Kaspersky can't delete virus "Rootkit.Win32.TDSS.a"

Posted on 2009-05-15

Hey Guys:

Kaspersky goes thru a special scan for this and then automatically reboots.  But it can't seem to remove it.  It says it's in system memory.  I tried to run system restore and it won't let me.  It seems to know what to stop so you cant get rid of it.  I tried Trend-Micro and Panda online scans to no avail.  I think maybe the only thing I can do is run Hijack this and post the output.  If you have any other ideas that would be great.

Use Combofix or MalwareBytes or both.

You need to rename the tools before saving to your desktop, rename it before actually downloading the file.

Please download ComboFix by sUBs:

You must download it to and run it from your Desktop
Now STOP all your monitoring programs (Antivirus/Antispyware, Guards and Shields) as they could easily interfere with ComboFix.
Double click combofix.exe & follow the prompts.
When finished, it will produce a log. Please save that log and attach it in your next reply by pasting it in the "Code Snippet" or "Attach File" window.
Re-enable all the programs that were disabled during the running of ComboFix..

Do not mouse-click combofix's window while it is running. That may cause it to stall.
CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

If needed, here's the Combofix tutorial which includes the installation of the Recovery Console:

You can also chck if any TDSSserv driver is listed and disable it.
Go to the Control Panel.
Select System -> Hardware -> Device Manager.
Select View from the Menu, then "Show hidden Devices".
Expand "Non Plug and Play Drivers". ,
Right click on the TDSSserv.sys driver and select Properties, Stop and Disable it.
You will be asked to restart the computer, Select No.

Also disable seneka  or gao##### drivers if found.

Have you tried to scan a full scan with KAspersky in safe mode first ?

Hey guys:

I will try all these things later on tonight.  I have a busy Sat. planned.  I will post back then.  


I did try Kaspersky in safe mode.  In safe mode it passes right by it so I think it must be something that is turned on and becomes visible at startup.  When I start the scan, it snags it within 2 seconds and wants to run a special scan routine, delete and then re-boot the system.  When it re-boots and I run the scan again, its back and wants to repeat the routine over and over again.  It does offer the "skip" option, but, that not really helpful!!!

Thanks for the input and I post back later.

I found the same rootkit on a computer in my organization about a month ago.  The only thing I found that would remove it was UnhackMe available at  It's not free but you can use it one time to remove the rootkit and uninstall the software later.  I would scan your computer with Unhack Me and it will ask you to reboot your computer.  Reboot your computer and it will scan your system on startup.  It will notify you of any suspicious programs.  I used Panda on this computer before hand and Panda would only scan about 1000 files on the system and report it as "clean".  I knew something wasn't right because (a) there are more than 1000 files on the computer and (b) the scan finished in about a minute.  Once UnhackMe removed the rootkit, follow up with a Panda scan.  I would also recomment downloading MalwareBytes and running a scan.  A layered approach is always a good solution.

Glad to know it's been resolved.
Since you didn't show us the Cf log, you might like to wait for a day or 2 before uninstalling combofix ,as its uninstallation will also remove the backup.

To uninstall Combofix:
Go to Start > Run and 'copy and paste' next command in the field:

ComboFix /u

The above process will remove Combofix and its files, delete the created backup and reset System Restore.

Hi, thanks for all the help you have given me. I have had that virus on my computer & have been trying to get rid of it to no avail. The combo fix has done the trick. I have attatched the Cf log if anyone wants to look at it. Do I have to do anything else?

Hi Tammy:

I'm glad I was able to help you out. That was a tough one to get rid of but ComboFix did it with ease. Who knows what other viruses there are going to come up with next. I have also added the UnhackMe program to my computer. It also does a nice job. If someone checks back with this post they may take a look at your log file. You could post it over at ******** I am sure you will get a reply to it there.

Take care

Hello all, I have this exact same problem and I ran combofix and when i restarted Kaspersky, it all came up again. Same as before.

Did I miss something?

Once a system has been compromised by a rootkit, it is impossible to be 100% certain that the system is clean. A rootkit usually modifies parts of the OS to hide itself. How can you trust the OS after that?
Kaspersky and all of the others can only clean what they know about. There could be an unknown rootkit or variant still on your system.

I recommend you backup just the data from the system, reformat the hard drive, and do a clean installation of the OS from a known good DVD.

That's the only way to be sure the system is clean.
