Rootkit in Windows 7... (Vitro Virus! Come in if you need help.)

Well, that's the rub. I have a rootkit but can't fix it because ComboFix doesn't run in Windows 7 yet. Unless i'm wrong...which is what I'm hoping.
Otherwise, you guys have any ideas of what I can do? I even fully reinstalled Windows 7 and it's STILL there. I get popups every 15 minutes or so for "http://85.114.141.207/meds/" with a little diologue box telling me to click "Yes."
It's notihng too harmful but its SUPER annoying. Ugh.
Hijackthis, Spybot, Anti-Malware, nothing helps.

I have a vague recollection of reading something about a virus that infected your bios. That would be scary indeed.
Though DE25's problem sort of reminds me of that non-damaging "virus" that someone built into the gcc compiler. Even if you had a clean copy of the compiler source code, the compiler virus would simply insert itself into the newly compiled compiler.

I would do a bare Windows install, run updates and then install apps one by one. Use each app for a day or two until you get the popups, then you will have a likely culprit. You could also have an infected network device or bad DNS server. You could (should) switch to opendns.com. Please post results or more info if you make progress.
You could also use process explorer to get some more info about the popup, such as its parent process. This could lead you to the location of the malware.
Thanks.
Right now I'm running Windows 7 barebones - aside from basic drivers, Firefox, Thunderbird, and Spybot, everything is off. I'm re-downloading a fresh copy of my 64-bit Windows 7 (7100) build for installation as we speak.
Sure it could. Rootkit could infect specific sectors on the hard disk each time, and the BIOS virus could be programmed to do nothing more than flag a few critical bytes of data as files rather than blank space. You could fit a virus that small into BIOS. Hell, the rootkit could even infect the MBR, pointing it at the critical spots. Unless you do the reinstall in such a manner that it forces the MBR to overwrite, you're still screwed each time you re-install.
CUZ THERE'S SOMETHING IN THE MIDDLE AND IT'S GIVING ME A RASH

Hopefully I'll find success tonight!

Thank god I just keep my main data off on a separate hard drive.
EDIT:
Still at 0% and over 400 Win32:Vitro infections...
Anyone who's read about Virut knows what a fucking son of a bitch that virus is.
I would just skip the scan and reinstall now.
[edit]though, if this thread is any indication, Vitro has a tendency to return even after a reformat. That's pretty worrying.
Running on Windows XP, have tried a lot to, but nothing worked out for me.
I do have a lot of weird windows taskmanager processes running, but when I kill them they keep coming back, even if I delete them in the C:/windows maps.
2 days ago the pop-up was an other site : http://www.guarddog2009.com/xxx/
Which was showing porn pictures by then, but now it changed to the same med thing., I'm glad that it changed to med-pills instead of porn, but it still sucks.
Pop-ups are also then when i'm not using the pc, and not even having a browser opened, so the virus opens browser itself. And when i'm playing a game or what-so-ever, the game mimimalizes to show the pop-up, which is also quite annoying.
It looks like my pc is having multiple virusses, but all repairing eachother. Different virusscanners do not solve the problem, neither does HiJackThis..
Also desperate for a solution.
EDIT : "Format / Re-installing isn't a real option for me, so I need to get this fixed
I'm far, far from a malware expert. But would booting off of a Linux CD and copying non-executable data files fix your problem and let you reinstall?
Stuff like this would make me think of this as the easiest way.
(Please do not gift. My game bank is already full.)
It's also not out of the question that someone could write a normal, non-BIOS virus that (in addition to its other functions) would detect when you downloaded a Windows install disc image and automatically infect it. I've never heard of it happening, but it's certainly easily possible. This is why you don't use the infected computer to download a new copy of Windows.
If that hard drive has ever been connected to the infected computer, that might be the problem. I don't know Vitro but if it's anything like Virut, it infects any sort of removable media attached to an infected computer via a autorun.ini file. Since you said you already formatted and reinstalled, I bet it just reinfected you when you attached some sort of removable media it had infected previously. You should probably boot with a LiveCD and format any external hard drives, USB drives, etc. that have touched the computer. While backing up your important files keep in mind that any .exe, .html, or .dll files are probably infected and can't be allowed to survive. Then format your main drive and reinstall. Don't attach any clean external media to an infected computer or vice versa while windows is running. So long as you format everything from inside a LiveCD environment and don't back up any of the sorts of files it attaches to, you should be okay.
But sweet zombie christ on a pogo-stick, this Vitro bug looks nasty. How the hell can it infect after reinstallation? And how the heck does it infect to begin with?
Still it's pretty scary to see peoples reaction going from "After looking at your log files these are the 15 steps you need to clear your computer." that you normally see to "Fuck it. Nuking from orbit is the only way to be sure."

