Please download download Panda USB and AutoRun Vaccine and save it to your desktop.
alternate download link 1
alternate download link 2
  • Extract (unzip) the file to your desktop and a folder named USBVaccine will be created.
  • Open that folder and double-click on USBVaccine.exe to start the program.
  • Click Run.
  • Click the button to Vaccinate computer..
  • Insert your USB flash drive.
  • When the name of the drive appears in the dialog box, click the button to Vaccinate USB drive(s).
  • Exit the program when done
Note: Computer Vaccination will prevent any AutoRun file from running, regardless of whether the removable device is infected or not. USB Vaccination disables the autorun file so it cannot be read, modified or replaced by malicious code. The Panda Resarch Blog advises that once USB drives have been vaccinated, they cannot be reversed except with a format. If you do this, be sure to back up your data files first or they will be lost during the formatting process.

Please download Sysclean Package & save it to your desktop.
  • Create a new folder on drive "C:\" and rename it Sysclean - (C:\Sysclean).
  • Place the sysclean.com inside that folder.
  • Then download the latest Virus Pattern Files - (Pattern files are usually named lptxxx.zip, where xxx is the pattern file number)
  • Extract (unzip) the lptxxx.zip pattern file into the Sysclean folder where you put sysclean.com. (click here if you're not sure how to do this. Vista users refer to this link.) DO NOT scan yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Note: Some anti-virus programs will alert you of a virus attack when running sysclean so it's best to disable them before going to the next step.

Scan with Sysclean as follows:
  • Open the Sysclean folder and double-click on sysclean.com to start the scanning process.
  • If you get a message that required files are missing. Click Ok and wait for sysclean.com to unpack them.
  • Put a check mark on the "Automatically clean or delete infected files" option by clicking in the checkbox.
  • Click the Advanced >> button.
  • The scan options appear. Select the "Scan all local fixed drives".
  • Click the "Scan button" on the Trend Micro System Cleaner console.
  • It will take some time to complete. Be patient and let it clean whatever it finds.
  • Another MS-DOS window appears containing the log file (sysclean.log) generated in the same folder where the scan is completed - C:\Sysclean.
  • To view the log, click the "View button" on the Trend Micro System Cleaner console. The Trend Micro Sysclean Package - Log window appears.
    • The Files Detected section shows the viruses that were detected by System Cleaner.
    • The Files Clean section shows the viruses that were cleaned.
    • The Clean Fail section shows the viruses that were not cleaned.
  • Exit when done, reboot normally and re-enable your anti-virus program.
How to use Sysclean Package Instructions with screenshots if needed.

-- When using Sysclean its best to use the Administrator's account or an account with "Administrative rights" otherwise you will not have access rights to scan some locations. You can Use the "Run As" Command to Start a Program as an Administrator. Even when doing that, the scanning process may result in "Access Denied" messages for some files. This is normal because these files are protected by the system.

Please download Malwarebytes Anti-Malware (v1.38) and save it to your desktop.

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.

You're welcome.

If there are no more problems or signs of infection, 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 in Vista and Disk Cleanup in Vista.

Tips to protect yourself against malware and reduce the potential for re-infection:Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn 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. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn 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.Keeping Autorun enabled on USB (pen, thumb, jump) 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:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...

Microsoft Security Advisory (967940): Update for Windows Autorun
