Hi.

hi all have had a serious of blue screen recently but this seems to be OK now after uninstalling last version of avast clean tool etc

Do you still appears BSOD ?
BSOD can occur only because of faulty hardware or the driver.
Ordinary programs are not cause a BSODs.
You say you removed ( re-install ) the antivirus and the BSOD disappeared?

Then BSOD cause faulty hardware or that I was some malware installed a rootkit on the system (which again is one of the drivers). As I have recently seen not just as badly written malware that causes BSOD’s, I’d started from the fact that your hardware is defective.

Now…abaut your MBR. No traces of TDSS or MBR rootkit.
But you have non-standard MBR on other drive.
We can solve this ( replase standard Windows MBR ) but I doubt that this will solve your problem.

I recommend to you to test your machine,reset BIOS & CMOS.
Re-install Windows…or go to some Hardware Forum to Fix Windows & Computer.

This is a virus - related forum.

Fix MBR
If you deside to fixmbr then before you contionue I recommend to you to do backup.

Run MBRCheck.exe again in safe mode by double-clicking on it.

[*]Wait until you see the following line: Enter ‘Y’ and hit ENTER for more options, or ‘N’ to exit:
[*]Enter ‘Y’ and then press Enter.
[*]When asked: ‘Enter your choice:’, select option 2 (Restore the MBR of a physical disk with a standard boot code) and press the Enter key.
[*]Now the program will ask: ‘Enter the physical disk number to fix (0-99, -1 to cancel)
[*]Enter 1 and press the Enter key.
[*]The program will show Available MBR codes followed by a list of operating systems as shown below:

Available MBR codes: [ 0] Default (Windows XP) [ 1] Windows XP [ 2] Windows Server 2003 [ 3] Windows Vista [ 4] Windows 2008 [ 5] Windows 7 [-1] Cancel Please select the MBR code to write to this drive:

[*]Please select your version of Windows from the list and enter the corresponding number and then press Enter.
( Enter 0 for DefaultMBR or 1 for Windows XP MBR )
[*]When prompted for confirmation: “Do you want to fix the MBR code?”. Type the full word Yes (not Y or the fix will not work) and press Enter.
[*]Left-click on the title bar (where program name and path is written).
[*]From the menu chose EditSelect All.
[*]Press the Enter key to copy selected text.
[*]Open Notepad, paste that text into it and save to your desktop as MBRCheck.txt.
[*]When complete, you should see Done! Press ENTER to exit…. Press Enter on the keyboard.
[*]Reboot your computer to complete the fix and copy/paste MBRCheck.txt in your next reply.
[*]If your computer does not restart on its own, please restart it manually.

Important Note: The Master Boot Record contains the Partition Table for the hard disk
and a a little executable code for the boot start.
While fixing the Master Boot Record (MBR) is generally safe,
there is a small risk of damaging the MBR,
which may cause the computer to not boot up or it may corrupt a partition.

The following are signs of a damaged MBR:

[]Invalid Partition Table
[
]Missing Operating System
[*]Error loading operating system

If it is the worst case scenario, and your computer cannot boot, please take note of the following:

Please have your Windows CD available, which will allow recovering the boot code via the Windows Recovery Console in case of any problems or install the XP Recovery Console before proceeding with the above fix. Then, if any problems occur, the links below explain how to use and repair the MBR:
