Remove Questscan at Firefox

If you get infected by questscan when you type at address bar it will go directly to questscan.com instead of your search result.

1. Uninstall it, go to c:\Program Files\QuestScan\Uninstall.exe.
2. Remove the plugin. Type about:config at Firefox address bar. Type keyword.URL at the filter input box. Right click on this preference line and select Reset from the pop-up menu.


Already test it and working good.
