Previously we have discussed the kinds of viruses that exist on computers. Now we will discuss, how a virus can enter our computer. Consciously or not, three things can cause a virus to infect a computer. The first is because of the habits of computer users and the second is because of an unprotected or protected but weak network security system and the third option is a hacker who deliberately hacks into our computer or network.
Of the three things, it turns out that the way computer virus infection can be in various ways. The following are 6 reviews about the most common causes of computer virus infection:
Has no anti-virus at all
A security tool and the latest antivirus program on the computer is very important, especially with automatic scanning capabilities to protect your computer from virus infection. If your computer already has an anti-virus, you need to pay attention to the anti-virus update.
There are many antivirus products available from free to paid ones, but we must be smart in choosing the antivirus that suits our needs. Especially for the enterprise-class, we recommend using Cylance Protect Cat as the anti-virus of choice.

Visiting suspicious or untrusted sites
Suspicious or untrusted sites, namely sites that contain illegal content such as pirated sites, pornographic sites, or gambling sites, and so on.
The content has usually been infiltrated by virus code such as a trojan virus. This virus can be categorized as one of the most dangerous computer viruses in the world.
Besides, you must always pay attention to the green lock (https) in the search engine URL search field. Sites without green locks are potentially dangerous because they cause viruses or malware infections on computers. For that, avoid visiting sites like this. If necessary, use preventive measures by using the Web Cat license from LanScope Cat. Which can function to block sites that you want to block so that computer security can be maintained and your employee productivity remains well.
Suppress Phishing E-mail
The simplest way to do this phishing email is they send an email with a subject that catches the attention of the reader accompanied by an attachment in the form of a document.
The purpose of phishing e-mails is to provoke someone’s motions to suppress and open the malicious attachment. The attachment is usually a virus or malware that is intentionally sent by the perpetrator which will be active when the reader clicks or downloads the attachment.
There are several psychological techniques commonly used by the perpetrator, but the ones commonly used include e-mail, social media to fake messages.
Because most people and gullible through these three techniques. Therefore, you should be careful and suspicious when opening messages, whether on social media, e-mails, or messages via cellphones with suspicious subjects or attachments. So, ignore the message.
As a precautionary measure, you should use security for email so that phishing emails or various kinds of spam that are not important and dangerous can be rejected by the system. We recommend that you use Secure MX. Secure MX is a SaaS that functions specifically to keep your email safe.
Downloading any Application or Software
The fourth factor that causes viruses on computers is carelessly downloading some applications or software on the internet whose source is unclear. It is feared that applications or software that have been downloaded will be exposed to pirated viruses or are prone to viruses.
Therefore, before downloading an application or software, make sure to download it on the official site and never install pirated applications or software. This is an early prevention effort, so that our computers are not attacked by viruses or dangerous malware. As a solution for enterprises by using the Log Cat license from the LanScope Cat, it will be easier for enterprises to find out which sites are accessed by their employees even though they are working on a Work from Home system.
Using Wi-Fi without a password
The fifth factor is the use of Wi-Fi that has no password or password. Currently, many internet connections are easy to find. 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, a public Wi-Fi connection that is not locked by a password will be very dangerous for our computers if used. Because indirectly we make it easy for hackers to access our computers through these public networks so they are vulnerable to various viruses or malware.
Therefore, you should use Cylance Protect Cat anti-virus as a preventative measure to fight malware or viruses and use a trusted Wi-Fi network such as an office LAN or personal Wi-Fi at home because the security will be more secure.

An office LAN network that does not have a firewall
The last factor, namely LAN networks that do not have a firewall will also be susceptible to viruses or malware. The firewall itself is a protective computer network system and other devices that are useful for protecting threats or harmful content from outside computers.
Also, it turns out that a firewall has other functions besides being a network security post that checks, filters, limits, or rejects all activities that occur on the computer and works automatically according to the criteria of the source computer’s IP address. Among them, namely, as a controller and supervisor of the flow of data packets, recording all activities of computer users, and preventing information from being leaked.
