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.

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.

Best practices for resolving firefox issues

A clean and tidy computer is the key requirement for avoiding problems with firefox. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off doing a repair of your installation, or in the case of Windows 8, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the firefox.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
