Disaster preparation 101 — Data backup

In this one I will talk about Disaster, it happens to all of us from time to time. A fire, a earthquake, a stolen laptop or any number of ways. So what happens to your data, is it stored on the laptop? Is it important very sensitive data? Could you get fired if you lost that data?

These are all questions you must ask yourself when you have laptop. How do you backup your data or even do you have a backup? Having seen this with my own clients, I must wonder if there are people out there who just don’t care. I had a client the other day who gotten a virus and this was a really mean virus. Deleted some very important files when you tried to clean the virus out. She called me in a panic because she couldn’t load up windows? I asked if she had any backups, she said “what’s a backup” . So I sat there discussing this with the client for over 20 minutes. Finally she started to understand, she said she had the OEM Backup DVD but nothing else. She also said she needed help with getting data off the computer. I told her that I would be able to come the next day and I was lucky the virus didn’t do anything else to her data. We were able to retrieve the data from her system. That is where I start my rant , Why would anyone not have backup of there most important data?

What is a Virus and Why do I have one

After seeing more and more the updates coming from the net.  I wanted to talk about what a Computer Virus or Trojan is and how you get it.   So how did  you could of gotten a Virus in the first place.   So here are some information to consider:

The vulnerability of operating systems to viruses

So what does that mean to you?  Most of the times when you get a virus you have a vulnerability in some place in your Operating system and it is either something that has not be known by Microsoft, Apple, and Linux or is know as a Zero-day Exploit.

A zero-day (or zero-hour) attack or threat is a computer threat that tries to exploit unknown, undisclosed or patchfree computer application vulnerabilities. The term Zero Day is also used to describe unknown or Zero day viruses.

This is one of the most used because if it is an unknown exploit by the Operating System creators then they have a longer to us the exploit.  Most of the time hackers like to use this because that means there is a possibility of finding even more vectors to infect other systems.  You see if they can get on one system they can then find ways to get on other systems.

How to disable autorun the easy way!!!

I read a report from Cnet about USB devices spreading Virus and I will quote:

The bad guys are intentionally developing new flavors of malware designed to propagate through USB devices,” said Gunter Ollmann, chief security strategist for IBM’s ISS security division. “They are today’s floppy drives.”

An infected computer can spread a virus to a clean USB thumb drive that is inserted. That USB drive will then be spreading the virus onto other computers if the operating system on those machines has an AutoRun-type feature enabled. The AutoRun function in Windows launches installers and other programs automatically when a flash drive or CD is inserted. The Mac has an equivalent function, according to Ollmann.

In order to disable “autorun“, which in Vista is called Autoplay. In order to disable Autoplay from starting when you insert media into your computer here is how you do it:

You will need to be Logged in as Administrator before this can be done:

Next click start and type “Autoplay” without quotes. It will bring up a screen but all you have to worry about is this:

Fake Wordpress update 2.6.4 steals data!

The hacked version of the file pluggable appears to be stealing the content of cookies on larger installations of WordPress. Sophos are now detecting this file as Troj/WPHack-A.

Apparently this little update is a rogue update.  According to Sopho’s and Craig Murphy’s blog, it is said to steal your data and send it to another site.  This hacked version of Wordpress is coming from wordpresz.org so if you happen to stumble onto this fake update, just delete it and go on with your blogging.   Craig talked about how when he logged it this fake update popped up.  So sometimes it is safer to do some digging before you apply an update especially to your Operating system.  Thanks to Sopho’s for telling people about this fake and dangerous problem.

Windows update is getting a revision!

According to Computer World, dated Oct 31, 2008 and I’ll quote:

“Over the next couple of months, we’ll be rolling out another infrastructure update to the Windows Update agent (client code),” said an unidentified Microsoft employee on the Windows Update team’s official blog. “This update makes it possible for users to install more than 80 updates at the same time.”

Now if your like me and have several computers who need to be updated at a given schedule, you sometimes worry about these updates that come along that might just break your system. I have been using a program call Offline Updater, which does what Autopatcher does really nicely. So why is Microsoft sending out this patch? Two reasons, one they want you to be able to update your operating System without hurting your system integrity.

Now lets talk about the integrity of having to reboot your system. You see, every time you reboot the system, it causes the system hardware some strain.  It is something like having starting up a car, sooner or later you will have the starter go out, because of to much start up.

Running old programs on Vista (tips and tricks)

So We’ve talked about how to get Vista to shut down better.  So I thought we talk about getting Windows XP programs to run on Vista and be more stable.  You can do this with Windows XP, ME, 2000, NT,. and 95 programs.

• Run the program in compatibility mode – This is something Vista comes with now for running old programs in Vista. To do this you will have to do some minor things.  Go to where the program is and right click on the program.  Select properties>compatibility.  Select “Run this program in compatibility  mode for:” Select  windows Operating System that you think would work with the program.

• Run the program as Administrator –  This is a really good tip and trick to sometimes get programs to run with vista.  It goes hand in hand with the last one.  Right click on the program and select “Run as Administrator”.  I find some old programs don’t know about the kernel protection in Vista and you need to give them permission to use the kernel for the program to work.
