We recommend that you take the following action:

• Notify all your email users about this threat
• Caution your users not to open any attachments from DHL or any unknown sender
• Be aware that this is a rapidly-changing virus. Even if your anti-virus provider lists it as covered, you may still be at risk. We will update our clients when we feel this is no longer a threat.

More information about this threat:
The messages have their “From” field spoofed to appear as originating from an DHL email address. The subject is “DHL Tracking Number ########” (where # stands for a random letter or digit) and unlike most spam, the content of these emails is relatively well-spelled.

The message, signed by DHL Delivery Services, reads: “Hello! The courier company was not able to deliver your parcel by your address. You may pickup the parcel at our post office personally. The shipping label is attached to this email. Please print this label to get this package at our post office.

The attached archives are called DHL_INVOICE23.zip and contain a trojan installer. “The file in the ZIP archive uses a double file extension in the form of DHL_INVOICE_23.xls______________<plenty of underscores>______.exe,” the Avira researchers explain. This naming scheme as well as the file Excel document icon, have the purpose of deceiving the users into believing that they are actually opening a document.

The series of underscores pushes the .exe extension out of the view when the archive file is opened in an unpacking program. At the same time the .exe part will not be visible in Windows Explorer either, since file extensions are hidden by default.

Thanks to Martin and Heidi from Doyles’ Physio Therapy in Pyrmont (http://www.doylesphysio.com/), who has given permission to copy these tips into our computer tips email.

1.  Sit in a good quality, adjustable chair. Pull your chair close to your desk, adjust the seat height so your elbows hips and knees are at 90 degrees. Forearms should be parallel or sloping down the desktop and feet should be on the floor.
2. Adjust your chair’s back support, so it is in the lower part of your back near your hips. It should gently tilt your pelvis forward.
3. Have the screen straight in front of you at arm’s length away.
4. Ensure your screen is easy to see. Make sure there are no light sources behind it, and tilt the screen to eliminate reflections.
5. Don’t use a laptop for extended periods. If you must plug in a full sized keyboard and mouse.
6. Limit continuous computer use. Take breaks every 30 minutes and do neck and shoulder stretches – shoulder rolls are great! Focus on a distant point to give your eyes a break. Get up and walk around hourly.
7. Take notice of early warnings. If you feel and ache or discomfort in any part of your body, check your posture, take a break and if the problem persists see a physiotherapist.

Cheers until next week!

Once you turn on Login Notifications, the next time you log into your Facebook account you will be asked to add this computer to the list of trusted computers to login from.

After adding this computer you will receive an email from Facebook notifying you of the newly added computer.

So, now when you get an email notification that a new computer has been added and you know you did not add this computer yourself you can then login to Facebook and quickly change your password to prevent unauthorized access. Remember to use a complex password as an account with a weak password is easily broken into.

Hopefully something you do not have to touch. Well that is unfortunately not the case. Per some studies that were done your mouse and keyboard holds more germs than a toilet seat or  door knob. To be more specific, tests done shows that keyboards hold 3,295 germs per square inch, compared to a toilet seat that holds 49 germs.

Here is an article I found on cleaning a keyboard, covers a basic clean or even declaring all-out war on the germs!

Note: I would not remove the keys on a laptop keyboard, only because they are easily broken.

1. Right-click on the program you want to create the keyboard shortcut for and select Properties.
2. Click in the Shortcut field and press a key on your keyboard. I created an iTunes keyboard shortcut and used the letter i. You will notice that Ctrl + Alt becomes part of the shortcut.  This cannot be changed.
3. Once you are done click on the OK button at the bottom.
4. Now when I want to open iTunes I simply press Ctrl, Alt and i all at the same time.

So how much RAM is a sufficient amount? Well it depends on what operating system you have and what you use your computer for. Here are a couple of guide lines:

• If you are running Windows XP, then 1Gb is recommended
• If  you are running Windows Vista or Windows 7 then 4GB is recommended
• If you are running any specialized high-intense graphic program then add another 1GB. You can also check the system requirements of the program you are using (usually on the box or on the website you downloaded it from)

Now how do you find out how much RAM you have in your computer?

1. On your keyboard hold down the Windows logo button and press Break
2. This opens the System Properties page. Locate RAM or Memory. See below for an example.

If you have less RAM than we recommended above, you can get some more installed by a computer technician.  If you are in Sydney, call 9572 7571 and let us know you need more memory.
