There is a new Trojan out there that is poised to disrupt Internet service for hundreds of thousands of users in July.  The Trojan basically invades your PC, disables your current Antivirus, and alters the way your PC interacts with DNS (Domain Name Service) servers.

DNS Servers are the 411 service that your PC uses to talk to other PCs.  People use Domain names (Google.com, Microsoft.com, Apple.com, ToTheRescueDFW.com etc) to describe website addresses.   Computers on the other hand,  talk to each other using IP addresses (72.67.245.201, 8.8.8.8, etc).  Your computer provides a Domain name to a DNS server and the DNS server provides the IP address of that Domain.

The good news is it is relatively easy to determine if you are infected.  Go to http://www.dcwg.org/which is a site run by the FBI’s security partners.  Once on the site Click the Detect button in the upper left of the screen and find out if you are infected. There are tips for removing it if you are infected.  If the steps seem overwhelming, contact To The Rescue and we will be happy to help you.

You may have heard over the weekend about a new malware attack that is targeting Macintosh computers, http://www.upi.com/Science_News/2012/04/05/Malware-on-half-a-million-Apple-computers/UPI-57431333660431/?spt=hs&or=sn.  It is called “flashback” and can give the attackers remote access to your computer.  The Trojan targets a vulnerability in Java, a programming language created by Sun Microsystems who was acquired by Oracle in 2010.

The good news is that the fix is easy to deploy, just go to the Apple symbol which is on the left-side of the menu bar at the top of your screen, and choose Software Update.  Then apply all updates that are made available.  After the updates install (a reboot may be necessary), run the Software Updates again.  If you get a message that your system is up to date, you are done.  If not (boy, you must be behind on updates!) keep running the Software Update until you do get the message.

Java is a programming language that is used by many websites and even computer applications.  It is popular as it is cross-platform (it runs on both Macs, Windows and even Linux machines).  Because of its wide spread usage it is an easy target for virus creators.

Many of us have complained about passwords at one time or another.  Many sites will let you specify what ever you want as a password while others may require a strong password or even assign one for you.  Why do they care?  Truth be told, they are just trying help you.

Passwords are the keys to your electronic world.  There are nefarious people (a.k.a. “turds”) on the Internet who want to gain access to information that is not theirs.  These folks have software that will attempt to hack your account by trying different passwords until they successfully get into your account.  And if your password is easy (e.g using “password”, or “123456″ or “abcdef”) , you stand the risk of being hacked.

Have you ever cursed at those funky character match screens that are on some websites? They are called CAPTCHA and this technology is used to foil automated software that tries to hack passwords or create invalid user accounts on websites.  Currently only humans can match those funky phrases as the phrases are images. So the automated hack tools are foiled when those are used.

I have found a useful site to evaluate how easy your password is to crack.: http://howsecureismypassword.net.  You simply enter your password and the site will compute how many seconds, minutes, hours, days or years it will take for a desktop PC to crack your password.  Go ahead and try it.  If your password can he hacked in minutes, you better change it quickly or you might become a victim.  Test the impact of capitalizing one or more characters in your current password. Or add an additional character to your password and then re-check it.  Or add a special character (e.g. $, # @, !) and see what effect that has.  You’ll be amazed.  A password that can be cracked in minutes can be changed to requires years of compute time to crack them by using those tips.

Now that I have given you a tool, please use it to make sure you have a secure password.  I have also written an article that provides some tips for creating and remembering (this is the key) a strong password that you can remember at: http://totherescuedfw.com/support22/published-articles/18-passwords-and-security.

Please lock the doors to your digital information by using a strong password!  And thank those websites that use CAPTCHA technology to foil hackers.

You might be aware that all cell numbers were being released to telemarketing companies last month.  You know what this means-more calls that you don’t want.  While calls to your land line can be irritating, the only cost is your time.  Receiving calls on your cell phone not only cost your time but can cost you money as they count against your cell phone’s plan minutes.

You can help reduce these calls by calling the National DO NOT CALL list at (888) 382-1222 from your cell phone.  It only takes a minute to sign-up your phone and can stop these irritating calls.

It takes about 30 days until the registration takes affect so sign-up now.

Thank you to the many readers who sent comments on the first issue of “Technology Pulse.” Several of the comments asked for clarification of something in the newsletter.  As I was replying to the emails, it occurred to me there may be others who might benefit from the information in the reply.  The ideal situation would be to have an interactive newsletter that supports a two-way dialog instead of the one-way flow of information that a typical newsletter provides.

I explored several alternatives and the most obvious way to accomplish a two-way flow was to transition to a blog format.  The way a blog works is the writer writes a post to the blog which is equivalent to a newsletter article.  New posts are made in chronological order so the most recent post is the first item displayed and the oldest post is the last item in the blog.

What separates a blog from a newsletter is, it is possible to leave a comment on a blog post.  So if you are not clear about a post or have insight about a post or want to compliment the writer, you click the “Leave a Comment” link that is at the end of each post and leave your comment.  Comments are then viewable by all who read the blog.

To leave a comment on any of our blog posts, you’ll have to be a registered user on the site. Just click the Member Login button in the upper left of any page at http://totherescuedfw.com.  Membership is FREE!  If you are not yet a member, click the “Create an Account” link in the Member Login Dialog box.  Once you create an account, anytime a new post is made to the blog, you’ll get an email advising you of the new post.

