In general, in the present day and even in the future, people can almost live without the internet, it has become an essential need of each of us.

So in the midst of such a large internet world, how can you always be safe while surfing the web, I mean how to use it to avoid getting virus on your computer as well as being scammed on the internet?

As you know, everything has two sides of it and often what is interested by many people and widely used will be exploited by hackers to thoroughly exploit the vulnerabilities, to deceive users.

I take for example Microsoft's Windows operating system, it is not that this company has poor security but because its Windows operating system is too popular and almost all computers in the world use the system. Because of this, every day it is scanned by thousands and tens of thousands of hackers, looking for loopholes to take over the property of others.

Many of you say that the Linux operating system is more secure than Windows, but it is not, but the reason is that Linux is not popular enough for hackers to exploit.

Back to the main problem today, in this article I will list 13 basic principles that you should know and should apply immediately if you do not want to one day be the victim of a hacker.

1. Use Antivirus

This is the minimum thing you should do for your computer, if possible, you should use premium software such as BIT, Kaspersky . otherwise choose one of the  free anti-virus software. .

2. Scan for viruses before downloading and installing

You should scan for Viruses all the tips, attachments in the email before clicking to download or before installing and using them. You should immediately apply online virus scanning for URLs or files.

3. Access to reputable websites

You should only  download the software  on a few reputable sites that are trusted by users. And especially should read comments of previous users (if any). Or perform file virus scan before using (application note 2).

Tips: During the search process, you should remember and filter out some good websites so that when you need to find information, it will be faster and more accurate.

4. Absolutely not sharing information, passwords

You should not share information as well as passwords of different types of bank accounts, email accounts, forum accounts . with strangers, or even people you consider "close" on the internet but in fact are you. never met V

Because in real life, meeting daily is also a scam, let alone the virtual world. That's why don't trust too much. 

5. Note set password and login

+ Absolutely do not set a password like 123456, abcxyz, qazwsx, your name, or your date of birth…. You should set a slightly difficult password like this one haHa @ $% (Generally you should combine uppercase, lowercase letters and special characters).

+ When sitting on a computer in a public place, that is not your computer, it is best to limit login to an important account and one more thing to note is that on today's web browsers when you log into your account, The Save Password section will appear.

You absolutely must not click save, others can easily know your username and password in the Password Management section of that browser.

And if you have last clicked then you should clear the history by pressing Ctrl + H and erase it all (remember to check everything, including the password).

+ On   today's popular browsers often support anonymous surfing, if you sit on a public computer, it is best to use this mode to not be saved search information as well as login.

1. In Google Chrome / CocCoc: Use the key combination Ctrl + Shift + N
2. In FireFox browser: Use the key combination Ctrl + Shift + P
3. Read more:  Set Chrome to automatically open Guest mode

6. Update software / operating system regularly

If you update the software, the operating system to the latest version is the best, because these versions are often updated as well as patches of older versions.

Note: If the software or the operating system notices that the current version is vulnerable to security holes, now you must upgrade to it if you want to be safe. (Keep track of the information on its homepage).

7. Access the correct URL of the Web site

One of the reasons why you get hacked is that you access the wrong website address. For example, my web is blogchiasekienthuc.com but you go back to blogchiasekienthuc.net and then die.

That is an example for fun, but in fact, a lot of people lose their facebook account because they log in to a page that has an interface similar to that of Facebook, but the most important thing is that the URL on the Address bar does not notice. So be alert and check the web address carefully before logging in.

8. Pay attention to https or http protocol

For big websites such as social networks, google products (gmail, youtube .) or sites about banking, securities, online payment, they often use SSL (Secure Sockets Layer) https instead. because http is like regular web pages.

1. Normal site example: http://www.youtube.com/
2. Web using ssl protocol: https://www.youtube.com/

Note: The https protocol is always more reputable and secure than the http protocol.

9. Use Email wisely

Hackers and hackers always take advantage of users' lack of understanding and experience to send Spam messages, spam messages containing malicious code in them.

Ideally, if you are unsure about the content of that email, you should not try to do anything, if you happen to go a thousand miles.

The latest scam is that hackers used fake Microsoft email to tell Windows users that Windows 10 is ready and free, you can download.

Once you download and install it, your computer will immediately be locked by CTB-Locker ransomware. And at this point Ransomware will ask you to send payment within 96 hours or else you will be permanently encrypted to your computer files.

Another important note is that after you are done using it, instead of turning off the browser immediately, you should exit your account before closing the browser.

This prevents you from exposing important information, or you can apply note 5 above.

11. Absolutely do not log in sensitive public accounts

You should not log into important accounts such as bank accounts, online transactions in public places such as cafes, public wifi, public computers . Because these public machines are susceptible to infection. Spyware is very advanced.
