Malware encompasses all types of malicious software, including viruses, and cybercriminals use it for many reasons. This is why everyone should know about it. Cybercriminals are able to use information that an individual is communicating with over the Internet to infect their devices and trick them into downloading malicious software, thereby causing the user to open a malicious attachment and damage his or her machine.
As we have already mentioned, malware is important to learn how to avoid. Moreover, it is important to know how to detect it when it gets on your device. Generally, it is not easy to detect it. It is like a virus that lies dormant in your computer that can take control of your device or spy on your data.
Computer Malware can be distributed through any of the following means:
- Direct Download from a third party site
- Download of a free plug-in from the Internet
- Malicious attachments
- Web-based files
Now that we know a few basics of computer malware, let us continue the discussion. Malware, malware databases and antivirus are tools that can be used to analyze software to spot and remove malware and there are also services as Fortinet which can also help with this. However, the analysis of each program cannot guarantee that all the malware has been eliminated.
Most popular antivirus products contain many different types of malware. Currently, there are no established categories for antivirus. This is because there are no standards for analyzing malware. Every antivirus product must fulfill the requirements of its manufacturer, which are to do with detection capability. This may result in, among other things, the creation of many false positives, because a person cannot be told which type of malware he or she should pay attention to. This is why, if we choose a good antivirus program, we have to find a program that is specifically designed for analyzing computer malware.
According to the malware research, there are four main types of computer malware:
- A Trojan
- Malicious Program
Trojan is a self-replicating program, which means that it can exist on any type of computer system.For instance, Windows will become infected with the Trojan when someone clicks on an infected link in an email.
The Trojan is carried as a link or files on a.exe file. This is one of the reasons why attackers try to spread the Trojan. As in the case of other viruses, the Trojan infects itself and spreads to other systems. On a personal computer, it might infect a user’s documents and documents on the hard disk. This creates a slow-down and, in some cases, renders the computer unusable.
A Trojan can perform several tasks. It can:
- Steal information from the system
- Download and install malicious applications
- Open local and remote files and folders
The Trojan downloads itself from a remote website or some other URL. The Trojan uses a number of tricks to escape from detection by current security technologies. For instance, it will open a backdoor that is known as a Man-in-the-Middle attack (also known as a man in the browser). The Trojan, when launched by an attacker, will make itself appear as a legitimate website. If a malicious webpage is opened, the Trojan will install its software and begin downloading its code. On a good antivirus program, the Trojan will never penetrate all layers of protection. It will either be blocked at the beginning or, after download, will fail.
