1) As soon as you notice you are infected, unplug your internet connection or turn off your wireless.  This will prevent the infection from spreading, and will isolate the offending program from its source.

2) Boot into Safe Mode

3) Run your favorite antivirus/anti-malware program.

This post is really about Safe Mode – how do you get there?  There are a couple of ways depending on the operating system you are using.  Here’s the Microsoft Page on the topic.

Windows XP

If XP is the only operating system installed on your computer, boot into Safe Mode with these instructions.

• If the computer is running, shut down Windows, and then turn off the power
• Wait 30 seconds, and then turn the computer on.
• Start tapping the F8 key. The Windows Advanced Options Menu appears. If you begin tapping the F8 key too soon, some computers display a “keyboard error” message.  If this happens, resstart the computer and try again.
• Ensure that the Safe mode option is selected.  If you are trying to clean a machine that is virus laden, choose Safe Mode Without Networking.
• Press Enter. The computer then begins to start in Safe mode.
• When you are finished with all troubleshooting, close all programs and restart the computer as you normally would.

If you don’t want to bother with function keys, you can use the System Configuration Utility method.

• Close all open programs.
• Click Start, Run and type MSCONFIG in the box and click OK
• The System Configuration Utility appears, On the BOOT.INI tab, Check the “/SAFEBOOT” option, and then click OK and Restart your computer when prompted.
• The computer restarts in Safe mode.
• Perform the troubleshooting steps for which you are using Safe Mode.
• When you are finished with troubleshooting in Safe mode, open MSCONFIG again, on the BOOT.INI tab,  uncheck “/SAFEBOOT” and click OK to restart your computer.  THIS STEP IS CRITICAL.  If you don’t change this back, then the computer will continue to boot in Safe Mode until you do.

Windows 7

Safe Mode in Windows 7 is basically the same as XP – use F8 to get to the Safe Mode startup screen.  MSCONFIG is slightly different – Safe Mode is called Safe Boot, but otherwise the process is the same.

1) Use Friends lists to group your friends into logical groups.  This allows you to grant different access rights to different groups of people.

2) Remove yourself from Facebook search results.  Like the author, my family is chock full of teachers.  For the most part, they don’t want their students to randomly find their personal information from a Facebook search, but still want to be on Facebook for family and friends.  The solution?  Remove yourself from Facebook search results.  You do this from the “search privacy settings” page.

3) Remove your Facebook self from Google search results.  As you know if you Google yourself (doesn’t everyone do this?) your Facebook profile will come up pretty quickly.  You can remove yourself from Google searches from the “search privacy settings” page – uncheck the “Create a Public Search Listing for me …” check box.

4) Control who sees your tagged photos – You can do this from your profile privacy page.  The cool thing is if you’ve set up your friends groups right, you can allow access to tagged photos by group.  That way the photo of you that you don’t want your boss to see won’t get you fired.

5) Control who sees your photo albums – as with tagged photos, not all pictures are for all eyes.  Check out the Photo Privacy Page.  From there you can control who sees what.  Very handy.

6) Control how your relationship status is displayed in news feeds.  Everyone likes to tout their relationship, but do you really want everyone (boss, business contacts) to know?  Uncheck the “Change relationship status” box on the News Feed and Wall section of your Privacy settings.  This will prevent people from seeing changed to your relationship status in their news feeds.

7) Be sure that applications don’t publish embarrassing news feed posts.  Many applications you sign up for post items to your news feed that are potentially embarrassing.  Be sure that you scan your profile every time you install an application, or better yet, avoid applications completely.

8) Control who sees your contact information.  If you use Facebook for business and for personal contacts, you can control who sees what contact information from you using your Friends Groups.  You can add multiple email address and phone contact items, then edit the custom privacy settings for each to control who sees them.

9) Avoid embarrassing wall posts.   Facebook lets you control not only who posts to your wall, but also who can see those posts.  In the Profile section you can change who posts to your wall by choosing “custom” from the “Wall Posts” drop down.  From there you can use your Friends groups to control who posts and who sees what.

