cleaned my computer completely with malwarebytes antimalware a few days ago, but still got ads in firefox.
so i searched for a solution and found this TDSS program from the fully legit kaspersky website

now its broke my w7
doing windows recovery does nothing
tried doing CHKDSK /r and /f, both had no effect
i tried scanning for viruses in ubuntu 10.10 and got nothing.
everytime i go into safemode/normal mode i get BSOD 0x0000007b

reinstalling is not an option for me
please help me recover my windows 7 from this program
i will be really thankfull

you need to make a clone of that drive before you try anything else. use acronis so you dont lose your data. then try repairing your install using the windows disk

You could try repairing the Master Boot Record (MBR).

Hi, since you have apparently a dual boot, I assume you use Grub2 bootloader?

If so, try to reinstall the GRUB boot loader, which you can do using your live cd as described here

i was wondering, maybe i could get everything back to work if somebody else with windows 7 64 bit uploaded their system32 folder for me
and then replace everything
could this work?

No, that could not work, and is also quite illegal. :whistle:

I explained what you need to do in the link regarding GRUB2.

You would not loose your files, but I am not sure this will be fixed. Since your bootloader is not Windows, it will not be repaired by a Windows upgrade.

Not if you want your Ubuntu partition being accessible. GRUB replaced Windows' MBR.

Since you mention a Startup Repair didn't work, I highly doubt an upgrade will.