edit: what I mean, do you have to run an exe, has it other vectors?
I'm curious about this as well. Forum threads about the `tubes seem to indicate that online movie watching (i.e. sites promising cinema run movies, not YouTube) can lead to infection through the old 'You need a Codec!' trick, but as Vitro evolves, it might need less and less user input. Was there any indicatin of what caused initial infection, DEagle?
Probably easiest to just reformat. If it's just a USB drive it shouldn't be too difficult to copy off everything that's not an .exe, format, and put it back. I wouldn't let it touch a Windows computer even with autorun turned off, there's no such thing as being too careful with Virut and its derivatives. Normally you'd want to boot up a Ubuntu LiveCD and format from there, but a Macbook should work fine too. Just make sure you don't miss some piece of media, remember that it infects stuff like the SD cards in cameras or those dumb electronic photo frames that you might not automatically think of.
IE on Vista & Win7 has three layers of protection that keep things like this from installing. First, ActiveX controls have not be allowed to auto-run since IE6. Second is protected mode, this is a sandbox mode that keeps web items from installing/running in your system. Third is UAC, that works with protected mode so any program from the web has to get your permission to install or run.
UAC has already been recording at being 100% effective at blocking root kits. This thing slips in off flash media and installs of codecs. This is not an IE issue, though you should always keep IE up to date whether you use it or not.

it is extremely annoying. AVG has picked up hundreds of nasties over several runs and I am watching these forums to see if there is any way out apart from formatting. I have had several external devices attached and don't really want to format all of them if i can help it as it is just too much effort to replace all of it.
And I actually like UAC and the control it gives me, and never can understand people bitching
But I think I'm in minority :P
On your new install, make a secondary admin account and change your personal account to limited. Use run as or a separate instance of explorer to perform admin tasks.
Disable autorun to prevent infected media from auto-running and spreading themselves.

You should be fine with only clearing out all .exe, .dll, and .html files on the external drives, rather than a full reformat. There could be an issue if you ever boot from those drives though.
My uninformed impression is that the biggest problem is some auto-exec . file. I'd go with pull all known non-execs off and nuke.

For starters you need to try a different anti-virus, AVG has limited ability at removing viruses. Download the free trial of NOD32. You could also give Malwarebytes a try, it's probably the best anti-malware program.
Could you elaborate? This is the first time I have heard this, any other gripe against AVG has been it's simplistic UI and its penchant to mark Windows system files as viruses when they aren't.
I've used this to take completely ruined PCs to fully usable. Also make sure to keep a good real-time scanner going and DISABLE AUTORUN. Lately autorun on USB drives has been spreading viruses like crazy in offices and stuff.
Edit: I recommend Avast! or Avira for free anti-virus. They seem to be the top dogs in ratings. They're both fast, too.
Edit again: Here are some basic instructions for TRK virus scanning. Keep in mind I only boot with SSH so I use Putty to connect remotely, but this should work on the computer itself when you are at the command line.
From this page - the command is "virusscan" and you use the argument "-a" with one of the scanners. So to scan with AVG you would type "virusscan -a avg" and press enter, then let it run. It may ask Y/N questions about downloading the updated virus definitions. Then say you want to run bit-defender you would use "virusscan -a bde". Typing just "virusscan -help" and pressing enter will show you a quick help and list the different virus scanners available (I think it has more than the web page lists).

I didn't format or reinstalled anything, just killed lots of processes and run lots of anti-malware/virusscans, and did some stuff on my own. LOTS of GOOGLING
but when it's fully away for the next 24 hours to, I will try to figure out what I exactly did
I love Avast and Nod32.
