Spyware Definition

So, what is spyware?

Spyware is unwanted or malicious software that attacks a computer, stealing sensitive information and crucial data. It is a type of malware entity that gathers a victim’s personal information and sends it to third parties, advertisers, or data firms.

Though spyware has many uses, it’s been widely used in fraudulent activities, such as stealing bank and credit card information and identity theft.

Common Types of Spyware

There are four common types of spyware. Each of them uses a different tactic to track its victim.

1. Adware

This is a type of spyware that tracks a victim’s downloads and browser history. Its purpose is to check what products and services you are interested in. Once the adware has gotten the information it needs, it will display ads for related products, enticing you to make a purchase. Basically, adware is created for marketing purposes.

2. Tracking Cookies

As the name of the spyware suggests, tracking cookies track a victim’s web activities. Although they’re somewhat similar to adware, what makes this spyware different is the information it gathers. Tracking cookies collect download, history, and search information, while adware gathers data about products and services that a victim usually searches for on the web.

3. Trojans

A Trojan is a type of malware that disguises itself as legitimate software, meaning it could appear to be an Adobe Flash Player update, where in truth, it’s actually malware. Often controlled by third-parties, Trojans are commonly used to steal sensitive information, such as credit card details and Social Security numbers.

4. System Monitors

System monitors are a type of spyware that spies on everything you do on your computer. They record keystrokes, check emails and log the websites you visited. More often than not, they disguise themselves as freeware.

How Spyware Attacks Its Victim

Spyware can attack a wide range of devices, such as Android and iOS smartphones and computers running Windows or macOS. However, among all devices, Windows computers are the most vulnerable and susceptible to attacks.
Below are some ways that a Windows computer can become infected with spyware:

  • Accepting pop-up notifications without reading them first
  • Downloading apps and programs from unreliable sources
  • Opening email attachments from anonymous senders
  • Torrenting media, such as games, software, music, and movies

Signs of Spyware

Spyware can be very difficult to detect. But the good news is that even if it’s designed to be deceptive, there are actually signs that tell you that your device has been infected.
It is likely that you have a spyware entity on your computer if you see these signs:

  • Your computer seems unusually slow.
  • Random crashes happen for no reason.
  • Pop-ups show even when you’re offline.
  • Unknown browser extensions are installed.
  • Your browser’s home page has changed.
  • You always get redirected to a website you didn’t request.
  • Your computer keeps notifying you that you’re running out of hard disk space.

It is worth noting, though, that you may not always be able to detect spyware. But if you suspect that it has infected your device already, you can perform spyware removal methods or download anti-spyware tools.

How to Remove Spyware

Do you suspect that a spyware entity has infected your device? What you can do is perform a quick system scan first to clean up your computer. And then, download a spyware removal program. Once you’ve downloaded one, run a quick scan.

This should only take a few minutes. After that, spyware entities can be identified and removed.

You don’t need to shell out all your hard-earned money for an anti-spyware tool. You can find plenty of free spyware removal tools that already offer great protection. You just need to read review sites or seek recommendations.

Now, to give you an idea about the tools that we’re talking about, we’ve listed some of the best spyware removal tools today. While most of them are free, some can be downloaded at a budget-friendly price.

How to Protect Your Device from Spyware

Of course, the best way to protect your computer from spyware attacks and infection is by downloading anti-spyware tools and programs. They will scan your files and data for any signs of threats and prevent spyware entities from being downloaded in the first place.
Aside from using anti-spyware programs, here are other ways to protect your computer from threats on the web:

1. Use a VPN

A VPN may not prevent spyware from being downloaded onto your computer, but it can hide your real location and keep your online activities from being monitored and tracked. In some cases, VPNs also have ad-blocking and anti-malware features that you can take advantage of.

2. Avoid opening emails from unknown senders

Unsolicited emails are among the most common ways to spread malware entities. To avoid downloading spyware, do not open emails, especially those that contain attachments, from suspicious senders.

3. Use a secure web browser

In case you didn’t know, there are other web browsers out there aside from Google Chrome and Safari. Internet Explorer is one. However, the latter option is known to be vulnerable to cyber threats like spyware. As much as possible, avoid using insecure web browsers to ensure browsing security.

4. Download files from reputable sources

If you are downloading software, applications, or files, make sure they’re from secure and trusted sources. This preventive measure goes a long way toward keeping you from downloading spyware by accident.

5. Never click on suspicious pop-ups and links

Often, clicking on a pop-up ad is more than enough to grant spyware access to your computer. To make sure you are not clicking on anything suspicious, hover your mouse over the link first. And then, check the URL where it’ll be taking you. If it’s really an ad that you are interested in, make sure it will take you to the product’s or service’s legitimate website.


Spyware nowadays is becoming more and more difficult to detect. However, if you practice responsible and secure online browsing, you should be safe. A good start would be using reliable spyware removal tools and installing anti-malware software on your computer. When torrenting, connect to a fast and efficient VPN service. As long as you keep these recommendations in mind, then spyware won’t stand a chance.
