(OPTIONAL) STEP 6: Reset your router to the factory settings

In recent attacks, cyber criminals are infecting the router to redirect the traffic to different websites. Resetting the router to the default settings will remove the malicious redirects, however you will need to reconfigure all the settings.

  • Router username and password
  • Wi-Fi username and password
  • ISP username and password
  • Any port-forwards you have set up
  • Any firewall settings you have made
  • Basically, any configuration changes that you have made to your router.
As you can probably tell from the list above, resetting your router is serious business. Proceed with caution.
If you do not know how to configure a router, you should not perform this step.
  1. To reset your router find the tiny reset button usually located at the back of the router. While the router is on, use a pin or the end of a paper clip to press and hold the reset button. You will need to hold if for about 10 seconds.
  2. Reconfigure all the settings of your router (example: ISP username and password, Router username and password)

Your computer should now be free of the WARNING! Your Flash Player may be out of date adware. You can remove AdwCleaner from your machine, however we recommend that you keep Malwarebytes Anti-Malware and HitmanPro installed to perform regular computer scans.
