Hi there, I am a long time lurker on this wonderful site. Usually I can get whatever fix I need by searching previous topics and following the advice on there. However, this Vundo has gotten me and is being so stubborn, I finally have to post a topic of my own asking for help. (I'm aware there are a couple of other Vundo topics going on but I didnt want to hijack other people's threads). The symptoms are: google/yahoo links being redirected, occasional adware popping up. The adware is not as bad as those rogue "antivirus" programs, but still popping up annoyingly.

I've followed some of the advice seen in the other threads; I update and run MBAM regularly anyway, but I also DLed SuperAntiSpyware. I tried to run SAS but the computer suddenly stops dead and reboots during the scan. Running MBAM isnt helping for once, even after the reboot the Vundo is still there. Here is my latest MBAM log, I'll be allowing MBAM to reboot me again after posting this. Thanks!

Hi boopme, thanks for your response

I followed the instructions to the letter, and when I rebooted after running ATF and SAS in safe mode, my computer can't get online, it doesnt seem to see the modem anymore (I'm typing this from my wife's PC, which obviously still works fine. Both PCs are on the same connection. My PC can still see this PC, but cant get online like this one can)

I assumed I did something wrong so I used restore system to go back to right before I started (could get online again then), and carefully did the whole procedure again, unfortunately with the same result, can't get it online anymore. A check under Device Manager shows all of the items under Network Adapter with Yellow exclamation points, and the error message that Windows is unable to find the drivers for this device (code 39)

I can't post the log file from the SAS scan, because I cant get that PC online. Any suggestions before I restore system again?

Hi, ok tried that, still not working.

I edited the previous response with this sentence just as you typed in your response

"A check under Device Manager shows all of the items under Network Adapter with Yellow exclamation points, and the error message that Windows is unable to find the drivers for this device (code 39)"

does that make a difference?

How about these...

For Windows 2K/XP
Please go to Start -> Control Panel, and choose Network Connections. Then right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and left click on properties. Double-click on the Internet Protocol (TCP/IP) item and select the radio button that says Obtain DNS servers automatically. Click OK twice, and restart your computer.

***
Device drivers can be checked or rolled back by going to the Device Manager. Open the Start menu, right-click on Computer menu listing and select Manage. Alternatively, you can go to the Control Panel and select Computer Managment from the Administrative Tools section.

In the computer managment console, there's an option to view the Device Manager. In there, you'll see a tree style view of your computer, and the devices connected to it. Devices that have issues - such as the Code 39 error - will have a special icon - usual a yellow triangle or red stop sign. You can right click on the item that's got problems and select Properties. On the Properties dialog box, there's a tab called Driver - and there's an option to "Roll Back" the drivers for that device - this takes the current driver and removes it and replaces it with a previous version of the driver.

Of course, this only works if there was, at one point, a working driver that was updated or replaced.

Hi boopme, OK I tried those solutions with no luck. I have used system restore again, tried it again, and got the same result. System restore once more, and tried ATF in safe mode, came back and it's OK. So I assume its the SAS that is nerfing my network adapter drivers.

I have tried an update on the drivers, they are current.

After the restore I am back where we started.

Any ideas?

Hi Ok I have never seen SAS do this before,if it did. But Lets' uninstall it thru the control Panel. Add /Remove programs or it's uninstaller in All Programs.

Then try doing a system restore to a date prior to the looss.

Yeah its bizarre. Anyway, done, SAS is gone and system is restored, complete with Vundo. Wish I had a restore point from before this thing hit me.

I still have ATF, spybot S&D, and MBAM on here.

Hi boopme! Ok, I have run MBAM again in full scan. The result was that Internet Explorer was crippled again, and now my system restores dont return it to functionality. I was panicked, but then found that firefox now can connect OK. Curiouser and curiouser! I hardly ever use firefox but thats what I'm using right now to type this. Here is the log from the full MBAM scan:

Hi, Did you Reboot normally after that scan to complete removal? If not do that next. Now did you get AFT and SAS to run? I'd like to use them,then another Quick MBAm...

IF SAS stilll won't run let me know,but run the MBAM again too.
Also Backdoor.Tinxy.. Will steal your persoanal info,financials and password.. Itwill also spread thru a network .Are you on one?


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.

Hi, ok the current state is a mixture of good news and bad news I suppose :thumbsup:

The good news is that my IE and Firefox both are running OK. I am on a small network of just 2 home PCS and the XBox/PS3, and the proxy server box had been checked. When I unchecked it this PC went back to connected normally.

In other good news, the redirects from google/Yahoo links have stopped!

The bad news is that I still cant get SAS to function properly; in normal mode, it goes for about a minute then the whole computer stops and reboots. In safe mode, it completes but after that my browser dont work

Also, there are still a few threats showing in MBAM scans, I've run the scan several times and these same 4 or 5 keep remaining, even after reboot.

In short, progress is being made, hooray and thanks! But I still wonder about these stubborn Vundos, can they be time bombs? Here is the latest MBAM log (post-reboot)

OK yes there are no shortcuts with this. You will need to Update the MBam and rescan.

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.

If you still show something then run SDFix...

Please print out and follow these instructions: "How to use SDFix". <- This program is for Windows 2000/XP ONLY.
When using this tool, you must use the Administrator's account or an account with "Administrative rights"
  • Disconnect from the Internet and temporarily disable your anti-virus, script blocking and any real time protection programs before performing a scan.
  • When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt.
  • If SDFix is unable to run after rebooting from Safe Mode, run SDFix in either Mode, and type F, then press Enter for it to finish the final stage and produce the report.
  • Please copy and paste the contents of Report.txt in your next reply.
  • Be sure to renable you anti-virus and and other security programs before connecting to the Internet.
-- If the computer has been infected with the VirusAlert! malware warning from the clock and the Start Menu icons or drives are not visible, open the SDFix folder, right-click on either the XP_VirusAlert_Repair.inf or W2K VirusAlert_Repair.inf (depending on your version of Windows) and select Install from the Context menu. Then reboot to apply the changes.

Hi again boopme! OK I've run the SDfix and MBAM again, MBAM is still showing the same 5 infected items even after reboot. At least they dont seem to be doing anything, all the redirects, adware, etc. have stopped.
