Spyware is unwanted software that makes its way onto your computer, often without you even realizing it, to track, monitor and get hold of your personal information.
These infections can integrate into your operating system to monitor keystrokes, edit your settings and decrease your device performance, so that it can capture sensitive data such as your login details, email and browsing history, and credit card details.
Studies show that nearly 90% of U.S. home computers have contracted a spyware infection at some time. In most cases, this can be nothing more than an ongoing annoyance. But in other cases, the effects of spyware infections can be disastrous, causing heavy financial burdens and ongoing stress.
So how do you go about identifying, preventing and protecting yourself from spyware?

What is Spyware?
Spyware is a type of computer infection that allows hackers access to your personal data. It can attack PCs, Macs, iOS and Android devices. Software of this kind has many uses, some of which are legal, such as:
- Monitoring company computers to ensure that nobody is spreading sensitive information
- User-consented tracking for targeted advertising
- Parental control software to track children’s online activity
- Website cookies to customize your browsing experience
Unfortunately, at least 40% of spyware falls into a more malicious category. It’s regularly used by criminals to steal personal information from their victims for financial gain. Common spyware activity includes:
- Obtaining your bank details to gain direct access to your money
- Intercepting personal information, such as contacts, passwords, and web activity
- Collecting enough personal data to steal your identity
- Recording your browsing habits to send you personalized ads
Spyware has even been known to record instant messages and Skype calls, hijack your webcam, install keyloggers and take photos and videos.
Spotting an Infection
Spyware can be a particularly tricky infection to spot as it can change your security settings to avoid detection. Keep an eye out for any of the following red flags that may signal an infection:
- Pop-up ads suddenly appearing all over your computer
- Considerably slow device speed
- Your computer begins to freeze or crash more than normal
- There is a drastic increase in CPU usage
- Your default browser page changes and redirects to another site
- Your antivirus or security software begins to malfunction
- An increase in auto-redirects when online
While each of these factors individually may not mean anything too serious, experiencing several is a sure sign of a problem.
How Can you Get Infected with Spyware?
Spyware can arrive on your computer via many channels. However, the most common source is piggybacking spyware – basically when a program secretly installs itself alongside another (often more trusted) program you’ve chosen to download.
We’re all guilty of downloading free games or apps to do minor jobs for us online. But if these aren’t properly vetted and reviewed, it can cause an infection.
Other ways to contract spyware include:
- Clicking on infected ads or pop-ups
- Visiting infected websites or domains
- Downloading software from unreliable sources
- Opening email attachments from unknown senders
- Downloading media from torrenting platforms
How to Prevent Spyware
As the nature of malware is continually developing, there is no foolproof tactic to keep you safe indefinitely. The best defense of spyware is, of course, not to download it in the first place. So you’ll need to change many of your personal habits and be extra vigilant about what you’re clicking on online.
Follow these rules to reduce the chance of a spyware attack:
Use an antivirus security suite with an anti-spyware tool
If you use a good antivirus, then you’ll already be one step ahead. A decent security suite with a dedicated anti-spyware tool will stop spyware before it gets installed on your computer.
Opt for an antivirus that provides real-time monitoring, specific detection, and removal options for spyware, and make sure that it is regularly updated to combat the very latest spyware threats.
While it’s preferable to stay ahead of spyware and avoid disaster, sometimes infection will happen. Don’t panic – it can be resolved easily if you act fast; this is where an antivirus comes in handy! See our picks for the best antiviruses on the market.
Never click on unsolicited ads
A huge percentage of online ads contain spyware. Avoid clicking on any to reduce the risk of infection. If you see something you’re interested in buying, do a search for the item/brand instead and purchase it directly from the official or a reputable website.
Read reviews before downloading software
Research any apps you’re interested in carefully before you download any and, wherever possible, only download from the official website. Most trusted products will come with reviews so always check these first to ensure you’re dealing with a trustworthy product.
Adjust your browser security settings
Browsers contain a range of security settings that allow you to dictate how your data is used. You can choose to stop cookies completely, authorize them for specific sites, or set allowances to only share some information. Monitor your security settings regularly so you can be aware of any changes.
Engage in smart browsing
Never open an email attachment or message from someone you don’t know; if you see a suspicious link from a friend, confirm that it is actually from them before you click on it. Any pop-up claiming you’ve won $1,000,000 or an iPad should never be trusted.
Avoid accidentally clicking on pop-ups when closing them
Many infected ads purposefully make it difficult to close them. They might use a fraudulent ‘X’ in their design, which tricks you into clicking instead of closing.
Be vigilant when shutting down pop-ups to avoid opening the link by mistake. Instead, press Alt + F4 or be careful to select the correct “X” on the corner of the pop-up alert to close the window.
Use a firewall
Firewalls filter the network and are a great defense for blocking risky websites, therefore making it more difficult for spyware to get onto your computer. Take a look at these antiviruses that come with firewall protection.
Educate your family about the risks
If you have young children, it’s essential they understand the risks of spyware. When surveyed, 69% of computers in homes with children under the age of 18 had spyware. Young people tend to be less risk-aware, so teach how to detect dodgy links.
How to Remove Spyware
If you suspect you’ve been infected by spyware then the first step is to turn off your internet connection. The infection works by sending your data back via the web, so this puts an immediate stop to the process. Once you’ve done this, you have two options:
Remove it Using Software
- Use a top-quality antivirus to perform a full system scan
- If you already know where the infection is located, you can opt for a custom scan to target a specific area
- Once you have identified the problem, use an anti-spyware tool to automatically quarantine and delete the malware
Remove it Manually
If you know the source of the problem, you can remove it by hand. Open up your application menu to view all of the active programs. Identify the app that is causing the problem, right click, and choose to “uninstall” and “delete” the program.
Be aware that manual removal does come with its risks. If you choose the wrong program, such as an operating system program, you could make your computer inoperable. Always select the option to hide system programs and do a search for the name online before deleting anything completely.
The Best Antivirus to Protect you from Spyware
An antivirus is a great way to stop spyware from getting hold of your computer and stealing your information. While even a free security solution is better than nothing, it’s best to choose one that provides real-time monitoring, specific detection, and removal options for spyware so you can be sure you’re 100% protected.

Prevent Spyware & Protect your Data
As we’ve mentioned above, the very best protection against spyware is not letting it get onto your device in the first place. But quite often, its already too late for prevention and you need to focus instead on removing the threat from your computer either manually or by using software.
Either way, now that you’re aware of the threats of spyware, the solution is the same: follow these steps to prevent an infection in the future and, if you are infected, remove it quickly and efficiently using a good security solution.
