Thank you so much for responding. I really appreciate Bleeping Computer volunteers and the site itself, impressive the work you do, also the information and tutorials.

I had two computers with the TDSS virus, a Dell laptop and a desktop. While I was waiting for a reply, I kept trying and managed to get the virus off the Dell laptop by reading a lot in the forums and finding out about the TDSS killer by Kapersky. I ran it. Unfortunately running the TDSS killer not only removed the virus it also corrupted the boot sector. Then the laptop wouldn't boot. My heart sank. It gave me a "NTLDR is missing error." It is a Vista machine which I learned doesn't even have a file called NTLDR.

Anyway I managed to use a Vista boot disk and started the Repair Console and did bootrec.exe /FixMbr. That didn't work, so I went back into the Repair Console and did /FixBoot and then did a chkdsk for good measure and at the end of all that it booted, and NO MORE TDSS, or a hijacked browser or anything!!! That was really satisfying to get that virus off...

The desktop is a different matter. I ran the TDSS killer on it too, several times, and unlike the laptop, it booted afterward, but the virus just keeps coming back.

I'll attach the Combofix log as you told me to. It's from the desktop which is still infected.

I'll attach the TDSS log too.

Oops, I forgot to do the DDS log. I'll do that in the morning. Hope that's okay. Thanks again.

I'm sorry. I didn't think anyone was going to answer and finally just reformatted the desktop. I just looked now and saw you responded. Next time I'll wait longer. Thank you so much for replying. I really like Bleeping Computer. Thanks again.