10) Like your hands, keep your friends to yourself.  I love seeing who is friends with my friends, but some people don’t want to share, and in some cases, it’s probably not a good idea to share.  Once again, you can customize who can see your friends list using your friends groups.

There are endless ways to control your privacy on Facebook, but you need to take the time to sort through the settings.  Friends Grouping is a great place to start and ensures that you have separation of your business and personal contacts.  Get to know your privacy settings!!

There are lots of methods to use to secure your wireless network.  The most common is WEP, but that is being replaced by the newer (and better) WPA protocol.  You can also secure the network by allowing only specific computers on the network.  This is simple to do, and doesn’t require security keys and messy settings.  The problem with it is that the data you send wirelessly is not encrypted.  With WEP and WPA, the data is encrypted.

What are these things anyway?

WEP or Wired Equivalent Privacy (see the Wiki for more info) is an encryption protocol developed in the late 1990’s to secure wireless networks.  It offers 64bit and 128 bit encryption using a key generated by a passphrase you enter, but is easily cracked.  Despite this, there are a ton of people who still use WEP since it is the default protection on many routers.

WPA (WiFi Protected Access) is the next generation encryption algorithm that replaced WEP.  WPA uses 256bit encryption keys, and is far more secure than WEP.  It’s not the be-all-end-all, but is very good.  As with WEP, you have the option of generating a security key using a passphrase so that you don’t have to remember a string of random hex digits.  This is great, BUT you have to be careful about the passphrase you use.  DON’T use things like your pets name, your kid’s name, your street, or anything that can be guessed.

The clear answer is to secure your network with WPA.

BUT – do you have to secure your network at all?  The safe answer is yes.

What happens if you don’t secure your network?  That depends on where you live, how close your neighbors are, and how you secure your computers.  Most wireless routers have a range of 150 feet.  That means that if your neighbors are more than 150 feet away, they will not be able to get on your network unless they are standing outside your house with their laptop.

If you don’t change the default security settings on your computers, chances are that even if someone did get on your network, they wouldn’t be able to do much.  By default settings I mean:

• No shared hard drive locations
• Remote control disabled
• Firewalls up and running on every computer
• Anti-Virus up and running on every computer

Of course, this is not always realistic – I have lots of shared directories, and remote control enabled on my machines because I like to be able to work on any machine from anywhere if I need to.  For that reason, I like to secure the network so that if someone manages to get on they won’t get to my personal files.

The bottom line on security for wireless networks is best practice is to secure your network using WPA.  That said, if you live in a remote area where no one will likely be in range of your wireless, it’s not really necessary, just a good idea.

The panic over this and other worms like it makes me mental.  Don’t get me wrong, these things can cause all kinds of havok not only in terms of potential identity theft, but also tons of lost hours to clean infected machines.  But if you pay just a little attention to security you’ve been innoculated against this and other threats like it for months.  Way back in October 2008 Microsoft released patch MS08-067 to close the security hole that conflicker exploits.  This was an out of band update, meaning Microsoft released the patch outside of the normal monthly patch release because it thought the release was critical.  I know that at my firm, we took this very seriously and had every node patched within two weeks, then made the patch “autofix” meaning that any node that connected to the network would get the patch automatically.

Getting rid of this worm is a pain in the ass if you have it, but protecting yourself from the exploit, which effectively makes the thing benign, is really easy.  Run Windows Update!  If you are infected, there are lots of resources to get rid of it.  Most decent anti-virus programs will get rid of it – McAfee, Norton, AVG, etc.  Google conlicker and you will get tons of help.

I hate the way the media jumps on these things and makes people panic for no good reason.  When did the news become just fear-mongering?  And what good does that do for anyone?  I suppose rasing awareness of malware is ultimately a good thing, but do they have to make it seem like the world is coming to an end?

Patch your system and you are fine.
