Who will not be annoyed when the laptop or computer used is infected with a virus. Computer virus is a general term to describe any type of attack on a computer. Computer viruses generally can damage computer software and cannot directly damage computer hardware but can cause damage if left unchecked.
What can be felt as a user is that some computer performance will be not optimal, frequent errors, slow, the extension format on some files changes and cannot be used even to the point of surveillance and data theft.
For that, as users we need to know the types of computer viruses so that we can detect early when our computers are exposed to viruses. In Wikipedia, it is explained that there are 9 kinds of viruses.
The following are 9 types of viruses that exist and can attack computers, as follows:
Worm
This type of virus is not too dangerous. However, if it continues to be neglected and allowed to do so, it has the ability to multiply itself rapidly, causing the computer’s memory and hard disk to become full. Usually this virus detects computers connected to the internet and email.
Trojan
Trojan viruses are generally the same as worms, which attack computers connected to the internet network and via email received by users. This type of computer virus will control and even steal data on the computer and will send it to the trojan maker itself. The goal is of course to get information from the target, such as passwords and system logs.
Backdoor
Almost the same as a trojan. However, Backdoor usually resembles a file just fine. For example games. However, the term backdoor is more often used in the context of hacking. In hacking, a backdoor is a secret portal used by hackers and intelligence agencies to gain unauthorized access to a software, website, or computer system. Because, Backdoor in a software or computer system is an undocumented portal. This portal allows administrators to log into the system for troubleshooting or maintenance. So that the most dangerous thing about this virus is the theft of data through this backdoor.

For that, we need to be vigilant if our computer is attacked by a Rootkit.

Metamorphic Virus
Viruses that change their own coding to make them harder to detect.
