The following information will help you both secure your computer straight from the start menu and help you restore you computer back to safety if it is ever compromised.
First, you should make sure that your firewall is turned on. Even if you know nothing at all about computers or security, turning on your firewall literally takes no skill, it is already pre-configured by your computer manufacturer and you just have to make sure that it is turned on. If you really want to take the time, I recommend going through your firewall’s settings, checking the rules and entering the terms onto a Google search just so you can learn yourself something new about them.
Second, if you haven’t done so already, you should encrypt your computer. If for some reason you are still unaware, “encryption” is just a fancy word for creating password entry. If you ever leave your computer unattended in a public setting or live in a house with multiple people, you should always makes sure that no one can use your computer without authorization. Meaning that when your computer starts, before anyone can physically access anything or do anything on it, they have to enter the correct password first. Setting this up is incredibly easy and you can edit or select this option straight from the settings on your computers start menu.
The next option is extremely critical, but is something which is often overlooked. You are going to want to make sure to disable remote access to your computer. Believe it or not, anyone whom knows anything about hacking can physically access/use your device through something as simple as Windows cmd if they share the same internet connection or know your IP Address. If you do not disable remote access to your computer you are essentially leaving the door wide open for anyone to walk through or exploit.
Lastly, if at any point in time you believe that you have downloaded any virus, Malware or Spyware, you can simply go to your computers start menu and search for “system restore.” All you have to do is find a date before you believe you contracted the virus, select it and restore you computers settings/files back to that date. This will restore your computers systems as it existed on that date. However, just note that while you will be losing the virus from your computer, you will also be losing all of the files, documents, pictures or anything else you have created or saved since that date. While it does not work every time or with some of its stronger versions, this should literally be your first move if you ever contract ransomware.
External Hard Drive
This next bit is something that I almost never see included in other online security tutorials, which is why I am including it here today. If you want a fool proof way to secure, protect and back up all of your most important files, you should invest in what is known as an external hard drive. You can buy a USB external hard drive in any major box store for anywhere from $75 – $200 and it fully ensures that if your computer ever gets compromised, all of your files and data is backed up.
External hard drives are extremely important if you wind up getting a serious computer virus, such as ransomware. An external hard drive will allow you to completely wipe your computers data, clear the virus off your systems and then re-load your files right back onto your computer as if nothing ever happened. Considering that most ransomware will charge your thousands of dollars to un-encrypt your data, an external hard drive back up is literally a $100 fix to a $1,000 problem. Always remember, backup, backup, backup your data – buy a USB!
Moreover, if you live in an at risk country and are ever worried about someone gaining remote access to or searching your computer, you can keep programs like Tor or TAILS on your external hard drive for safekeeping. If necessary, a USB is also much easier to hide or destroy if it ever comes to that point. You can also set up separate encryption for your USB, making it impossible to search without authentication.

Contrary to popular belief, even if you are using a “Windows Computer,” you do not actually have to run Windows as your primary operating system. While learning how to use and install Linux is not necessary and often times a useless nerd skill, there is no debating that Linux systems are far more secure than Windows or Apple will ever be. Therefore, if you are truly interested in learning a new skill or improving your cyber security practices, then learning Linux systems should be at the top of your priority list.
I am not going to teach you how to do this in this article or any other for that matter, that is what they make Google and YouTube for. Instead, I will just tell you what the world’s most secure operating system is; TAILS.

Sweet cmd Commands
If your network connection ever starts to become slow or your web pages simply aren’t loading as fast as normal, there is a simple trick that will automatically speed your internet connection back up, without disconnecting you from the internet or requiring your internet router to be reset. The best part is, not only will the following command sequence speed your internet connection back up, but it can also negate DDoS attacks and will kick any 3rd parties, such as hacker, off your computer/connection every time it is used.
Simply go to start menu, open cmd and type in the following sequence exactly as it is written below – don’t actually type “(enter),” that is simply where you press enter before typing the next command:
- title H4x0r (press enter)
- color a (enter)
- echo off (enter)
- cls (enter)
- ipconfig/flushdns (enter)
- ipconfig/release (enter)
- ipconfig/renew (enter)
Please note that only the sequence in bold is necessary, the first part is just for fun 😛