Technology Pulse and most other blogs are moderated, which means the blog writer has to read and accept the comment before the comment is actually published and viewable by other readers.  This is to prevent obscene, inaccurate or irrelevant information from being blindly added to the blog.

If you are not familiar with a Blog, don’t worry as we’ll work to make the transition easy for you.  I have written a document that provides Blog basics that may be helpful. You can get it by clicking here

Periodically, I’ll continue to send an email newsletter but the articles in the newsletter will only contain the first paragraph of the new post (article).  The title of the article in the newsletter will be a hyperlink that will take you directly to the blog post.  Once you click the title you can read the entire article (blog post) and any comments that have been made since it was posted.

When you do click the title of this article a new window will open that has this post from the blog.  Notice that above the post title on the left side of the page is a red hyperlink with the name of the next blog post.  If you click it, you’ll be directed to that post.  After clicking it, since you no longer at the latest article of the blog, in the right area above the title there is a red hyperlink with the name of the previous blog post.  These two links can help you navigate forwards or backwards through the blog.

There are other advantages to using a blog besides the two-way dialog capability.  Each blog post is tagged with keywords that are searchable making easier to find information when you need it.  Blog posts will be timelier as they can be posted when the information is available instead of collecting articles until there are enough to produce a newsletter.

Hopefully you’ll like this change and find that it makes the information more useful.  You can always get to the blog by going to http://totherescuedfw.com and click the Blog menu in the upper-right of the page. 

Happy blogging and safe computing!

Most of us at one time or another, have had a problem finding a document or file that we had previously worked on or downloaded.  And it gets more difficult as we store more and more information on our computers. There are at least two things that can help us in this task: organization and system tools. This article will focus on the organizational things we can do to keep our computer files in order.

Both Windows and Macintosh have similar hierarchal structure for keeping information and it was modeled after the file cabinet in your office.  The file cabinet has drawers which contain folders that have a label describing their contents and in each folder there are one or more pages of paper or other things that you want to file away.  Your file cabinet can have penda flex folders that can have one or more manila folders in it to help organize your files.

The computer’s equivalent of a file cabinet is called a Hard Drive.  The Hard Drive has one or more Partitions which are similar to the drawers of the file cabinet.  Most of today’s PC have multiple partitions but only one is available for the user.  The others contain system diagnostics and software to restore your system to its factory defaults. Partitions are named and on Windows PCs they have single letter as a name, like the C drive.  On Macintosh computers theu usually have a longer friendlier name,  like “Macintosh HD”.

In the Partition there are folders that have names that describe their contents.  Inside each of the folders files each with a unique name.  The files can be documents, spreadsheets, photos, movies, system files, programs, et al.  Like your office file cabinet, the folders are used to help organize the contents.  And it is perfectly normal to have folders inside of folders (think pendaflex) if it helps the organization.

Now that you have that background, you can see that you can use organizational techniques for your office to keep your computer files in order.  I ran across an interesting article “File organization tips: 9 ideas for managing files and folders” that gives some helpful tips for organizing your files.  While this article was written by the staff at Microsoft, these tips can be applied to the Mac as well.  See if any can of the tips can help you.

We have heard that Macintosh computers are built different from Windows PCs and they are not susceptible to getting viruses and other malware.  Well that is not totally true.  The fact is there are many more PCs installed in the world than Macintoshes so the hackers have concentrated on wrecking havoc on the PC world as it affects so many more people.

Researchers a F-Secure have identified a Mac Trojan that is making its rounds that is disguised as an inocent looking PDF file.  This trojan is emulating a tactic that has been used by hackers for years to attack PCs.  More information can be found at:

Mac Trojan Spreads

The best advise which is applicable to both PC and Mac users, is don’t open attachments from strangers.

If you are a Vista or Windows 7 user, you may have awakened one morning to find
that your Internet Explorer had changed significantly. This occurred because in
Microsoft’s infinite wisdom, they changed the status of the Internet Explorer 9
update from a “recommended” update to an “important” update. For many users,
“important” updates are installed automatically while “recommended” updates
require user action for them to be installed.

Internet Explorer 9 has significant improvements in performance and security
but the user interface is different from Internet Explorer 8. The most
significant change is the search box in the upper right corner of IE 8 was
removed.

The search box may be gone but the functionality remains. In IE 9, the address
bar functions as both a place to enter a URL and a place to enter a search
term.  If IE 9 determines you entered a search team, it will use your favorite
search engine to do a search.  Otherwise it treats it like a URL and opens up
that website.

Click the link below to watch a short video on that highlights the changes IE 9
has introduced:

Apple restrained from offering a two-button mouse for many years as
Apple believed it was confusing to users. They instead offered context menus
when the Option key is pressed while left-clicking on an icon. When the
context menu is displayed, release the Option key, use the mouse to select an
item off the menu and use the mouse button to initiate the selection.

If you have an Apple Magic Mouse, you can get a context menu by using your
finger to click on the upper right corner of the mouse. If you set-up your
mouse as a left-handed mouse then click on the upper left corner.

There are many other functions the Magic Mouse provides that make it different
from a PC mouse. Click on the link below to watch a quick video that explains
the Magic Mouse operations.
