Many risks make modifications to the registry, which could impact the functionality or performance of the compromised computer. While many of these modifications can be restored through various Windows components, it may be necessary to edit the registry. See in the Technical Details of this writeup for information about which registry keys were created or modified. Delete registry subkeys and entries created by the risk and return all modified registry entries to their previous values.

RESTORE DOMAIN NAME SYSTEM (DNS) SETTINGS

1. Check if the DNS server settings have been modified by the adware (based on the samples we have, the DNS servers will be changed to 31.168.224.100 and 5.135.12.56).

If this is the case:

For Windows XP users:
  • Click on the Start button
  • Go to Control Panel
  • Double click on Network Connections
  • Right click on your active connection
  • Click on Properties

For Windows Vista/7/8 users
  • Open Windows Start Menu
  • Click on Control Panel
  • Go to Network and Sharing Center
  • Click on your Connection Type (ethernet, local area network, or wireless). This should launch a window showing your connection status
  • Click on the Properties button
  • Click on Internet Protocol(TCP/IP)
  • Click on the Properties button

Once you have reached the Properties screen, enter the manual DNS server address if it is provided by your internet service provider. If it is not provided, select "Obtain DNS server address automatically".

When you are done, keep clicking on the OK button until you are out of the Properties screen.

2. The adware may modify the web browser's settings. For each web browser that you have installed, please follow its instructions on how to reset the browser to its default settings. Please note that this method will remove all add-ons, extensions, toolbars, and other customization features.
