Are there virus free operating system?

Answer 1

Yes. A very large variety of operating systems are available free of cost, and many with source code available.

Operating systems available free of charge, for any purpose, with source available:

• Linux - Unix-like OS
• FreeBSD - Unix-like OS
• OpenBSD - Unix-like OS
• NetBSD - Unix-like OS
• FreeDOS - MS-DOS clone
• ReactOS - Windows 2000 / XP clone (in alpha, not suitable for daily use)
• Haiku - BeOS clone (in alpha, not suitable for daily use)
• AROS - AmigaOS clone (lacks a web browser and good device support)
• KolibriOS - Floppy-size OS with a crude GUI
• Syllable - general desktop OS; Amiga-like.
• OpenSolaris - open-source codebase of Solaris (see below)

Operating systems available free of charge for personal use, without complete source:

• Solaris 10 - Unix implementation from Sun Microsystems. Useful as workstation / server; lacks comprehensive hardware support.
• BeOS Personal Edition - multimedia-oriented desktop; doesn't work on most newer computers.
• DR-DOS - MS-DOS clone
• MenuetOS - Floppy-sized OS with GUI.
• QNX - realtime / embedded OS; highly responsive environment, though mostly lacking in applications (you were supposed to write your own!)

Answer:Why you buy costly OS from Microsoft or some other companies. There are some othe popular operating system that work same like Microsoft' OS. Most of the OS are freely available to download and run on private machines.

Some are

1. DOS

2. RxDOS

3. Ubuntu

4. ReactOS

etc

You can find and download more free OS from the link that I have posted in the related links with this question.

Answer 2

There are loads and loads of free operating systems, most of them are distributions of Linux which come in many forms, perhaps the most popular of these being ubuntu due to it's ease of use. However there are other free OSs such as FreeBSD and a project that aims to make a free clone of windows XP.

Answer 3

Actually, Yes.

There are many operating systems out there which have no possibility for a malware to be written.

THESE CAN AND WILL GET VIRUSES:

Microsoft Windows is a real disadvantage in this, as any program (including malware) can be run and installed WITHOUT the user's permission, viewing this website with a bad line of HTML code will (theoretically) destroy your windows PC.

Linux is like this as well, however there is a real lack of LINIX programmers, sunce there are so many adaptations of LINUX around and thee tiny market share they own.

Most Smartphones: These will get viruses as quickly as windows will, for owners of S60 (the most used smartphone in the world) this is a severe problem.

THESE MIGHT GET MALWARE IF YOU ARE AN IDIOT:

Mac OSX: Mac does not get malware simply from viewing a site, but DO get malware if you really go out of your way to put it on. You will have to manually download a file from somewhere (an untrusted site), wait for the download, manually install the software, allow extra permissions to the file system, do this, do that... virtually impossible

Regular Phones: These run the J2ME Operating system, which has to be configured to work alike MAC

IMPOSSIBLE:

iPhone, iPad: Software has to be certified by Apple and downloaded from the Apple website. You can't make your own software (unless Apple gives YOU permission for a hefty sum of cash). You can however get malware is you hack (jailbreak) the iPhone with your computer and install a similar operating system

- It is understood that "VIRUSES" are actually a specific type of malware (malicious software) which involved corrupt and coding changed OFFICIAL FILES (totally recoding internet Explorer 9 to becoming a media Player is an example). I substitute MALWARE for VIRUS as malware is really anything you don't want (like most stuff which steals your credit card details which AREN'T viruses), rather than a specific type of bad software.
