What is Malware?
You can say a Malware is a malicious program designed to disrupt the flow of work. Now, some Malware can harm your home computer, while others are there to initiate a DoS in web-based servers.
You can make a list of Different Types Of Malware, such as computer viruses, spyware, trojan, and many more. What is constant is the purpose of engineering such a piece of tech – to harm digital devices or services.

To answer that, you must understand one particular thing – every Malware has a sinister purpose which it carries out without you even notice it. So, when you pay your bills online, it can capture those data and can transmit to others, which is a serious cybercrime.
Different Types Of Malware
One thing that we would like to say that there are hundreds and thousands of Malware types available today that serves several evil purposes. So, it is next to impossible to prepare a list of all Malware.
Instead, we will mention those which is, first of all, common to the world and of course, are causing maximum damage today. So, here they are:
A computer virus is one of the oldest forms of Malware available. The fact that so many anti-virus companies exist today suggests the havoc it can cause. What a virus is an infectious code, and it tends to replicate itself whenever it is active.
One thing that is common in every computer virus is it needs a host program to activate. So, when a virus attached to a .exe file, it spreads the infections to other files, and this process continues.
Worms also share the same traits of a virus. They too replicate themselves to corrupt programs or slows down the system. However, there is a significant difference – unlike a virus that needs a host to work, worms can activate themselves and spread infections on your computer and networks. They are most dangerous when they get an entry to the network computers.
Spyware, as the name indicates, work as a spy for the hackers. They can cause a great deal as they can steal your personal information without you even being noticing.
Spyware works discreetly to collect data, which can be your credit or debit card details or your social network credentials. They are highly dangerous as they won’t slow down your computer or corrupt any program; they will smartly gather info and send it to the hackers.
4. Trojan horse
A trojan horse is a form of Malware that most internet researchers believe that it is causing maximum damage in the digital world. The hackers design them with a particular feature which makes them harder to detect.
It can reside in an image file, a video file, or a doc file. Each trojan can be distinct from one another and can cause damage to any magnitude. Moreover, a trojan horse doesn’t need a host file to activate.
5. Logic Bombs
A logic bomb is one of the deadliest forms of Malware in operation today. Some researchers proved the theory that it can even disrupt the hardware component to malfunction. You see logic bombs are not active all the time.
They only get triggered when the user starts a particular set of actions. This Malware can be catastrophic for servers that must stay in operation 24×7. They have a distinct feature that can overdrive the hardware. As a result, the hardware can overheat and crash down.
Everybody has some data which they don’t want to share or want to protect. What ransomware does is to put the victim in a state of paying a ransom. In most cases, it is for the money. However, there are other forms of blackmailing reports as well.
Either way, if you are the victim, you can’t access your computer or a particular network as they are encrypted. This is the job of the ransomware that a hacker plant to get in possession of your data. So, you don’t have any option apart from paying what the hacker wants.
There are hundreds of organizations that run their illegal operations using others’ computers, without them noticing. So, they can get into your computer without your consent. This is possible with the help of backdoor Malware.
A backdoor can sneak pass your usual authentication and give access to hackers. Now, they could do whatever they want when they want. So, technically you are committing a crime without even noticing.
A rootkit works in conjunction with a backdoor. Let’s face it; every software and OS has its fair share of vulnerabilities. What a rootkit does is to take advantage of those flaws, and tweak the security aspect of the OS. So, that creates a backdoor to take control of your computer or the entire network.
When you set up a password, every security expert suggests an uncommon password, and change them frequently. Unfortunately, 50% of the active computer users do not follow this protocol and hence, pay the price.
Now, keyloggers’ job is simple. They capture all those passwords and IDs that you type on your computer. Of course, they send these data back to the hacker so they can access those digital accounts without your consent.
As mentioned before, there are tons of different types of malware that anyone can suggest. However, we have talked about all the popular ones that we deal with every day. Luckily, there are Malware protection software bundles available today. So, we suggest you should get one and stay vigilant all the time.
