In the past few weeks a Chinese security company called Qihoo 360 blogged about a new BIOS rootkit hitting Chinese computers. This turned to be a very interesting discovery as it appears to be the first real malware targeting system BIOS since a well-known proof of concept called IceLord in 2007. The malware is called Mebromi and contains a bit of everything: a BIOS rootkit specifically targeting Award BIOS, a MBR rootkit, a kernel mode rootkit, a PE file infector and a Trojan downloader. At this time, Mebromi is not designed to infect 64-bit operating system and it is not able to infect the system if run with limited privileges.

The job of the MBR infection ends here, waiting for the Windows startup which will load the patched executable. When loaded, the payload self-decrypt its malicious code and loads in memory the my.sys driver. Then it tries to download an additional infection from the (now unavailable) URL address: :806/test/91/calc[removed].
And From what Im looking at I first got this from my brother who downloads Flash Video Not sure the site but we all know the kind that would have one rushing in and clicking on a Fake Adobe flash downloader and not questioning why it installed without making you close the browsers fiRst. He had an old HP that was Utterly Infected it had BT and never bothered me untill feb 2 I buy a BT Dongle connected my comp to the phone. And went to sleep woke up at 7next morning choking on smoke with my am on fire And the Half the room Already lit. So again Pleace prove Me wrong id love nothing more and maybe help me clear this all. i welcome any requests for logs Or sample code.
So i took out the infected disk, downloaded the latest bios on a clean PC and saved it on a new usb stick. Booted the infected laptop and went into the bios (with F2 key), started the Easy Flash utily from there and flashed the bios. I attached the infected disk as a usb disk to a clean computer and removed all partitions. Next i placed the empty disk into the laptop and reinstalled Vista from DVD.
Once you've found the Support page, there should be a section for downloads or drivers. Head there and search for BIOS or UEFI updates. Download the latest one and check the included instructions. You'll generally have to go through one of two processes.
Some manufacturers, like HP, will offer BIOS updates through their own software update utilities. This makes it far easier to update, since you don't have to enter the BIOS setup before running the update. Others, such as Acer, will require you to download an EXE file from the manufacturer's site. Instead of rebooting your machine, you can just double-click the update program, and it will run through the reboot-and-update process for you.
