11 Infectious Malware Types to Watch Out for in 2021

Did you know that 560,000 new pieces of malware are discovered every day across the globe?

There are many different malware types out there, and each of them is harmful to your computer as well as your identity. Malware works by enabling unauthorized access to your computer or device for purposes like theft or espionage.

Malware is commonly spread through phishing emails as well as malicious attachments that lead to downloading a host file that has a computer virus. The best way to stop them is by being aware of them and the way that they work.

Continue reading to learn more about the 11 infectious malware types to watch out for in 2021.

1. Ransomware

Ransomeware is a type of software that uses encryption to block a computer user or owner from accessing their data until a ransom gets paid. This software keeps the victim, whether a person or a company, from being able to operate until that money gets sent to the perpetrator.

Unfortunately, even if you pay the ransom there is no guarantee that they’ll allow you access to your data again.

2. Fileless Malware

Fileless malware works in a very similar fashion to a trojan virus or computer worm. It doesn’t install any software onto your computer. Instead, it makes changes to native operating system files. This tricks your computer into thinking the changes are legitimate.

If you have an antivirus program, fileless malware can slip past it since it makes small changes to files that belong on your computer. Due to the stealth of these attacks, they are much more successful than other types of viruses.

3. Spyware

Spyware does exactly what its name implies. It collects information about a user’s activity stealthily. It works without the user even knowing that it is collecting all of their data and information. 

This information includes usernames, passwords, PINs, and even payment information. Spyware isn’t exclusive to just desktop computers, either. It is also a threat on mobile devices that you need to take seriously.

4. Adware

Similar to spyware, adware tracks a user’s web browsing activities and decides which ads should get served to you based on that data. Adware is similar to fileless malware because it doesn’t install anything on your computer.

The biggest threat of adware is the continued erosion of your privacy. This data gets collected and used to build a profile about you. It is then sold to marketers for them to market their products to you without your consent.

5. Trojan

A trojan virus is tricky because it disguises itself as a desirable type of software but once it has been downloaded it takes control of your systems.

The most common places for trojans to hide are in games and apps. Some have even been found in fake patches for software. 

6. Worms

Worms work by targeting vulnerable parts of your operating systems. They install themselves into your networks and find access through multiple points. They’ll find backdoors into software and other parts of your computer.

The most common reasons for the use of worms are to steal sensitive data that belongs to you, as well as to attempt ransomware attacks.

7. Virus

A computer virus is a simple piece of computer code that finds a way into an application on your computer. Once that app is accessed the code executes its function. 

Viruses are primarily used to steal sensitive information as well as to launch ransomware attacks on the user. They are completely dependent on a host file or host application in order to be effective.

While viruses may seem similar to trojans, they can’t work or reproduce unless the app they’re hiding in is run. Trojans work by requiring the user to download them and grant them access to their data and information. If you need a virus removed from your computer this is the perfect place to get help.

8. Rootkits

Rootkits are one of the scariest malware types because it gives the malicious actor remote access and control of your computer with full capabilities. Rootkits are found in applications, kernels, and firmware. 

The most common way for rootkits to spread is through phishing emails and malicious attachments as well as malicious downloads. On top of that, Rootkits can conceal other types of malware within them.

9. Keyloggers

This type of spyware works by monitoring your activity on your computer. Keyloggers have a legitimate use for monitoring employee activity at a corporation.

They can also be used with malicious intent. They are commonly used to steal sensitive data like your passwords and your banking or payment information. Keyloggers get inserted into a computer through phishing, attachments, as well as social engineering.

10. Botnets

Bots are automated applications that are built to perform tasks on your computer. Like keyloggers, they have a legitimate use but malicious actors have turned them into something more sinister.

Bots have the ability to connect to a central server and form a network as a means of coordinating flood attacks. These attacks have involved over two million computers in the past and are capable of expanding quickly.

11. Mobile Malware

Malware has made an increased effort to target mobile devices in recent years, with 2019 seeing a 50 percent increase in mobile malware attacks. Mobile malware comes in all different shapes and forms.

Common types of mobile malware are trojans and ransomware and they come as a result of malicious downloads and phishing. They are especially troublesome for smartphones that are jailbroken since they’re no longer protected by the phone’s operating system protection software.
