and interests. This
information is packaged into a cookie and sent to your Web browser, which
stores it for later use. The next time you go to the same Web site, your
browser will send the cookie to the Web server. The server can use this
information to present you with custom Web pages. So, for example, instead of
seeing just a generic welcome page you might see a welcome page with your name
on it. This can be very convenient if you shop frequently at a particular
website; the cookie remembers your information such as name, address, credit
card number, and you won’t have to input that information each time you
purchase something.
The
name cookie derives from UNIX objects called magic cookies. These are tokens
that are attached to a user or program and change depending on the areas
entered by the user or program. Cookies are also sometimes called persistent
cookies because they typically stay in the browser for long periods of time.
To
see all the cookies that your browser has stored on your computer, click the
Start button, choose Run, type Cookies in the Run box, and press Enter. Each
cookie is stored as a separate file that includes your username, an @ sign, and the name of the site that stored the
information. You can double-click on any cookie to open its file in Notepad,
and you can use the Delete key to get rid of any cookie you decide you don't
want or need.
Question:
How do you know which cookies to keep and which to delete?
Answer:
You can delete all the cookies if you want. The only thing they do is hold
information about your activities and account information with a particular
website.
For
example if you frequently shop at a specific website, a cookie from this
website identifies you and will include your name and items you might be
interested in when you visit their website.
If
you delete this cookie, the website will show you a generic page and you will
have to log in each time using your username and password before you can access
your account with them. When you order, you may also have to manually type in
your name, address, and any other necessary information that the cookie would
put in for you.
To
delete all the cookies, click Start and open Control Panel. Open Internet Options. On the General tab, click on the button that says Delete Cookies.
If
you’re using Windows Vista, click Start and open Control Panel. Open Internet Options. On the General
tab, in the Browsing history area, click the Delete button. In the next window, click the Delete
Cookies button.

of? Email it to

upcoming newsletter.

Today's Topic: Speed Up a
Slow Computer – Disable Unnecessary Windows Services
As
your Windows computer ages, its speed can decrease. You will notice an increase in response
time when you give commands to open programs, files or folders, use the
Internet and other tasks. There are
several things you can do to speed up your computer.
In
our ongoing series, Speed Up a Slow Computer, we will
present articles discussing some of the steps you can take to speed up your
slow computer.
Important: Before making any changes to your
system, always create a Restore Point.
If anything goes wrong with the changes you make, this will allow you to
revert back to a point when the computer was operating correctly. Please visit our Newsletter Archives to
read our article, All About Restore Points:
http://computerkindergarten.com/html/040509.html
Note: It is recommended to turn off only one or
two items at a time, write down the changes you made, and then use the computer
for several days or a week to make sure everything is working fine. If problems do occur, the items that
were changed can simply be changed back again.
Speed
Up a Slow Computer – Disable Unnecessary Windows Services
A
Windows service is a program that performs specific functions and is designed
not to require user intervention.
This means that the program starts up automatically when the computer is
turned on and runs behind the scenes.
The computer user does not have to do anything to start or work with the
program and, most of the time, does not even see the program running.
Some
of these services are for networked computers, ex. computers in an office that
are connected to each other. They
are unnecessary for the home user.
Turning off these unnecessary services can improve the performance and
speed of the computer.
To
access Services in Windows XP, click on the Start button and open Control
Panel. In Control Panel, open Administrative Tools (If you do not see
Administrative Tools, click Classic view on the left). Open Services.
To
access Services in Windows Vista, click on the Start orb (bottom left) and open
Control Panel. In Control Panel, open Administrative Tools (If you do not see
Administrative Tools, click Classic view on the left). Open Services.
To
see more information about a particular service, click on it. A description of that service will
appear to the left of the Name column.
The Startup Type column displays Automatic, Manual or Disabled. Services marked Automatic start up when
the computer is turned on and remain on and running while the computer remains
on. These are the services that can
be slowing the computer down.
To
stop a service from automatically starting, right click on the service
name. Left click on
Properties. The Properties window
for that service will open. To the
right of Startup Type, a drop down box will display Automatic. Click the down arrow to the right and
then click Disabled. Click the OK
button.
To
determine which services are unnecessary for your computer, visit some of the
websites listed below. These lists
are compiled by Windows experts who have tested computers with and without
these services running.

Important: It is strongly advised to disable only
two services at a time. Note the
services you disable and then use your computer for several days or a week. If there are no adverse effects after
full usage of your computer, go back into Services and disable two more. If you do experience an adverse effect,
go back into Services and change the services you disabled back to Automatic.
