I have tried for over 2 weeks, deleting registry entries in safe mode, changing browser settings, deleting addons, I have tried EVERY solution Google searches have to offer and this thing keeps coming back! All the solutions only work until a reboot happens or a few hours later. Is there any other way that I haven't found yet that will kill this thing besides FDisk?

Chosen solution

You should always pay attention when installing software because often, a software installer includes optional installs, such as this adware. Be very careful what you agree to install.
Adware gets on your computer after you have installed a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker.

You can use the below steps to revert back to adware-less Firefox.


1) Reset Prefs

  • Navigate to about:config in your Address Bar
  • Press the "I'll be careful, I promise!" button to proceed
  • Search for v9 and reset all prefs that pull up by right clicking > Reset

2) Remove any programs that you don't recognize or remember installing from your Control Panel (Start > Control Panel > Uninstall a Program)


3) Remove any extensions that you don't recognize or remember installing from Firefox.

  • Firefox 29 and above:(Go to the orange Firefox button > Add-ons > Extensions)
  • Firefox 28 and below:(Press the menu button (new fx menu > Add-ons > Extensions

4) Download ADW Cleaner to wipe out any remnants of the adware.


5) Do a malware check with some malware scanning programs on the Windows computer.
Please scan with all programs because each program detects different malware.
All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.
