Hi there! My anti-virus always pop-ups because of that Trojan, i recently upgraded my PC but in my surprise i was already infected. It happened when we forgot to scan my cousin's USB flash disk when we are transferring some files. First an error appears that says...

"The instruction at "0x0164f496" referenced memory at "0x0164f496". The memory could not be "written".

Click on OK to terminate the program
Click on CANCEL to debug the program.

The sound of my computer mysteriously disappears after the error occurred, and while playing some online games my internet connection times out.

My desktop seems to freeze whenever i close an application but the cursor responds.

Also the appearance of my taskbar switches from the xp theme to classic and resets back to xp appearance.

I consulted my cousin and he encountered the same problem and consulted here at this site. The problem were solved and i hope you can help me too. THANKS! :thumbsup:

Hello jerico228 and :thumbsup: to Bleepingcomputer

Let's see if we can nail this bugger :flowers:

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate 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.
  • 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.

Your machine appears to be clean!

I highly recommend that you read through the below set of very helpful suggestions and implement them; they will help protect you from reinfection

Disable and Enable System Restore. - You should disable and enable system restore to make sure there are no infected files found in a restore point. You can find instructions on how to disable and enable system restore here: Windows XP System Restore Guide

Re-enable system restore with instructions from tutorial above.

Next, please hide your System Files. To do this, please refer to the following guide and reverse its steps: "How To See Hidden Files in Windows."


This should give you a good start into malware free pc usage. However I do suggest to visit the following additional information listed below:I recommend you regularly visit the Windows Update Site!
  • Lots of Hacking/Trojans use the methods found (plugged by the updates) that have not been stopped by people not updating.
  • By updating your machine, you have one less headache! Posted Image
  • Update ALL Critical updates and any other Windows updates for services/programs that you use.
  • If you wish, you can also use automatic updates. This is a good thing to have if you want to be up-to-date all the time, but can also be a bit of an annoyance due to its handling and the sizes of the updates. If you wish to turn on automatic updates then you will find here is a nice little article about turning on automatic updates.
  • Note that it will download them for you, but you still have to actually click install.
  • If you do not want to have automatic updates turned on, or are on dial-up, you can always download updates seperately at: http://windowsupdate.microsoft.com.
It is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.

For a nice list of freeware programmes in all categories, please have a look at this thread with freeware products that are regarded as useful by the users of this forum: Commonly Used Freeware Replacements.

Another recommendation, is to download HostMan. It safeguards you with a regularly updated Hosts-file that blocks dangerous sites from opening. This adds another bit of safety while surfing the Internet. For installlation and setting up, follow these steps:
  • Double-click the Downloaded installer and install the tool to a location of your choice
  • Via the Startmenu, navigate to HostsMan and run the program.
    • Click "Hosts" in the menu
    • Click "Manage Updates" in the submenu
    • Out of the three, select atl east one of them (I have MVPS Host as my main one)
    • Click "Add Update." After that you will only need to click on the following button to retrieve updates:
      Posted Image
  • Click the X to exit the program.
Finally, and definitely the MOST IMPORTANT step, click on the following tutorial and follow each step listed there:

Simple and easy ways to keep your computer safe and secure on the Internet

Glad I was able to help and if there any other problems related to your computer please feel free to post them in the appropriate forum. Though we help people with spyware and viruses here at BC, we also help people with other computer problems! Do not forget to tell your friends about us!
