Firefox is a good browser and is certainly less prone to attach by virus. However, new release are becoming more and more compatible with Microsoft and its threaded internet explorer. Any browser is prone to attach however there are few out there less used such as opera and safari these would be great alternatives to the the big 2

First off, THOSE VIRUSES ARE NOT FIREFOX, they are a trojan masking as Firefox. Firefox is a web browser by Mozilla, it is one of several F/OSS web browsers. Your virus warning is going to make people believe all versions of Firefox are bad, if you have a trojan masking as a program use only one red dot. I prefer chrome, but i also usually install Mozilla Firefox. TIP: Safari and Iexplorer are horribly slow and bulky browsers, always get a third party like chromium or firefox.

Mozilla Firefox browser
firefox.exe is safe if you have Mozilla Firefox 3.0 or above and are running the browser. However, if it runs without permission, starts without user command, starts at startup without proper configuration, or other things, you probably have a trojan or a worm. For the browser on Win7/Vista I suggest you get an /ftp/ version so that it downloads directly from the server. Also if you have a plugin running plugin-container.exe will be in task manager.

Best Browser on the Interwebz. However acts like a virus when bad flash and javascript is nearby.... COMON MOZILLA, re-create your javascript engine, needs to be as good or better than Google Chrome's .JS Engine.
  Won't Convert to Chrome.
