Somehow I have the vundo trojan on my work computer. Please help.

I am running McAfee.

McAfee has the following message on the virus.

McAfee has automatically blocked and removed a Trojan.
About this Trojan
Detected: Vundo.gen.ab (Trojan), Vundo.gen.ab (Trojan), Vundo.gen.ab (Trojan)
Location: C:System Volume Information\_restore {202550A8-7A33-4BCA-9586-051D24DDBF8F}\RP872\A0043467.dll

Trojans appear as legitimate programs but can damage valuable files, disrupt performance, and allow unauthorized access to your computer.
.......
Once I click OK. It pops up again with the same information however this time the A0043467.dll has been changed to A0043468.dll and so on and so on......

Please Help me with this issue. I would greatly appreciate it.

Hello and welcome..Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.35) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Thank you for your help boopme. I greatly appreciate it. Are there any more steps needed or has the virus been removed? After reboot McAfee doesn't detect anything. Just thought I would be sure. I don't like to assume anything....assuming always gets me into trouble haha.

Hello, no good question. These are stubborn and I usually find more doing these next.
Run ATF and SAS:
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 Rerun MBAM 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.
After scan click Remove Selected, Post new scan log and Reboot into normal mode

Please ask any needed questions,post 2 logs and Let us know how the PC is running now.

Most excellent results :thumbsup:
Now you should 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 Users can refer to these links: Create a New Restore Point and Disk Cleanup.
