First post ..... I hope someone here will be kind enough to help.

I'm using XP-Pro SP3 32-bit and been battling a collection of rootkits (UnReal, AFX2005, FU-Rootkit, TDL4.1) I've have cleanup some, but not all and am now stuck with some hidden files and folders. I've used Panda Anti-Rookit and RookKitRevealer which both show a rootkit in a protected folder posing as a fake HotFix UnInstaller as follows:

The folder cannot be accessed. I have full permissions on all files and folders, except the above folder. I've tried removing it from the command line, with the explorer process off, and also from safe mode.

I've done some of the recommended prep-before-posting and have DDS, GMER, SecurityCheck and MiniToolBox logs at hand.

How do I get rid of this?

Thank you in advance.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic422860.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY 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 make another reply until it has been responded to by a member of the MRT 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 MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.

To avoid confusion, I am closing this topic. Good luck with your log.
