Hi. I'm working on a PC for a friend. She had it in storage for a while, so she asked me to look it over.
I know this PC is still infected. I've run several programs to get rid of malware, but Spybot, for example, can't remove the items even after reboot.

There seems to be some security restrictions also. I can't access some registry keys that Spybot has indicated are infected.

I have attached the DDS.txt, Attach.zip & GMER log file for review. (I had to zip the ark.txt to get it to attach. It was to big).
I have also attached the last Spybot log with the items it is unable to remove.
Any help is appreciated.

Thanks for your assistance.
I am still experiencing problems with this PC.
Win XP Pro SP2, 32-bit.

There are registry keys I cannot delete and Spybot is telling me that it can't remove them either.

I have run the OTL program.
I checked the 'All Users' box. The other thing I changed was 'All' under file age because I think it has been over a year since this PC has been infected. This made the OTL file very large.

I had to break up the OTL file and zip the resulting files, too.

If it is too much to look through, I can do the scan again with the default '30 days' checked.

You will see that there are a lot of AntiVirus/AntiMalware programs installed. That is because I have tried different ones to see if any could get rid of some of this infection. I do not plan to leave them all installed.

I await your instructions.

Hi,

what makes you think you are still infected? What are those registry entries you can't delete?

I have looked through some of the info (the one that's a year old) as the XP files date back to 2001, I did not review all of them.

Could you please run a scan with Rootkit Unhooker next:
Please download Rootkit Unhooker from one of the following links and save it to your desktop. Link 1 (.exe file) Link 2 (zipped file) Link 3 (.rar file) In order to use this tool if you downloaded from either of the second two links, you will need to extract the RKUnhookerLE.exe file using a program capable of extracing ZIP and RAR compressed files. If you don't have an extraction program, you can downlaod, install and use the free 7-zip utility.
  • Double-click on RKUnhookerLE.exe to start the program. Vista/Windows 7 users right-click and select Run As Administrator.
  • Click the Report tab, then click Scan.
  • Check Drivers, Stealth, and uncheck the rest.
  • Click OK.
  • Wait until it's finished and then go to File > Save Report.
  • Save the report to your Desktop.
  • Copy and paste the contents of the report into your next reply.
-- Note: You may get this warning...just ignore it, click OK and continue: "Rootkit Unhooker has detected a parasite inside itself! It is recommended to remove parasite, okay?".

Hi Myrti,
I think the PC is infected because the following programs say there are infections (Spybot, SuperAntiSpyware, MalwareBytes) and the program cannot delete the items. Even when I choose to reboot and run the program on startup, I cannot remove the infections.

Some of the registry keys that I cannot remove are in the text file titled 'Checks....' in my original post for this topic.
I am able to remove them if I go through the painful process of assigning permissions to the Administrator account to each subkey and then I can delete them.


I am unable to run RKUnhook. Even in Safe Mode, it tells me that there was an error loading the driver.

Please tell me what the next step is.
Thanks.

Hi,

can you show me a log from Malwarebytes with the items it can not delete?

It's nothing unusual for a registry item to have no "delete" permission for the administrator, that per se is not necessarily something to worry about. You said you had to change permissions and delete the entries. Did you do that, did the entries come back?

RkU will only run in normal mode, please make sure al security applications are disabled before you run it.

Hi,
I only deleted a few registry keys using the 'painful' process. They have not returned.
Attached is a MalWareBytes log.

Still no luck with RKU. I'm in normal mode, logged in as Administrator and disabled all security. I get an unhandled exception error.

Hi,

can you do a new scan now? Are those entries still present? (Please make sure to update the program before running the scan)

I am still unable to use RKU. It won't open, therefore I cannot do any update or scan.

Hi,

please run a scan with Gmer again in that case:
Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and re-enable all active protection when done.
-- If you encounter any problems, try running GMER in Safe Mode.

Please post the logs into your reply instead of attaching them.

Hi Myrti,
I ran another scan with MalwareBytes. It returned 0 infected files.
However, when I run Spybot, I still have 21 items that I cannot delete. The program tells me that there 21 items that cannot be removed. Would you like to run the program again at startup?
I choose yes and let it run on startup -- it finds the 21 items, but still cannot delete them.
Should I just re-assign permissions to these registry keys and delete them manually?
Some of the infections it is seeing are 'Zango', 'SpyAxe', '180Solutions'.
The registry keys are in the 'Checks...txt' file attached to the first post for this topic.

Hi,

can you run a scan during normal run and let me know if the files get detected as well.
