Faced any Malware, Reported Attack Site or This site may harm your computer? and successfully cleaned everything from your site? and completely managed to remove these attacked messages from Google and other major search engines?
But still facing the "Reported Attack Site" in Firefox?
Recently I faced the same issue and started exploring on how to remove this "Reported Attack Site" for our site and here is the simple solution for it:
Find this folder in Windows:
* C:\Documents and Settings\Administrator\Local Settings\Application Data\Mozilla\Firefox\Profiles\ieqtyuka.default
In Windows Vista and Windows 7:
* C:\Users\<Windows login/user name>\AppData\Roaming\Mozilla\Firefox\Profiles\
In Linux and Unix:
~/.mozilla/firefox/profile
In MAC:
~/Library/Mozilla/Firefox/Profiles/<profile folder>
or
~/Library/Application Support/Firefox/Profiles/<profile folder>
Find for the file named "urlclassifier3.sqlite" and remove/delete it to reset the settings, restart your Firefox browser and Happily browse your site :)
