7 Types of Malware Attacks and How to Prevent Them

What is malware? Malware is any malicious code with the intent to cause harm.

This could be anything from damaging systems to stealing sensitive data. Any gadget such as servers, PCs, smartphones, tablets, among others, are all at risk.

Malware can corrupt and take charge of all the systems in these gadgets. This makes malware a threat to businesses both from a productivity and a financial perspective.

In addition, it can compromise a company’s systems to the extent of ceasing operations entirely.

Malware attacks are the first step to taking over your PC.

However, you can use an antivirus or VPN to protect your device. You can also use VPN to watch US Netflix as well as other blocked streaming services.

A VPN won’t necessarily protect your device in case of an attack. However, it will seal all the loopholes that hackers use to access systems by encrypting all your data.

Malware can also spread to other systems in what may initially have started as a tiny breach into a network.

It does this by embedding harmful code in any device that it comes into contact with. Let’s look at some of the types of malware that affect our devices.

Some of The Types of Malware Attacks Today Include:

Virus

Viruses are malicious programs that embed themselves in computers, and they can change files, replicate in various folders, and spread to other gadgets within your network.

How Can You Prevent This?

  • Ensure your computer applications are up-to-date
  • Install antivirus software on all your devices
  • Check for any weaknesses in your system

Ransomware

Ransomware is malware that scrambles your system files using a cipher only known to the hacker who sent it.

The hacker will proceed to ask for a ransom, or you risk not getting back any of your documents.

How Can You Prevent This?

  • Ensure data backed up safely
  • Beware of dubious emails from unknown sources
  • Use cloud storage that supports MFA (multi-factor authentication)

Spyware

As the name suggests, spyware is intended to spy on the target and amass credentials such as bank details, transaction details, social security numbers, browser history, among other things.

How Can You Prevent This?

  • Refrain from clicking dubious links or pop-ups
  • Install antivirus software on your device
  • Whitelist apps that are authorized to run on your device

Worm

A worm is quite similar to a virus because it’s self-replicating, and it can get to other devices on the same network.

This makes worms much more dangerous than viruses because they spread faster without being detected.

How Can You Prevent This?

  • Set up a firewall to limit your network traffic
  • Beware of dubious emails from unknown sources
  • Ensure your PC operating system and apps are all up-to-date

Trojans

Trojans are some of the most popular kinds of malware. Hackers will disguise Trojans as attractive gifts such as special coupons, discounts, gift cards, among others.

The hacker will make it seem as if these gifts are from a vendor you usually purchase from so that you won’t suspect any foul play.

Rootkits

A rootkit is a backdoor program that enables a hacker to take over a device or system without the owner’s knowledge.

Such a hack can result in complete control of the hacked system.

How Can You Prevent This?

  • Get rid of the rootkit and build the compromised system again from scratch
  • Some antivirus apps can detect rootkits, but they are hard to clean from a device

Adware

It is a kind of malware designed to automatically send ads to people in order to generate profits for its developer.

Adware is similar to spyware, and it appears in the form of ads embedded in computer software or a pop-up on a webpage.

How Can You Prevent This?

  • Be careful about the web pages you visit
  • Refrain from clicking on pop-ups or ads
  • Ensure your PC operating system and apps are all up-to-date

Final Thought

To sum it all up, if your company’s systems and servers are hacked and malware installed, it can be catastrophic to your productivity and profits.

However, if you follow some of the measures illustrated above, you can mitigate most malware attacks and keep your business afloat.
