    Unable to re-install Windows 7 after Trojan


    Hi,

    My Sony Vaio i3 came with Windows 7 pre-installed on the system - activation code on a label under the machine, no disks.

    I've now got a fairly serious Trojan wreaking havoc on my system and according to AVG the only way to rid it is to wipe Windows and start again. This doesn't bother me, I have all my essential files backed up and the system was running slow for a while before this anyway. However, for some reason I can't seem to re-install Windows. I have no backup (I know, silly me, please don't point out how stupid this is) so I have no restore point that I can return to.

    When I tried to re-install Windows earlier I was told some of the restore files were missing and the operation would be terminated.

    Any help would be greatly appreciated on this, just so I can blitz everything my system and start from scratch. I have moderate knowledge of computers but nothing amazing.

    Thanks for any help.

    Edit: Just scanned with Avast and the reason the file cannot be cured is because it is read only - the original file has been deleted and replaced with the Trojan.

    Do this to open a command prompt when booting from install dvd
    Command Prompt at Startup (option one)
    Code:
    diskpart
    list disks
    I assume disk 0 is the only one!
    select disk 0
    clean
    exit
    Now disk 0 is totally empty. No virus, even a rootkit survives this.

    Now install win7 clean
    Clean Install Windows 7

    Here you can find the drivers for your system http://esupport.sony.com/US/p/select...pe_group_id=10

    Windows 7 Home Premium SP1-U ISO
    English x64: X17-58997.iso

    Download and burn to DVD. Check if you did it right so try to boot from DVD.

    Sorry but I'm gonna need it slightly more basic.

    I downloaded the last link you gave, extracted the folder X17-58997 to my desktop and burned that whole folder to a blank DVD.

    What do I do now?

    And I really appreciate you taking the time to help me.
