Ran into a new Vista rootkit today that took me by surprise as it replaced volsnap.sys with a hacked version (details tab was entirely empty). Never seen driver hacks like this on Vista/Win7, just XP. This hacked file was not detected by Combofix/Rkill. It was detected by Norton Power Eraser but it could not be fixed. I have the fake volsnap.sys on my USB memory stick that I can upload somewhere if someone wants to take a look at it. The main purpose of this file seemed to be browser redirections as thats how I noticed something was still wrong with the system.

Hello you can submit that file here..
http://www.bleepingcomputer.com/submit-malware.php


I think we can cure this also

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.
