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?

Signs of a Computer Infection!

So I was thinking this morning what I missed and I totally missed on how you might be able to tell if you have a computer virus. It does me no good to talk about a virus if you don’t know you’re infected. I was thinking of the times I had a client who had trouble but wasn’t what I thought.

So How do you know?

Some people would say it depends on factors but here are what I call clues that make me suspect a virus:

1. Slow or Sluggish computers –  Here is what I know if the computer is really slowing down and have a dual core or quad core.  If you are running a system and sees a lot of hard drive activity even when the computer is idle then it might be a virus or it could be a program doing what it is supposed to be doing.  So this is somewhat of an indication but not always.
2. Slow internet connection on the computer or on the network — Due to the fact that most people have a router that is connected to all the computers and if you internet connection on all your systems are slower than normal then you could have a virus.  I use Speed Test website to help determine this.

Uncovering a Virus/Trojan

Getting done with the first part really got my juices flowing. I was shopping looking and thinking about this next article. I came up to only one option turning this into a 3-5 length post due to all the content that I will have.  So where did we leave off?  Oh that is right figuring out if you have a virus/Trojan.  The instant I made a post about this 12 hours later someone make a comment and here is what he said:

I can’t wait to read part two of this article. I always wondered how you’d know you’re infected if a virus don’t want to be detected and no virus definitions are yet available, because the virus is so new.

Now the truth is anytime a Virus does something it usually leaves a footprint somewhere and somehow.   Even the hardest working hacker can’t plan for all possibilities and that is where we begin.   I have been helping people for a while with viruses and know that no matter how hard the virus tries to hide you can usually find it relatively quickly and easily do to virus check here are the ways I’ve done to figure out if they may or may not have a virus/Trojan.

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.
