Having some virus problems today.

First of all I got infected with the Vundo virus. Not sure how, haven't downloaded let alone ran any EXEs in ~3 days. I scanned with SuperAntiSpyware in Safe Mode which seems to have got rid of it, but not all of it. It left some files running the next time I booted that complained of the .dll files that were deleted (which I think I've fixed), I clicked OK and everything seems to be OK so far.

There are 2 main problems:

However, randomly, when I click links in Firefox or in Google, I get redirected to Google-Redirect.com which redirects me to Google. My only guess is that Vundo wasn't completely deleted.

In explorer, I can't see file extensions any more, and the Tools -> Options menu option in Explorer is hidden (I can only see 3 results under the Tools tab, no 'Options').


Thanks in advance.

Hi, let's also do a MBAM scan and see what it finds.

Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.36) 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.

Hello..
Not an unwise decision to make. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. If you decide to reformat, you can back up all your important documents, data files and photos. The safest practice is not to backup any autorun.ini or .exe files because they may be infected. Some types of malware may disguise itself by adding and hiding its extension to the existing extension of files so be sure you take a close look at the full name. After reformatting, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

The best proceedure is a low level format. This completely wipes the drive. Then reinstall the OS.
Use the free version of Active@ KillDisk.
Or Darik's Boot And Nuke

The best sources of Information on this are
Reformatting Windows XP
Michael Stevens Tech

Of course also feel free to ask anything on this in the XP forum. They'd be glad to help.
==============================
2 guidelines/rules when backing up

1) Backup all your important data files, pictures, music, work etc... and save it onto an external hard-drive. These files usually include .doc, .txt, .mp3, .jpg etc...
2) Do not backup any executables files or any window files. These include .exe's, .scr, .com, .pif etc... as they may contain traces of malware. Also, .html or .htm files that are webpages should also be avoided.

Thanks, but I think I'd rather not format until I buy Windows 7 or some other really drastic problem occurs. As I said, everything appears to be working fine for now.

Ok, that cool..

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.

OK, this isn't over yet it seems.

My PC just restarted itself and then gave me a popup telling me I was infeced with Win32/Brotok and directed me to some dodgy antispyware site (pdefender or something). Now malwarebytes crashes when it looks for an update..

I don't know what to do next.

Hi, did the MBAM scan work? As you didn't post a log?
Did you mean Brontok? If so

Please download the Brontok Disinfection Tool and follow the instructions posted by Sophos.

When done, please download the Brontok Worm Removal Tool by sUBs and save it to your Desktop.
Disconnect the computer from the Internet and close all other programs.
Double-click CleanX-II.exe and follow the prompts.
The tool will begin scanning your machine. Because this worm names it's files randomly, there are a series of cross-checks/verification processes to ensure that the tool does not remove legitimate files. Depending on the size of your drives, this scan may take several minutes. Please be patient during this period & allow it to complete it's task.
Once the scan is complete it will provide a text log of the results. If the log shows any files remaining in the bottom portion under "POST RUN ANALYSIS" run the entire scan a second time.
