I am working on a computer for a friend that was severely infected with Trojan downloaders, Backdoor bots, root kits, etc., etc. I was able to use a bootable disc in order to clean the hard drive enough in order to boot the OS, so that I could use Malwarebytes, SuperAntiSpyware and three different online scanners to clean the PC enough to keep it running. The computer had well over 150 various viruses. I am now getting an infection in System Volume Information\_Restore(D5FFFA500B1B)\smss.exe, and System Volume Information\_Restore(D5FFFA500B1B)\ svchost.exe. I have used File assasin to remove these to executables, but everytime I reboot the machine, they come back. Trojan.Agent/Gen-FakeAlert, and Trojan.Dropper/SVCHost-Fake. If I connect to the Internet on the machine many more viruses start to be downloaded. I need help and guidance. Thanks in advance. I should mention the OS is XP Home edition. I removed an outdated (2006) McAfee, and installed Security Essentials, Malwarbytes, and SuperAntiSpyware.

Edit: Moved topic from XP to the more appropriate forum. ~ Animal

Hello let's do this..

We will Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.




Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

You needed a reboot after that one..

Lets do these now and see if anything shows. I know you have run some but we need the latest logs.

Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Now an online with ESET
Please perform a scan with Eset Online Antiivirus Scanner.
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista users need to run Internet Explorer as Administrator. Right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select Run as Administrator from the context menu.
  • Click the green ESET Online Scanner button.
  • Read the End User License Agreement and check the box: YES, I accept the Terms of Use.
  • Click on the Start button next to it.
  • You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then click Insall ActiveX component.
  • A new window will appear asking "Do you want to install this software?"".
  • Answer Yes to download and install the ActiveX controls that allows the scan to run.
  • Click Start.
  • Check Remove found threats and Scan potentially unwanted applications.
  • Click Scan to start. (please be patient as the scan could take some time to complete)
  • If offered the option to get information or buy software. Just close the window.
  • When the scan has finished, a log.txt file will be created and automatically saved in the C:\Program Files\ESET\ESET Online Scanner\log.txt
    folder.
  • Click Posted Image > Run..., then copy and paste this command into the open box: C:\Program Files\EsetOnlineScanner\log.txt
  • The scan results will open in Notepad. Copy and paste the contents of log.txt in your next reply.
Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Unfortunately, I am unable to boot into Safe mode. The system is hanging at Mup.sys, and then giving a fatal error. I did, however follow the steps in Normal boot mode and have posted the logs here:

  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.

Thanks! I was able to repair Safe mode using the method you suggested. I followed the above steps again in safe mode. After rebooting I ran another quick scan with SuperAntiSpyware and it is still showing these infections:
Trojan.Dropper/SVCHost-Fake
C:\SYSTEM VOLUME INFORMATION\_RESTORE{D5FFFA500B1B}\SVCHOST.EXE
C:\SYSTEM VOLUME INFORMATION\_RESTORE{D5FFFA500B1B}\SVCHOST.EXE

Trojan.Agent/Gen-FakeAlert
C:\SYSTEM VOLUME INFORMATION\_RESTORE{D5FFFA500B1B}\SMSS.EXE
C:\SYSTEM VOLUME INFORMATION\_RESTORE{D5FFFA500B1B}\SMSS.EXE

Microsoft Security Essentials popped up during the scan with an infection in C:\SYSTEM VOLUME INFORMATION\_RESTORE{D5FFFA500B1B}\SMSS.EXE and informs me that it is a Trojan Downloader: Win32/Unruy.D.

Here is the log from the SAS in safe mode, followed by the quick scan log in normal boot mode:

Heelo we need a DDS log and a new topic. Mention in it that you've created a new restore point yet these files still remain.

We need a deeper look. Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.
How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/319178/infected-with-trojandroppersvchost-faketrojanagentgen-fakealert-trojan-downloader-win32unruyd/ 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.

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

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
