Vundo!grb virus

Hello,

I've been reading the other threads from people who have been having troubles with the Vundo!grb nastiness, and it seems like I am having the same problems. My McAfee antivirus keeps detecting it and "deleting" it and then I get random popups on my internet explorer.

The McAfee says the thing is coming from C:\WINDOWS\system32\amikujoj.tmp or C:\WINDOWS\system32\itojuhin.tmp.

I'm not sure what kind of information you need, so just to be on the safe side I copy and pasted the log from the VirusScan On-Access that has been detecting the virus.

Here is today's log:

Please download Malwarebytes Anti-Malware (v1.34) 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
• Exit MBAM when done.

Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with disinfection. 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. Temporarily disable such programs or permit them to allow the changes. Click this link to see a list of programs that should be disabled.

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it.

• Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
• Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
• If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
• Right-click on mbam.exe and rename it to myscan.
• Change the .exe extension in the same way as noted above.
• Double-click on myscan.scr to run.

Oh good! I did this earlier today, and I think everything is going well so far. I haven't run across any problems.

I did take action though, and delete them like you instructed above. Is this the log you were talking about?

Thank you so much!

Your MBAM log shows "No action taken". This usually occurs if you forget to click "Remove Selected" and instead just click "Save Logfile".
Just to make sure everything was removed, rescan again (Quick Scan) in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. After performing a new scan, click the Logs tab and copy/paste the contents of the new report in your next reply.

It looks like everything is cleaned. Here is the log of the scan I just ran:

You're welcome.

How is your computer running now? Are there any more reports/signs of infection?

So far it has been running fine. No signs of anything lurking as far as I can tell! The only thing that has been weird is my computer randomly switched to army time without me telling it to do so... but that doesn't seem really virus-y.

To change your time, go to Start > Control Panel and double-click Date, Time, Language and Regional Options.
Note: Depending on your settings (classic view) it may show as Regional and Language Options.
In the Regional Options tab, under Standards and formats click the Customize... button.
Click the Time tab, and then click the down arrow next to the Time format box.
Select: h:mm:ss tt
Click Apply or Ok twice to exit out.

Or click on Start > Help and Support Center and in the Search box type: change time display
Press Enter or click the green arrow.
Under Suggested Topics click > Pick a task, click on "Change the way your computer displays the time" and follow the instructions provided.
If there are no more problems or signs of infection, 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 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.

Wow, thanks! You are incredibly helpful!

You're welcome.

Tips to protect yourself against malware and reduce the potential for re-infection:

• Simple and easy ways to keep your computer safe and secure on the Internet.
• Your Guide To Staying Safe Online.
• Hardening Windows Security - Part 1 & Part 2.
• Configuring Internet Explorer for Practical Security and Privacy - How to Secure Your Web Browser.
• Use Task Manager to close pop-up messages to safely exit malware attacks.

• Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

• Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:

• USB-Based Malware Attacks.
• When is AUTORUN.INF really an AUTORUN.INF?.
• Please disable Autorun asap!.

If using Windows Vista, please refer to:

• Disable AutoPlay in Windows Vista.
• Preventing AutoPlay attacks with Vista's AutoPlay options panel.

I also had a Vundo!grb problem and followed your awesome steo by step instructions. I have rebooted my pc and now it is telling me that my automatic updates are turned off. Is this normal? Should I try turning the updates back on?
