I've been at this problem for a week.

A little background: I'm a tech with years of experience removing junk from computers. Right now my own machine is busted, so for the time being I've been using my girlfriend's box to access the internet.

Well, she hasn't been listening to me and had a few nasties loaded on her machine, the worst being some hellish Virtumonde variant. No matter which utility I use, taking out Virtumonde's registry entries also takes down the SOFTWARE registry hive. I've attempted this using AdAware, Spybot Search and Destroy, TrojanRemover, Windows Live Onecare online scanner, VirtumondeBeGone (Or maybe it was VundoBeGone, can't recall), and VundoFix.

After hitting "last good configuration" a few times, normally I can get the system back up, but this also restores Virtumonde's registry entries.

This last attempt, no option after hitting F8 prevents the stop error.

Reformatting is not an option, neither is a recovery install (no disk, and the built-in recovery partition of her computer is woefully outdated [it would take longer to reinstall and update than it would to figure this problem out).

So far my shiny new Ultimate Boot Disk for windows fails to actually run on that machine (inexplicably reboots), so that's one option I'm now forced out of. I haven't been able to try using a USB version yet - the machine I'm writing this post from is an 800Mhz Celeron box with USB 1.1 ports and DMA controllers that only go up to level 2(!).

I'm going to try booting from Knoppix and fiddling with some of the system restore snapshots to see if I can at least get the SOFTWARE hive functioning again. Or, I would if the NTFS file system could be accessed by it (my Knoppix build requires a clean windows shutdown in order to access NTFS volumes).

Oh, did I mention that I've been at this for a solid week? I've been here at her house, unable to even snuggle with my cats...:thumbsup: Please help me. :flowers:

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the HJT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your log in the thread titled "Post in this thread when you haven't received an answer in five days.".

It would have been wonderful if you had actually read my post.

Windows cannot boot, ergo there is no way to post a HT log. I need help figuring out how to remove this without hosing the registry, not help with basic removal techniques. I've been through all of them.

Solution Found:

The repeated access to the registry by more recent variants of Vundo/Virtumonde seem to cause the registry to accumulate bad clusters. Including this machine, I have encountered this two times already. Some serious research via Google netted only one topic on an obscure forum with a similar issue - the user kept regular backups and found no trouble with reformatting his machine. Chances are this isn't widely heard of because any users encountering this specific issue would take it to a repair shop, repair guy would get frustrated and push to wipe the machine/reinstall anyway.

To solve the problem I simply had to run chkdsk /r, forcing chkdsk to look specifically at the registry hives. I would suggest posting this somewhere for all users to see in case they come across this themselves, which I have a feeling they will in increasing numbers.

I apologize for getting snippy with you, Mark. I've been toiling at this for a solid week until 2:00am or later each night I've been at this, so cranky, yeah.

Pleas kill this thread, thanks.
