You can create it only by using the Notepad application and a few coding commands in it.
As the name implies, a virus means to bring and have a bad impact. For the computer itself, the virus will reproduce itself to fill up the hard disk memory and make the RAM smaller. Not only that, if the virus is allowed to continue in the computer system, it will damage the entire system and devices. More than that, the virus can also steal data, delete files and infect other devices on the network. However, how does this virus appear, what are the types of dangerous computer viruses and how to deal with them?
Factors for the emergence of computer viruses Before discussing further about types of computer viruses, it’s a good idea to know in advance what are the factors that cause viruses to appear. Therefore, below are five things that cause computer viruses to emerge, namely:
Computer Not Protected Anti Virus
The first factor that causes a virus to appear is the absence of an anti-virus that protects your computer. In fact, every computer must have anti-virus so that it is protected from various kinds of virus attacks. Anti virus is now available in several sizes, from small to large. To get it, you don’t need to pay a fee, because it’s available for free. You only need to download and install it on your computer. Not only that, you also have to always check whether the anti-virus is updating or not. If there is an update, then let the anti-virus update the system. The reason is, the anti virus will strengthen its security to fight new viruses that might attack your computer.
Visiting Suspicious Sites
The next factor is that you may have visited suspicious sites. The meaning of suspicious here is sites that contain illegal content, such as porn, gambling and so on. Such suspicious sites usually remain available only to reap the benefits of their visitors. Because, when you watch and download content from these sites, usually the content is accompanied by a trojan-type computer virus. Where, the trojan virus is one of the most dangerous viruses in the world. For that, as much as possible avoid visiting other suspicious sites of the same kind.
Suppress Phishing E-mail
Phishing e-mail is one of the usual actions to trap someone so that their device is infected with a virus. The trick is to send e-mails that contain dangerous attachments. The purpose of phishing e-mail itself is to provoke someone’s emotions to suppress and open the malicious attachment. In fact, there are several psychological techniques commonly used by fraudsters, but the ones commonly used include e-mail, social media to fake messages. Because, most people and easily fooled through these three techniques. Therefore, you should be careful when opening messages, whether on social media, e-mail or messages.
Downloading any Application or Software
The fourth factor that causes viruses on computers is carelessly downloading some applications or software on the internet. The reason is, if you download on a site with no clear source, it is feared that the application or software you download has been exposed to pirated viruses. Well, if that is the case and you have already installed an application or software that has been exposed to a pirated virus, then automatically your device has also been infected with a virus. Therefore, before downloading an application or software, it’s a good idea to know first the site that provides official and clean from viruses or not. That way, at least you minimize the possibility of your device being exposed to pirated viruses and other dangerous viruses.
Using Wi-Fi without a password
The last factor is the use of Wi-Fi which has no password or password. Maybe some of you feel happy if you find Wi-Fi connections in public places that are not locked by a password. But in fact, this internet connection will actually endanger your computer if used. Because, an internet connection that is not locked by a password will be very vulnerable to being exposed to viruses. Therefore, we recommend that you use an anti-virus and perform a malware or virus scan at least once a week, even if you are not using your computer.
