Why Linux Will Never Suffer From Viruses Like Windows ??

Question

What is the difference in behavior between mutex in linux and mutex in VxWorks ??

Answer 1

Any computer that is attached to a network is not immune to viruses.
If you compare the vulnerability of Linux to Windows, you can understand why so many say Linux is immune.

There are some reasons to that:

1. There are numbers of distributions of Linux. At Kernel Level they all are more or less the same but not at the OS Level.
   Now suppose a malicious script is written for a RPM based system i.e., RedHat, Fedora, CentOs, it can’t infect a Debian based system and and vise versa.

2. And above all those script that is going to perform a system-wide change needs root password. If the password is strong enough, the OS is literally secure. while in windows you can do it as a normal user.
