[freedom]] This is a post not regarding any algorithm but a very general topic.Virus in Linux , although I am no genius to talk about this issue , it's just because this topic has fascinated me and I would like to share my little bits of knowledge with you.
Virus, everyone knows what they are and Windows Users need to grapple with them every single day, but what's with Linux ,does Linux have viruses, you sure have Anti virus softwares for Linux which can be downloaded using Package Manager .
But Linux OS is well protected , no OS is immune to virus attack and moreover when your code can be seen by million eyes across the globe . Linux community also provides latest security updates that help in saving your accounts from virus attacks.
Linux OS is hence more stable than windows for virus attacks and no single big malware attack has been witnessed in Linux , although as popularity increases virus attacks will sure be on the rise.
Linux also does a pretty cool thing by locking one's root account and using sudo command which is also used in Mac while using root you are the master and changes apply system wide, which does not happen with sudo , which asks for your password while entering any command , graphical commands (gksudo) for gnome , you get a 15 minute timeout for a terminal for using sudo within which your password will not be asked .
Also if one has to hack your system he needs to know your username not just hack your password.That is why it is more advisable to use sudo rather than go for an easy alternative of root.And your file permissions provide you a safe haven from these attacks.
To protect your system more you can also set passwords for you grub and BIOS .
So nothing is virus free in this world and nothing is impossible to hack ......
So keep on trying.............someday you might triumph .
