Hi there, I've read up on many threads here to try to solve this problem but I am having no luck. I installed windows new on a new hard disk which the partition was deleted and created again using windows cd, I have NOD32 and its reporting I "MBR sector of the 0. physical disk Win32/Mebroot.mbr trojan" I have run Malware Anti-bytes but it does not detect anything tried the NOD32 ESET Mebroot Remover it detects MBR rootkit (Win32/Mebroot) on my system but does not let me remove it, it says unable to clean. Used SuperAntiSpyware but it doesn't detect it either, used SpyBot Seek and Destroy but doesn't detect anything either.

I can't get RootRepeal to work, everytime i try to run it my system just restarts it self..

I have attached a report from GMER which doesn't find no rootkit either.

This is my report from DDS

I've found the fix for this just incase anyone has this problem. "MBR sector of the 0. physical disk Win32/Mebroot.mbr trojan" shows that the problem is in disk 0. I have 3 hard disk's in the computer and I got error messages "MBR sector of the 0. physical disk Win32/Mebroot.mbr trojan" and "MBR sector of the 2. physical disk Win32/Mebroot.mbr trojan" constantly after Windows re-boot. I followed

From Wilders security forumThe following should erase the contents of a USB flash RAM drive, including the master boot record and its associated partition table of data located in the first sector.

1. Open a Command Prompt (filename: CMD.EXE) in Windows. If you are running Microsoft Windows Vista or Windows 7, you will need to open an elevated command prompt.
2. Start DiskPart (filename: DISKPART.EXE), the command line disk partitioning tool. The DISKPART> will appear.
3. At the DISKPART> prompt, type "LIST DISK" (without quotes) and press enter. A list of currently-mounted disk drives will be displayed. Your USB flash RAM drive will show up with a number like 1, 2, 3, 4 and so forth.
4. At the DISKPART> prompt, type "SELECT DISK n" (without quotes), where n is the number of USB flash RAM drive and press enter. Assuming nothing has changed on the system, you would type "SELECT DISK 6"
5. At the DISKPART> prompt, type "CLEAN" (without quotes) and press enter. This tells DiskPart to zero-out (write 0's) across the entire disk. It may take a few moments for the operation to run, depending upon the capacity and speed of your USB flash RAM drive. When finished, you will have an empty USB flash drive.

At this point, you can type "EXIT" and press enter to quit, however, if you would like to format the disk or make it bootable (for a Windows Vista or Windows 7 installation), you can do so by following these steps:

1. At the DISKPART> prompt, type "CREATE PARTITION PRIMARY" (without quotes) and press enter. This creates a primary disk partition utilizing all of the flash RAM drive's capacity.
2. At the DISKPART> prompt, type "SELECT PARTITION 1" (without quotes) and press enter. This tells DiskPart you wish to perform operations on the partition (disk volume) you just created.
3. At the DISKPART> prompt, type "ACTIVE" (without quotes) and press enter. This tells DiskPart to make the disk partition startable, e.g., allows an operating system to be booted from the partition.
4. At the DISKPART> prompt, type either one of the following commands:
* "FORMAT FS=FAT32 QUICK" (without quotes) and press enter to format the USB flash drive using the FAT32 file system
* "FORMAT FS=NTFS QUICK" (without quotes) and press enter to format the USB flash drive using the NTFS file system.
It may take a moment or two to perform a quick format.
5. At the DISKPART> prompt, type "ASSIGN" (without quotes) and press enter. This tells DiskPart to assign the first available drive letter to the partition (disk volume) you just created on the USB flash RAM drive.
6. At the DISKPART> prompt, type "EXIT" (without quotes) and press enter to exit the DiskPart program.

You should have now an USB flash drive which is empty, but can be used as installation media for Windows Vista or Windows 7, should you decide to copy the contents of an installation DVD over to the drive and later use it for that purpose. Making a USB flash drive bootable for installation is done using the BootSect command on the Windows installation disc, but that's getting a little outisde the scope of this discussion, which was how to remove Win32/Mebroot from the USB Flash RAM drive.


Hope this helps anyone else :(

Hello.

Thanks for letting us know.

Below are some prevention tips.

Preventing Infections in the Future

Please also have a look at the following links, giving some advice and Tips to protect yourself against malware and reduce the potential for re-infection:
  • Avoid gaming sites, underground web pages, pirated software sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware.
