Hello!

Yesterday Ad-Aware detected a problem and attempted to remove it. Ad-Aware said it was successfully removed. It was:
Win32.TrojanD\..\der.Mufanom/A

After removing it though, the programs on my computer have been very slow to respond. I scanned it again using Ad-Aware, this time doing the full scan, and it found the same Trojan, but no other viruses/problems. I again removed it and experience the same slowness afterward.

I also ran SpyBot and it did not detect any problems. I always have ZoneAlarm and SpywareBlaster running.

I have Windows 7 & use Firefox.

The only other odd thing happening is, after removing the trojan the first time, at start up I receive these messages:
Cannot open the file C:\Users\..\AppData\Local\eyacuficawa.dll
Cannot open the file C:\Users..\Local\Temp\noteutil.dll

Oh, and I tried to do a system restore and got the message that it couldn't restore because it couldn't get to a file probably because of an anti-virus program. I disabled Spyware Blaster and tried again but got the same message.

I googled Mufanom and it sounds like a nasty one, but is there anything I can do beyond purchasing SpyHunter?

Any insight into this would be much appreciated!

Hello, this looks like a Tro.Hiloti infection... Let's do thises and see.
Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.Download Link 1
Download Link 2
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. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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 definition 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. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.



Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.


Please ask any needed questions,post logs and Let us know how the PC is running now.

Yes, you were right about the type of virus it was! Thanks for your help!!

I followed your instructions, ran Malwarebytes, was able to run AFT and SAS in safe mode, and the computer seems to be back to normal. My only concern is that I received a message from Malwarebytes that they were not able to remove some files. Yet the log looks like everything was removed. Both logs are posted below. Any thoughts on why I received that message?

Hello, good results. It may have been the The Malware the couldn't be fixed will be fixed on reboot type message... I forget the exact wording myself but it appears you rebooted and it got it.

Let's do 2 more scans and see how we are.

  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the ESET Online Scanner button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Export to text file... to download the ESET Smart Installer. Save it to your desktop.

  • Check the "YES, I accept the Terms of Use"
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Check Scan archives
  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push "List of found threats"
  • Push "Export to text file", and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the "<<Back" button.
  • Push Finish
In your next reply, please include the following:
  • Eset Scan Log


NOTE: In some instances if no malware is found there will be no log produced.

Hi,
Looks like the processes worked! ESet didn't find anything (and didn't create a log) and MBAM looks clean too. Thanks for your guidance!

Looks good here.. I'll leave you with some of our quietman7's tips.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, 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 malicious 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.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:
