I too have been infected with this and maybe more. I ran Malwarebytes on the infected computer and after a resart I could not open any program without being prompted to find a program to open it with, I'm thinking I must have deleted some important .exe files so I rolled back my computer status to earlier in the day before I used Malwarebytes and did another scan. Can someone please help, I'm not a tech saavy guy but I can follow instructions if someone can help?

Hello,I split you to your own topic.

After rolling back can you open programs if so do this.
What is your operating system?

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices
  • List Users, Partitions and Memory size.
  • List Minidump Files
Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.


Did MBAM find anything? post that log.

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.

Ok, sorry for the delay. I'm running windows 7 64 bit. I ran Malwarebytes a second time and tried it, it seems to have worked this time, at least I have not noticed too much going on out of the ordinary, no more pop ups for windows 7 antivirus 2012. Here is the Mbam log:

OK that was good that should be the troublemakers.
We should do a last scan for spinoffs and/or remnants.

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and check Remove found threats
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • 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 Posted Image
  • Push Posted Image, 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 Posted Image button.
  • Push Posted Image


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

When a browser runs an applet, the Java Runtime Environment (JRE) stores the downloaded files into its cache folder (C:\Documents and Settings\username\Application Data\Sun\Java\Deployment\cache) for quick execution later and better performance. Malicious applets are also stored in the Java cache directory and your anti-virus may detect them and provide alerts. For more specific information about Java exploits, please refer to Virus found in the Java cache directory.

Notification of these files as a threat does not always mean that a machine has been infected; it indicates that a program included the viral class file but this does not mean that it used the malicious functionality. As a precaution, I recommend clearing the entire cache to ensure everything is cleaned out:{Thanks to our quietman7}


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 Posted Image > 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 Posted Image > 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.
