New Backdoor Trojan Kills Windows Boot Process

[Lucretia]

Could it be a scary one virus or what ! Do you all have any suggestion regarding this ..
"A recently discovered backdoor sample (detected as Backdoor:Win32/Yonsole.A) can accept and execute a command from a remote server to modify the Master Boot Record (MBR) on the affected machine," Feng said. "The modification to the MBR is like the old "Stoned" virus for DOS. However, in this case, the MBR does nothing but display a banner in the center of the screen and freeze the PC. We detect the new MBR as Trojan: DOS/Yonsole.A.

Please share your ideas .It would be really appreciated ...

Take the following procedure that would be helpful to restrict the infection on your system :

1- Activate the firewall on your system.
2- Download the recently released computer updates for all your installed software.
3- Go for the up-to-date antivirus software.
4- Limit the user permissions on the system.
5- Use caution when browsing the attachments and getting file transfers
6- Go through the caution when clicking on the links to the Web pages
7- Ignore the downloading of pirated program.
8- Secure yourself against the social engineering attacks.
9- Configure the strong passwords. PWDhash for Firefox

Yonsole are able to infect popular, mainstream versions of Windows based operating environment --XP, Vista, and Windows 7--by dropping a DLL within the C:\Windows\System32. The trojan can also dump the DLL within the C:\Winnt\System32 on system working on the Windows 2000 and NT. Yonsole was actually discovered earlier the current month, so most Anti-virus programs--as well as Microsoft Security Essentials--should already facilitate with the protection.

A virus is a virus,There is no matter the way through you put this . They all commonly do the same thing - mess with your copy of Windows, not moving any deeper than the Hard Disk. Until the day come up when anyone got a method to get past the Hard disk/Software level and truly embed a virus within the RAM or BIOS, I am absolutely happy. Besides, you should not really have to worry as long as you are not performing anything invalid or watching other like that .

I do trust a while back I found a virus before which did the same as that. It was early on when mobo makers started working with the flash for the storage procedure of the BIOS. Currently , they are running with a removable chip which you are able to replace (or high end systems with two different copies of the BIOS) in the event which you have flash improperly, or heaven forbid, another nefarious virus figures out a absolute method to clean this out on you. Back then, the virus commonly shelled your motherboard and you had to get a new one.

fix = fdisk /mbr

Not necessarily proper in all cases . If the computer is still infected, repairing/replacing the mbr would not matter as when you start back into the windows and it could just again infect your computer functionality again.

Absolutely, but that would at least allow you to launch an antivirus software and find out the dll. That ignores running to clean out your drive and lose the entire thing.
