They can use that personal data for any illegal activities, such as identity theft, and can lead to other phishing scams as well. One thing about spyware is that it is hard to detect it on your computer. As a result, it is difficult for a user to identify if their computer has this malware or not.

As per stats, intruders carried out more than 5.6 billion malware attacks globally in 2020. Although the figure is down from 2019, which saw more than 9.9 billion malware attacks due to improved cyber security measures, the high number of malware attacks are still concerning.

So, if you are wondering about the common threats of spyware and the protection measures you can take against it, then you have come to the right place. We will cover everything in this article regarding spyware, its types, how cyber security measures can help stop it, how do you remove one. So, without further ado, let's get right into it.

What is Spyware?

Let's start by knowing more about what spyware is all about. It is a kind of malicious software that installs on your computer device without your authorization. The malware then spies on your device to gain access to sensitive personal information without your knowledge.

The spyware aims to gather all your personal information and then send it to external firms for advertising purposes. Therefore, any software that downloads on your device without your authorization is spyware. The main reason many consider spyware as a threat is because of its usage by many people.

Spyware gives others access to your personal information. As a result, they can use your confidential details in any way they want, particularly for illegal activities. It can keep an eye on your login credentials and look at the sensitive information on your computer. Hackers use spyware to gain bank account details and obtain information regarding your credit card.

In addition, many people can use it for stalking. The case of Stalkerware is a primary example of how spyware helps keep an eye on another person’s activity. It allows users to keep track of the location of another person, eavesdrop on their calls, access their emails, and much more.

The Federal Trade Commission is finalizing orders to ban the Stalkerware provider due to its usage. Detecting spyware can be a challenging task. Since the spyware does not appear on the screen, you cannot find it.

However, few indications give you hints that your device has spyware. It includes:

  • Slowing down of you processor speed

  • Affect on the network connection

  • Impact on the data usage and the battery life if the spyware is in your cell phone

History of Spyware

The exact date to know when spyware came into existence is difficult. Some references tell the term was common during the mid-1990s in the Usenet discussions. By the start of the 21st century, many cyber security companies started using the term more frequently, just as we use it today.

They picked up some software that accesses the computer system without the user's permission, and its main purpose is to spy the activities taking place on the computer. Spyware has been a top issue for many individuals and users since the start of the century.

As the world rapidly increased its reliance on digitalization, cybercriminals used spyware to access the user's private information. Today, spyware is a massive problem for Windows operating system. Since it is the most prevalent operating system, many attackers target it.

But, over the years, spyware attackers are now targeting Apple applications and platforms. The growing usage of Apple is why many spyware developers are now targeting it. And not just computers but smart phone devices are now on the radar of cybercriminals.

How does Spyware Work?

The malicious software can get into your device in several ways without your knowledge. It can either enter via a:

  • Document attachment

  • Malicious website

  • App install package

The least damage that the spyware can cause is in a form of an application that only runs when you start the device and continues to run till your shut it down. You will feel a slow processor and notice more pop-up ads coming up. As a result, it can impact the browser's speed, and ultimately you won't be able to use it.

Spyware is also capable of changing the homepage of the browser. It can always ensure that the homepage opens to an advertisement. It can also reroute searches along with manipulating the results, essentially making the search engine worthless.

Furthermore, spyware might alter the computer's dynamic data catalogs, which are essential to access the internet, leading to connectivity issues that are not easy to diagnose. And this is just the least of the damage the spyware can cause.

The worst damage that the malware will do is keeping an eye on the browsing history and your confidential data. It will track and monitor all your financial details and other records. This information will be either going to a third party or for other illegal purposes.

Spyware usually gathers your information through key loggers or taking snapshots of your screen from time to time. Additionally, it can change your computer's firewall settings and reconfigure them to do more harm to your device. Advanced malware can detect any attempts to remove them from the device and try to block it.

Types of Spyware

Spyware is not just in a single type that can enter your device. It has many different forms to access your data in multiple ways. Here are some common types of spyware that you can find.

Keyboard Loggers Keyboard loggers are common system monitors that not only the cybercriminals use, but:

  • Parents for monitoring their child's search history and internet usage

  • Employers to check on their employees for any data or privacy breaches

  • Individuals to track the usage of their devices for any activity that they did not authorize of

  • Law enforcement or government agencies for cyber security and tracking any incidents relating to computer usage

The keyboard loggers can be in two forms: Hardware and Software. Hardware keyboard loggers are in the form of Universal Serial Bus flash drives that are a connector between the keyboard and the device. They track down all the activity happening through the keyboard.

On the other hand, software key loggers don't require any physical connectors. The spyware downloads itself to your computer unbeknownst to you and then tracks all the activity happening on the monitor. They can either be in the form of software or through a remote access called Trojan.


The spyware that many cybercriminals use to access your personal information is Trojans. It is a type of spyware program which portrays itself as an official program. Trojans can be installed directly on your computer without your knowledge.

This malware gives remote access to the other user who can delete files, encrypt them or lock you out of these files, or enforce any other spyware activities to get their hands on your personal information. Banking Trojans are a common Trojan that many hackers use.

These Trojans target financial institutions such as brokerage firms, banks, etc., to reap important business information from them. They can transmit the information to another server, alter the transactions, and use other ways that the user and the host web application cannot see.

Password Stealers These are programs or apps that take out the credentials from the computers. This form of spyware can harvest passwords from your browser or your system. The attacker can keep it on your computer or move it to a different server to retrieve it later.

Have never given PC security much…

Have never given PC security much thought. Usually just download a free one! The last couple of years the free ones have annoyed me so much with their constant advertisements for themselves etc, that I removed them from my computer. It was great to discover Guardio, It has been a relief having it with so much going on in the world and so many nasty people scamming innocent people. It's great when I think I want to click on a site and a Guardio message come up saying they believe it is a dangerous site so I don't go there.
