About the Types of Malware
Malicious software written in the short form is a type of malware. They are computer programs designed to infect a host computer without the consent of the knowledge of the user.
“Each type of malware acts differently when taking the computer down.”
Some types of malware cause the system to crash, whereas other types go about spying on the users computer activity. Never the less, these are undesirable programs as it often leads to the stealing of information and the compromise of security.
Different Types of Malware
Depending on the mode of infection as well as how the malicious software program acts on the computer, the type of malware can be classified into different varieties. They have been discussed in brief below.
Types of Viruses
It is a mistake to label all malware as a virus. A virus infects a system and modifies the host file such that each time the file is executed, the virus gets initiated. At present, with the different types of malware around, viruses have become less frequent and comprise just about 10% of the infections at any time.
The worst part of viruses is that they are residents in other computer files, and this makes it hard to clean them up. Most anti-virus programs would, at best, quarantine the virus and never get to eradicate it from the system completely. Attempts to altogether remove the virus might…
“…in most instances, damage the system file that is required to run the host computer. “
Types of Computer Worms
A worm is a self-replicating file that is usually downloaded with email attachments. Quite unlike a virus, the worm does not need to be initiated to action. It tends to infect more than a single file and spread fast within networked systems. With a worm infection, it is possible that entire networks can be taken down in quickly.
Anti-virus programs are rather ineffective in the handling of the worms as they keep replicating at a rather rapid pace once an infection takes place. Often it changes the host file so quickly that the anti-virus programs cannot react fast enough to counter its actions.
Types of Trojans
Trojans are programs that trick the user into initializing the program. Most of the time, the computer user gets a message that there has been an infection, and just the right actions have to be taken to neutralize it or to remove the infection. It is this very action taken that initializes the Trojan to be installed in the system.
It must be said that an alert computer user can quickly neutralize the action of the Trojan. The best remedy is not to respond to sudden uninitiated messages that claim to fight infections and the likes. Trojans are very common in use as it is easy and does not require much know how to write one such bit of code. However, they always need the action of the host computer user to be initiated, which is why they can be quickly neutralized as well.
Types of Ransomware
A version of the Trojan that infects files and encrypts the same. It then demands payment, typically in cryptocurrencies, to render the system safe again. The most damaging aspect of these types of infections is that they tend to lock down a computer through encryption of the files. It leads to a complete inability to use the computer in any manner.
There is no guarantee that once the ransom is paid that the computer would be free of the menace. Often instances were that the infected networks are not released from the attack even after sums of money are paid to the initiator of the infections.
Types of Adware
Adware is some of the most harmless types of malware infections. When a computer user happens to notice unwanted pop-up websites being loaded; most probably as an advertisement for products and services. Then it is a good sign that the computer has been infected with adware. The good thing about adware is that it can be neutralized by identifying the problem file within the windows system and removing or deleting the file from the system.
As computing systems become much more complicated than ever before, a malware infection tends to have a still more devastating effect. Simple anti-virus programs have severe restrictions in dealing with malware most of the time, and it takes specialized programs to remove infections from systems. Damage caused by the malware can be limited by being more vigilant to unusual messages that ask for permission to install applications that are made, especially unsolicited messages.
