Ubuntu provides a very secure working environment and is not plagued with viruses like Windows. One reason for this is the way Ubuntu handles file permissions which makes it very difficult for any virus to spread.
Hi! This is Mike Callahan, Dr. File Finder and welcome to part four of our special butterscotch.com 10 part series on Ubuntu. Now, on this segment, we’re going to look at security. I'm here on a Wikipedia page about Linux malware. And I've highlighted this part. It says, the Linux operating system, Unix, and other Unix-like computer operating systems like the Mac, I generally regarded as well-protected against computer viruses. There has not been a single widespread Linux malware threat of the type that Microsoft Windows software currently faces. Part of the reason for this is the way that file permissions are handled in Linux of which Ubuntu is a part. Here’s another article about why Linux users don’t worry about viruses. Interesting statistic, the total number of Linux viruses found ever is just 7.9% of the Windows viruses found from July to December of last year. And that was 2007. And in case you're wondering, there are estimated 114,000 total known Windows viruses. So, this is one reason that Linux is extremely secured. And when you install Ubuntu, there are al kinds of software that is included with Ubuntu but antivirus software is not among them. So, the way Linux handles administrator privileges, files permissions, and so makes it extremely difficult for viruses to succeed in Linux and Unix based operating systems. So, Ubuntu is extremely secured and that concludes part four.
