Hi everyone,

I'm new to this site and this is my first post, so I hope I'm using it the way you all intended :thumbsup: !! I seem to have a virus that's called worm.win32.netbooster. I've googled it and according to what I've read, it's trying to get me to download a "fix" that's really a worse virus.

I have an old VAIO laptop (PCG-K17), I'm running Windows XP with Service Pack 2. My Internet Explorer is version 7.0.5730.13IS. I've had no new applications installed and no other changes to my pc, but apparently a random web surfing session and a mistaken download has left me with this virus.

Some of the symptons include:

1) A message that says "VIRUS ALERT!" in the lower right side of my screen by the clock
2) I cannot access my control panel, as the only option now listed under START > SETTINGS is "Taskbar and Start Menu"
3) Several consistent popups that tell me that my computer is infected with a virus. Some are vague but one in particular names worm.win32.netbooster as the culprit
4) Internet Explorer randomly opens itself and takes me to various places to download "fixes"
5) There are lots of new buttons in my Internet Explorer that I cannot delete including "Remove Popups" "Scan Spyware" "Security Test" and "Spam Protection"
6) The virus has changed my IE homepage to: http://softwarereferral.com/jump.php?wmid=...6Ojg5&lid=2
6) My pc is running VERY slowly, as it appears the virus is consuming most of my pc resources

I found this post on bleepingcomputer.com about worm.win32.netbooster: http://www.bleepingcomputer.com/forums/t/140864/wormwin32netbooster/

I followed some of the instructions, but I realized I should probably re-post since my problem could be slightly dfferent.

So far what I have done is run Lavasoft's Ad-Adware, which found several crtical objects and removed them, but that did nothing to resolve my issue. I also ran CCleaner, which removed some things (as it always does) but again that did nothing to really help. I generally use Ad-Aware, Spybot, and CCleaner every month or so to keep my pc clean, and I defrag every so often. In the past I used Norton Anti-virus, but I found it did next to nothing but consume PC resources, so I got rid of it about a year ago. I keep my installed applications to a minimum so this rather old laptop can run more smoothly (only 512 mb of RAM!!!)

Following the above post, I downloaded SmitFraudFix to my desktop, though I haven't used it yet. I then downloaded AVG and ran it while in safe mode, and I watched it pick up about a dozen files and quarantine them. When I rebooted, I was able to access my Control Panel, and the "VIRUS ALERT!" message by my clock had disappeared. But slowly all the symptoms returned, I can only assume that parts of the virus are still on my pc and they just re-downloaded whatever AVG removed.

Before I do anything else figured I should ask for help. The AVG I downloaded seems to be a newer version than the one mentioned above (I got version 8.0) so some of the instructions I could not follow exactly.

Any help would be greatly appreciated, and I apologize if I overlooked a previous post that has covered this. If I have, a link to that post would be most helpful.

Kind regards,

Rob T.

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.

Hey quietman!!

Thanks so much for the fast reply!! Here's how it went down, unfortunately not as smoothly as I'd hoped:

I did as you instructed, and on the first scan it located 90 Objects Infected. I clicked Remove Selected and after a few seconds I received pop up message titled "Malarebytes' Anti Malware" and the message read "Regedit has been disabled and will affect the quarantining process. Malwarebytes' Anti-Malware will now enable Regedit." There was an OK button so I clicked OK - I didn't have much choice lol

The program's status bar continued to slowly process the 90 objects, and went all the way to 100% with the final status bar reading "Verifying removal" or something to that effect. I noticed a few of the items in the list under the "Action Taken" column got changed from "No Action Taken" to "Delete on reboot". But then the program froze!! The title bar showed a "(Not Responding)" in the title bar. I don't know for sure, but I have seen this happen before with other spyware removal programs when there are so many things to be removed that the program just crashes.

So I left it for a while to see if it would continue, but it didn't, so I eventually had to close it. I immediately reopened the program and checked the tabs and saw only 64 of the 90 items were listed there in quarantine. So I immediately disabled my internet and rebooted the computer. I disabled the internet because 1) I knew the program had the latest update installed, and so shoudn't need access to the internet, and 2) per my original post, when I had scanned with AVG, I noticed many symptoms went away but then slowly returned, which I assume means the remaning virus re-downloaded what I'd removed.

After the reboot, at a glance I could see
1) the "Virus Alert!" message next to my pc clock was gone
2) the icons from my desktop were gone (a symptom I forgot to mention in my original post)
3) I had access to my Control Panel again, and
4) I had access to my Task Manager again

I then opened the program again and checked the quarantine tab and nothing had changed (it still read only 64 items), so I ran a second quick scan. That scan completed successfully (rather quickly too) showing 16 Objects Infected. I did as before and clicked Remove Selected and within 10 seconds the Notepad file appeared as you said it would! However, it only listed the items from the second scan!

Here is that file:

C:\WINDOWS\system32\GgQWayay.ini2 (Trojan.Vundo) -> Quarantined and deleted successfully.
C:\WINDOWS\system32\nnnnNDwx.dll (Trojan.BHO) -> Quarantined and deleted successfully.


Now when I look in the quarantine tab, I see 78 objects in total... which is less than the original 90 found by the first scan (and doesn't even add up right, 64 from the first scan and 16 from the second should be 80). And I only see one log file listed in the Log tab, maybe there was another there before I ran the second scan!! Dammit!!

So all I can locate is the log file from the second scan. Seems I kind of messed this up a bit... The 78 objects are still in quarantine, I haven't deleted them yet. There are a number of them listed as "Trojan.FakeAlert" and "Rogue.Vendor" and "Trojan.Vundo" and "Rogue.VistaAntiVirus2008".

So that's what I got at the moment. My pc is running MUCH more smoothly now, and I honestly don't see any symptoms that I did before, though I'm still weary about logging into any site that needs a password (email, online banking, etc) in case there is still keylogging software on my pc.

What do you suggest I do next?

Thanks so much for your help!!! I sincerely appreciate it!!

Kind regards,

Rob T.

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 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".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
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.
