You do need an anti-virus application - period. What were you using before you installed Firefox?

Firefox is a web browser as it does not come with a antivirus or a firewall.

Hello: I am just simply trying to find out what kind of anti virus d0 I use with Firefox. I am looking for a free versions and there are so many out there. I tried downloading Microsoft Security Essentials, but had problem with it. I am waiting for a response from Microsoft about this issue. Thank You and if I get a response, it would be so appreciated.
