Is linux totally virus free ?

hi

Most of my friends told me that in inux you will not find any virus. it's totally virus free O/S. so I just want to know that is linux totally virus free ?

Thanks

*NIX(BSD's,MAC,LINUX,MINIX etc) Platforms are inheretently immune to viruses.may be some worms are there which does the harm,but they too cant do much as they need a security vulnerability like in user permission options etc.

Though project like reactos can be attacked by viruses,trogens etc etc/

Be it a hoax or reality,tuxissa virus should have been necessary for all Windows Users to understand the features of Linux.

If you are careless with firewall hackers can access you computer (Novell's default firewall settings are good enough to stop most hackers cold). Even FBI database isn't hacker proof (Russian KGB and Serb guys have shown that) so you can't totally ensure that. But you can rest in peace in Linux as hacking it isn't as ABC like Windows.

BIOS viruses are OS-independent and so a potentially greater threat. The flash memory is usually unscanned by virus scanners, as well. However, BIOS viruses have had something like ten years to emerge and really haven't been as much of a problem as initially predicted. With the increasing popularity of flashable firmware and "intelligent" devices and daughter cards, you'd expect to see problems there too, but that's so far not happened.
