I want to explain and shared my experiences related with technology information from my jobs and my additional experience as consultant. Through this web I want to contribute to the IT community world, then I will be working on recover, build, up load all the information and research that I did the last 20 years ago.
Nice to meet you ! .
You are invited to send your questions and comments related to these issues.

Product : Trojan Virus Part Involved : Security Issue. Summary: A new virus threat has been hidden between MSN chat. Scenario : Chat has changed our daily lives and imagine if that security is broken. Company : Owner. Reference Date : March 2007.
We are exposed to the most strange broadcast virus, it slides quickly between MSN chat conversation in every moment; the impact is very dangerous, because it hides itself behind the MSN chat conversation, then you appearently answer and following the main issue of your MSN chat conversation, when suddenly you receive an invitation to download some file (containing some pictures) adding a text like as "check my pictures taken on some place" and then you are ready to fire the cold chain.
I have seen when you are warn to receive the download file (appearently from your contact or friend) the contact disappear from the contact list (the virus disconnect him or her) while at the same time is inviting you to confirm to download the miracle file. Up to here, you are not consciosnous that you have lost the connection with your contact and you are close to open an unknown file. Imagine That !
In the extreme case when you download that file an execute it then you will notice that you lost the mouse control while the MSN chat window starts to flash and the another application flashs too. Then I recomend this :
1.- Unplug your LAN connection, then you will focus the control of mouse and every thing into desktop.
2.- Reset your computer and boot on safe mode and execute your AntiVirus system as first step
3.- Reset your computer and boot on normal mode and execute too your AntiVirus system as your next step.
The virus is identified as back door trojan and it saves a file named myspace-layout(1).jpg into the cookies and temporal carpets of Internet explorer.
Although I have checked that virus can send message into spanish and english, like as next pictures :
Product : Parameters used into LAN. Part Involved : LAN configuration.. Summary: It is an interesting short procedure to export into a file all the parameters related with LAN configuration of your Pc. Scenario : Adding diversity to use the file exported. Company : National Institute of Cancer of Peru (INEN). Reference Date : March 2008.
I suggest to some people to use next procedure to backup their LAN configuration, if your day to day is necessary changing LAN configuration then fixs you. Then from the command prompt windows (DOS) then type :
netsh dump>C:\IpConfiguration.txt

Following the purpose of my example, I have changed the ip address parameter painted in the above script (mark as blue font), then after saved that, and finally in order to update that configuration, run next command :
netsh exec C:\IpConfiguration.txt
Remember, this procedure is available too into "YouTube Videos hosted by German Medina -at the right side of this page-), like as the next video :
