Firefox will not let me get on any websites (safe AND not safe), claiming that it "may pose a security threat to your system"; when I try to choose the "proceed unprotected" option, it won't let me.
My computer's anti-virus software recently expired. A few days later, I went to download a new anti-virus software . . . when I opened up Firefox, I received a warning that claimed Firefox was infected with "Trojan-BNK.Win32.Keylogger.gen", and gave me two options: "Activate XP Security 2011 (recommended)" (this was a $60 charge and required credit card info) or "Continue unprotected (Dangerous)"
Since I needed to install new anti-virus, I figured I would continue unprotected, download my new software quickly, and remove the virus. But when Firefox opened, it gave me a message saying: "Firefox alert. Visiting this site may pose a security threat to your system!". Gave me three options:
1. "Get a copy of 'XP Security 2011' to safeguard your PC while surfing the web (RECOMMENDED)"
2. "Run a spyware, virus and malware scan" (I already did this)
3. "Continue surfing without any security measures (DANGEROUS)"
I tried clicking on different links, but the same warning kept showing up, even on verified and safe sites. I tried to choose the third option so that I could download my anti-virus software quickly, but nothing happened when I clicked on it - the page reloads and the warning shows up again.
My computer is still without anti-virus software because Firefox will not let me surf the internet. Please help!

It sounds as though your PC is infected with fake antivirus software. The detailed cleanup instructions vary depending on which fake AV you have. However, as a first step, try this:
Download the following on a different PC, copy them to a USB flash drive or CD, and then run them on the infected PC:
Malwarebytes Anti-malware : http://www.malwarebytes.org/mbam.php
SUPERAntiSpyware : http://www.superantispyware.com/
Hopefully these will get you back online safely. If not, search for clean-up instructions for the specific malware.
