Is windows vulnerable to viruses?

When talking about this topic, what you understand and do not understand will always think that Linux will hardly be affected by viruses, But windows will be infected with viruses as soon as it is accessed. This is a traditional concept, and today I want to give my mentor an explanation.

Statement: I have a long experience in using Windows and Linux. It is definitely not a special service sent by Microsoft, and my remarks are not without prejudice.

If you are a prawns, do not consider it a cainiao-level topic and leave immediately. Like many programmers wandering in csdn, we are both peers. The reason why we want to discuss this issue is, it is because many people who think they are windows programmers have not even figured out the Windows operating system.

Why is it difficult for Linux to access the Internet?

Linux is a multi-tasking multi-user operating system. Users have different security levels. root can do everything, while other users have restrictions. Linux on the desktop uses a file system with user security classification. Linux desktops run processes with non-root account permissions. Therefore, Web browsers and other related network processes run with low permissions, that is to say, even if the process contains malicious code, it cannot cause more damage to the Linux system. In addition, the number of Linux users is relatively small, and those who are willing to spend time writing malicious code are naturally fewer.

Let's look back at how we use Windows

Windows NT and later operating systems are also multi-tasking and multi-user, users are divided into different security levels, the administrator can do anything, other accounts are limited. However, we use the Administrator to log on, use the Administrator to start IE, and use the Administrator to do everything. At this time, the IE you use happens to be browsing a malicious website, so its code will run on your system with the Administrator permission. What does it do...

Summary

We say windows is more vulnerable to viruses than Linux. Is it unfair. We opened our own door to bring Trojan into the house, so that the virus could corrupt our system.

Supplement

Microsoft NTFS is a secure file system, and fat is not secure. Therefore, XP + Fat cannot constitute a secure system. It must be XP + NTFS.

I usually use a small-permission account to work and access the internet. Windows does not have permissions for many non-administrator accounts. The administrator user is used to install programs. In Windows, you can run a program in another account without logging out. Right-click the related options. This can really eliminate the headache of various viruses.
