Firefox has the following 2 warning screens for known phishing and malware sites. If you click "Ignore this warning" in the lower right of that screen, you are entering a know malicious site. *http://www.mozilla.com/firefox/its-a-trap.html *http://www.mozilla.com/firefox/its-an-attack.html If you are seeing something from your Security application, you need to contact them about that issue, with the name of the purportedly blocked virus/trojan/malware if it is given in the warning. If you are seeing a screen from some Security so-called application that you know is not installed on your system, it could be malware masquerading as anti-malware. Such a program is usually designed to entice you to buy, you give your credit card number and get nothing in return. They then have your credit card number to use to buy all sorts of items on the internet. So, which is it?
