I have to apologize for posting this in your topic, but I can't seem to create a new topic, for some reason.

I have a problem, and it may be Vundo related. I've been getting a few Vundo alerts recently. Ones which involve my computer trying to connect to a computer in Germany. However, I haven't experienced any problems. Until, of course, about ten minutes ago. The taskbar started flashing on and off for little bits at a time. Something was killing Explorer, because everyime it popped back up, the system tray was reloading. It got to a certain number of icons, and BAM, dead again. I though it was rather odd, naturally. It soon setteled on staying on, with no system tray and not letting me open anything on the stary menu or any shortcuts. So, I killed Explorer fromt he Task Manage. Now, lucky me, I have RK Launcher, a dock from which I can run things, such as Explorer. So, I used that. Now we're back to endless flashing, but at least I can click on things. However, it never lasts long enough for me to do, well, anything. Opening anything like My Documents just makes it flash off again, taking that with it. So, I killed it once again, and used RK Launcher to open Opera. I had tried to run a Vundo tool from Symantec earlier, but it gave nothing. Also, after that the alerts stopped. This all seems like malware related behavior, but I haven't seen anything Vundo-related, like "Click here to scan for spyware" pop up yet. Also, a couple root kits have been blocked by Norton. Now, my computer ran fine all day, and ran fine for a half hour before this. I haven't done anything in that time that would aggrevate malware or anything out of the ordinary. Also, it might be good to mention I have a hacked uxtheme.dll, and have for quite some time. I have not installed any new themes within months, however, so I doubt that's it. What I need to know is:
How can I cause Explorer to remain stable?
Would a restart help? I'm afraid to because I'm not sure if I'll lose control of it completely.
Is there any way I can get Norton to run, even without Explorer?
Also, does this strike you as Vundo, another malware, or something else entirely?

Again, I appologize for commandeering your topic, but I can't get a new topic to work and I'm fairly freaked out right now.

Also, here's a picture of the original log: http://img374.imageshack.us/img374/4133/ss...08185545gg7.jpg
And this is where I first discussed the problem, before it actually became a problem: http://www.zuneboards.com/forums/tech-help...html#post277887
A speedy reply would be immensely good, because I don't know what to do. On a good note, I managed to beat Explorer's kill time in order to run Norton, so now both the tool and a full system scan are running. Is it safe to install another scanner and give it a "second opinion?" Sometimes multiple scanners can pick up each others slack, but I'm not sure if it's wise to install anything while the computer is acting like this. Also, files: is there a way I can access my files and copy them to my external hard drive? I have some pretty important stuff that's not backed up, and I'd like to be able to save it, if possible. Oh, and just so you know, I'm using XP Home.

Hello and welcome. That Vundo tool is a bit dated.
Please run this

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
  • 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. Reagardless 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.

Your MBAM log shows "No action taken". This usually occurs if you forget to click "Remove Selected" and instead just click "Save Logfile". Please review these instructions (scroll down), 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.

These ones without action were removed after reboot. Windows gave me a couple errors when it loaded saying that some of these ones in question were not valid applications. I'm running a full scan right now, but the computer runs fine.

Reboot, rescan again with MBAM (Quick Scan) in normal mode and check all items found for removal. Don't forgot to reboot again afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Also let me know how your computer is running and if there are any more reports/signs of infection.

I ran it again, and it has found nothing. It has not exhbibited any strange behavior since the first scan, even while putting the system under moderate strain. Though, looking at these last two removed objects, I noticed something strange: both were files I got from trusted sources, and both have never done a thing to harm my computer. The first is to edit the number of half-open TCP-IP connections, and the second is a patch for a program that turns text into Zune-screen sized pictures. Is it possible that they were commandeered by the main infection, or is this scan simply being a bit overzealous?

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.
  • 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.
If you suspect false detections on those two files, then report them to Malwarebytes' Anti-Malware Support > False Positives.

Oh, I had already turned off and removed all restore points before running this, as a precaution, and created a new one last night. Thanks for the help, you saved my computer!

You're welcome.

For Tips to protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid gaming sites, underground web pages, pirated software sites, 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 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.
