Some of the points the others have made are very valid, however my advice would be...... be cautious of any software that you utilize over the network.

As linux gains in popularity, it also presents a challenge to the writers of malicious code and their evil intentions!

Dont live in a 'fools paradise', they also have linux in their sights!
Only problem is, there are so many distro's, they dont know where to start...lol!

Regards to all!
yes at any time it is better to cautious.I faced several problem and virus attack previously due to my casualness.so its better to be alert with any program you run

Personally I believe Linux comes with more precautions, like you have to chmod to execute something, and running as root user is almost unheard of.

Yeah, sorry but you're completely wrong. All ports are closed on any OS. However Linux has a builtin firewall(netfilter/IPtables), you can use it to stealth your ports, great thing about IPtables is it uses netfilter which is built into the kernel. part of the reason linux doesn't need an AV is you need to be root user to have write acess to anything outside your home folder(unless you change that). Another thing that helps is file permissions, not allowing a file to execute unless given the proper permission through CHMOD(system call, or shell command).
NOTE: sudo doesn't apply to real life situations.

because it has a great security. and latest patches are available every day so if OS doesn't have any patch then how virus attack on it.

Since I use Linux. My PC with Window was struck by virus twice in 3 months and my Linux PC has none so far. Hope it stay that way.

Why linux does not have viruses

This is because most of the viruses are .exe files which are not executable in Linux Operating system. In other words the OS does not understand what the files are.

Well exe files are windows binarys, not compiled for linux. There are 4 main reasons linux doesn't need a AV:
  1. Linux uses file permissions, you can only execute a file if you have a "+x" permission.
  2. A typical linux user only has write access to his/her home folder limiting the virus to a small area that contains no important system components
  3. Root users are(by default) the only user that has write access outside its home folder(/root); The root user is only used to make changes to the system, which normal users cant. No one in the right mind ever runs as root to do everyday tasks. A user with sudo privledges can use the "sudo" command to run a single process or command as Root user.
  4. Patches, Linux is the most rapidly developed software on earth. Patches come out very rapidly and there are so many contributors that a loop hole will only last a few days

Not too mention there are security addons for linux such as Apparmor, SELinux, and many more which provide "Mandatory Access Control".
NOTE: sudo doesn't apply to real life situations.

Can tell all this in one sentence

"People Love Linux more than Windows"
"If people start hating it then bulk of virus can start their war"
