Hi,

I am using an IBM Thinkpad connected to the Internet through a Belkin G Wireless router which plugs into a Paradyne ADSL2+ router connecting to the Internet through the phone line.

My system seems to have contracted the Trojan.FakeAlert infection. The Task Manager is grayed out, Regedit is inaccessible, control panel is gone from the start menu and msconfig does not let me make any changes to the programs scheduled to run at startup or services etc.

System time is changed to Military time with the seconds indicator changed so the time shows as "22:21:VIRUS ALERT!"

There are lots of popups suggesting that I have been infected with Worm.Win32.Netbooster worm and should buy an antispyware software to fix the same.

They are also followed with lots of websites popping up that say that a online scan is in progress or I need to buy software to do so etc.

There is a red circle with a white x in the system tray which keeps giving a similar notification asking for buying the antispyware.

The All programs, Control Panel, My documents, My computer etc icons are gone from the Start Menu.

This happened while I was online and I noticed a Command Prompt window flash by indicating that some files had been copied to C:\program files\PCHealthCenter. I managed to delete the files in that folder but that does not seem to have solved anything.

The system is really slow as well now, something I have never experienced.

Can somebody please help me resolve this?

Regards

Hi and welcome let's start by running this..

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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. 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 you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Hi,

thanks for the prompt response.

Here is what happened.

I d/l MBAM and updated it and then ran the scan. It found 30 infections.
While attempting to remove them, got an error message stating Regedit has been disabled and will affect the quarantining process. MBAM will now enable regedit. I clicked ok.
Next I got an error message stating Registry editing has been disabled by your administrator. I clicked ok.
Showed the first message again and then went through without any further error messages after that MBAM needed to restart to complete cleaning. I clicked ok.
Log file showed up and system restarted
1. System configuration utility popup came up suggesting that configuration changes have been made and I need to undo changes made. I clicked ok to get rid of it since this message shows up everytime you use msconfig to disable any startup item.
2. Got an error message that "An Access Denied error was returned while attempting to change a service. You may need to log on using an Administrator account to make the specified changes." even though I am an administrator account holder. I clicked ok.
3. Got an error message asking me to restart or exit without restarting since I have made changes to the system config utility.I clicked ok.
Select exit without restart
Ran MBAM scan again
Found 17 infections.
MBAM attempted to fix them. Again asked me to restart to clean a few infections.
Restarted the computer. Again came across messages 1 and 2 above but not 3.
Ran MBAM again.
Found 15 infections. Log file appended -

Right,

While awaiting guidance from the excellent folks on this site, I let MBAM fix whatever it had found again, and after the inevitable reboot, to my horror I lost audio, right click, quick launch, no icons on taskbar even though i can do alt-tab, applications will not start, Services MMC Extended view is blank, no printers, cannot cut and paste, cannot do much of anything. Control panel > Admin Tools > Services I get and empty tab for extended services. It appears that all of the standard services are present (but none started) and network connections is blank meaning i cant go online.

And btw, MBAM failed to load too, indicating an error on some ocx file

Device Manager looked normal.

Did some googling and tried expanding oembios.dat, secupdt.dat. no luck.

Regsvr32 on a bunch of dll, all went through to no avail

SFC/Scannow, nothing.

Attempting to go into safe mode got me stuck at loading mup.sys

Visions of clean reinstall of windows, losing recent data and all the headache around reinstalling apps were circling in my head when I came across this MS KB article -

http://support.microsoft.com/kb/314357/EN-US/

I did as it said and then went into services and started all the services that I could think of like RPC, Network Connections, RPC Locator, DHCP, COM+, etc.

Next I deleted the drivers for the 3 network cards and the sound card and rebooted.

Voila, I now have a functional taskbar, copy paste, I have audio and the network icons are back up.

Scanning MBAM again. Shall post outcome soon.

Hi,

thanks for the reply.

I attempted to login to the safe mode but the system gets stuck at mup.sys and does not go any further?

I have tried it many times to no avail. I can login to normal mode ok. though the system startup takes 2-3 minutes longer than earlier.

Please suggest how do I get safe mode to work because that has proven to be a lifesaver on many occassions in the past

regards,

Hello soory for the delay. I was reading many items on this . I feel one you can run thise from normal and even Update and run MBAM again. Perhaps we get lucky and it fixes it. We don't want to force safe mode. Next option would be to podt a HJT log. The final solution and the one I've seen most is a Reinstall of the OS. So what do you feel like doing.

Hi, thats ok.

I appreciate your answering this.

If all came back clean and there no signs of infection then do this now...

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"
  • 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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
