If you use a computer, you may know that some malicious programs may damage your computer. And you can also know the names of these programs are viruses, worms and Trojan horses. However, many people don’t know why these programs have these names and how they work and what happens when they enter our computer.
You should be aware of what are the enemies in cyber world and also how fast is spreads across people in the world. Apart from this you should also be aware of different types of enemies that exist in the digital world.
The most famous cybernetic enemy is of course a virus. Although all computer users know the virus, when the popular media published an article about the ILOVEU virus affecting millions of computers around the world, this cybernetic enemy has become the subject of global publicity. .
If the virus is known, other cybernetic enemies, such as worms and Trojan horses, are not well known to the public. Even computer users don’t know that they are very different from viruses and their operations.
How do worms and Trojan horses differ from viruses?
To understand this, let’s take the virus. This is a program that lets you access your computer through other files or programs without your knowledge. When you enter the machine, it can damage your program and make your computer behave abnormally.
However, worms are completely different things. This is a plan that has its own life. On your computer, you will copy yourself, which will spread through the computer network. It can take up a lot of bandwidth and shut down your computer. In other words, even if the virus corrupts the computer it is entering, the worm sends its clone or copy to other computers over the computer network.
In this way, worms are more dangerous than viruses because they can cause considerable damage compared to computers that are attacked by viruses. For example, a worm called Code Red made headlines in 2001. Experts believe that this worm will cause such damage and things will stop completely. In fact, the worm copied more than 250,000 at around 9:00 on July 19 of the same year.
Another worm called Storm appeared in 2007. It draws users to download it to their computers, which, according to experts, still survive and damage millions of computers around the world.
Like the mythical Trojan horse, the program enters your computer by hiding other software such as free games or free software. After cheating on his computer, he secretly completed his work without a computer user realizing his existence. In other damage that can cause your computer, the Trojan can remove your hard drive until it is too late and you won’t know it. What’s more, Trojan horses can send sensitive and important information from your computer to virus developers, and virus developers can take over your computer and turn it into a zombie computer. Unlike worms, Trojan horses cannot be copied automatically.
How safe are you from cyber attacks?
First, don’t download any Internet files or programs unless you know they are from an approved source. The same is true for attachments received using emails from people you don’t know. These attachments are the primary carrier of malware.
Also, take steps to protect your computer from external attacks. It starts with the firewall, this is your first line of defense. It helps prevent some or all of the virus and other malware from entering your computer. For the second line of defense, you need to install anti-virus and anti-spyware software to detect enemies in your computer and destroy them.
