What is a Computer Virus?
Computer viruses are simply software created with malicious intent. This software cannot be created by any user, but by those with programming knowledge. Also, a computer virus aims to damage some functionality of your system or even the hardware of one or more computers. This kind of software can replicate itself. This means that once they are released on the web, their creators no longer have control over them. Furthermore, they use documents or files to reproduce and spread. Some symptoms of viruses are:
- Multiple popup windows
- Sudden changes on the home page
- Emails of mass messages without your authorization
- Damage to your computer hardware
- Lower system performance
- Unknown programs that start automatically
- Strange activities like a password change
Viruses generally seek to destroy data or corrupt systems, among many other common damages. Once the virus has entered your system it can remain inactive. This passive state is maintained until the code that the virus has incorporated is executed. Today there are a lot of ways that a virus can spread. Furthermore, it can not only attack computers but also other electronic devices. Therefore, your smartphone or tablet is also vulnerable if suspicious files are downloaded.
So, avoiding all kinds of contact with viruses turns out to be very important. Please note that once a virus enters your system, it is very difficult to remove it. Of course, it will be difficult if you do not have any type of antivirus or protection software on your system.

As we have seen, some computer viruses can be common and others – novel. In the same way, some are much more harmful than others. However, all of them generate some type of damage or inconvenience in your system. See some more common viruses and the effects they produce:
1. The resident virus: This type of virus has its name because it is installed in your RAM. After that, it will be an obstacle to the normal operations of your system. Besides, they can be combined with some antivirus software files.
2. The multiparty virus: It is software that will try to affect your entire system. Its way of propagation is by performing actions that are not authorized. So it will affect different programs, folders, and even your operating system.
3. Direct-acting viruses: These types of viruses generally target .exe files directly, and do so because they replicate and infect other files. Luckily, due to its operation, it is a virus that is detected and removed very easily.
4. Browser hijacker virus: This virus is another one that can be easily detected. It aims to direct you to malicious websites, once your browser is infected.
5. Overwriting virus: This virus gets its name from the fact that it tries to infect programs, files, and folders by re-writing its content.
6. Web Script Virus: This virus is intended to camouflage itself within the encoding of videos, images, advertisements, links, and site code. Furthermore, a system can become infected if the user downloads some malicious software or files, or visits undesirable websites.
7. File infecting virus: This type of virus seeks to slow down different programs, and damages every file on the system that the user runs.
8. Network virus: This is a very common virus that travels over network connections. Additionally, it seeks to replicate using shared resources.
9. The boot sector virus: This is one of the easiest viruses to avoid. They are usually hidden in an email within an attachment, or on a USB drive. If this virus is activated it could infect the master boot record of the entire system, which of course causes damage.
