Pop-up ads: we all know they’re annoying, but did you know they can cause real harm? Adware is a program that displays advertisements on your device, usually in the form of pop-ups or banners. Adware can run constant ads all over your device, heavily impacting its performance while making you want to pull your hair out.

Adware is usually bundled with other software or directly downloaded from sketchy websites. It can be a legitimate way for developers to advertise products, but adware is often malicious, serving as a gateway for malware while bombarding victims with ad after ad.

This is extremely frustrating, but don’t panic if you have adware on your device. The solution to adware is actually pretty simple — get a good antivirus. Norton, for example, will easily flush out all the adware on your device. What’s more, its real-time protection will prevent adware and other malware from getting onto your device in the future.

What Is Adware?

Adware is a type of software that automatically displays or downloads advertisements. These can take the form of banner ads or pop-ups that crowd your desktop or webpages. Its main purpose is to generate revenue for its developers by displaying advertisements, but it can often carry hidden threats.

Adware can be legal or illegal, depending on how it works. Legal adware usually comes as part of legitimate programs and applications, where it serves as a revenue source for developers. In such cases, users are typically informed about the adware and might have the option to accept advertisements in exchange for using the software for free.

However, not all adware is so transparent and harmless. Illegal or malicious adware often sneaks onto a user’s device without their knowledge or consent. This category of adware tends to be highly intrusive, displaying an excessive number of advertisements and sometimes altering browser settings (for example, changing your homepage).

Besides the annoyance, this type of adware can degrade system performance and even serve as an entry point for more malicious software like spyware or trojans. Because these threats can be subtle, it can be tough to notice them yourself, which is why having a good antivirus with real-time protection (like Norton) is the only way to know you’re safe.

How to Detect, Remove & Protect Against Adware (Step-by-Step Guide)

Removing adware from your device is a relatively simple process. The hardest part is finding a quality antivirus (but of course, if you follow my recommendations, this part will be easy, too). I’ll be using Norton to show you how to get rid of adware, but the process is almost identical for other premium antiviruses.

Step 1. Install Reliable Antivirus Software

Your first line of defense against adware is a solid antivirus program. I really like Norton because of its wide range of protection tools and flawless threat detection. To install Norton, visit the website, select a plan, and follow the download instructions.

Once your antivirus program has been downloaded, open the application, and the installation wizard will handle the rest. You’ll have to click on a few prompts and customize a few settings, but it’s a pretty intuitive process. Once it’s installed, move on to step 2.

Step 2. Run a Scan

After installation, run a scan to identify any adware already present on your device. With Norton, you have the option to run a quick scan, full scan, or custom scan of specific files. Open Device Security and click on the drop-down menu. From Scans, click on Full Scan, this will let Norton analyze every file on your device for adware.

If your antivirus finds anything, follow the steps to remove it. Norton will tell you the exact threats it finds. You can look these over to make sure it hasn’t accidentally flagged an important file you trust, but Norton virtually never does this. I recommend following Norton’s recommendation and quarantining and removing all threats.

Finally, the antivirus will tell you to restart your device (if it doesn’t, restart your device anyway). Do this because it’s an essential step to ridding your device of adware. After your machine is back on, you might want to run a second scan to be 100% you’re adware-free.

Step 3. Turn On Real-Time Protection

Real-time protection stops you from getting adware in the first place. In Norton, navigate to Device Security, then to the Advanced section, and ensure Auto-Protect is toggled on.

This feature is usually on by default, but it’s always wise to double-check. Each antivirus will call its real-time protection feature something different, but the advice is the same — keep it turned on to stay protected against future adware.

Step 4. Uninstall Any Leftover Applications & Extensions

Adware often comes bundled with legitimate software. Go through your installed applications and uninstall any that you don’t recognize or no longer need. On Windows, use the Start menu to open up the Control Panel and select Uninstall a program. This will open a list of all your programs. Find any suspicious programs or apps that you don’t remember installing and remove them.

You should also find and remove any unwanted browser extensions. It’s common for adware to target browsers as extensions are easy to install but can be hard to detect. The exact steps will vary depending on which browser you use, but the process is generally pretty simple. For example, on Chrome all you have to do is click on the puzzle piece in the top right corner, select Manage extensions, then remove any items that look suspicious. If you don’t remember installing an extension or think the description sounds a bit off, remove it.

Step 5. Install an Ad Blocker

Finally, installing an ad blocker can further protect you from adware (even though an ad blocker alone isn’t enough). Ad blockers prevent many ads from displaying, reducing the risk of accidentally clicking on one that may contain adware or further malware. There are a lot of effective ad blockers out there that you can use to avoid advertisements and trackers altogether.

Common Signs You Have Adware On Your Device

Adware can sometimes be subtle, but certain telltale signs can indicate its presence on your device. Being aware of these signs can help you quickly find and remove adware, protecting your device from further harm. Here are signs to look out for:

• Increased number of ads. If you notice a sudden increase in pop-up ads, banners, or unexpected advertisements on webpages that normally don’t have them, this could be a sign of adware.
• Slower system performance. Adware consumes a lot of system resources. If your device is noticeably slower, especially when browsing the internet, use Norton to check for adware.
• Changed browser settings. If your browser’s homepage, search engine, or default settings have changed without your consent, adware could be responsible.
• New toolbars or extensions. Adware often installs additional toolbars or browser extensions. If you notice unfamiliar add-ons alongside strange advertisements, immediately remove those extensions and scan your device.
• Redirects to unwanted websites. If you’re experiencing frequent, uninitiated redirects to unknown or unwanted websites, adware is likely responsible.
• Decreased internet speed. Like with system performance, adware is notorious for hogging data. If you’ve noticed a steep drop in internet speed, be sure to scan your computer or phone.
• Unwanted pop-up warnings. If you receive frequent and unwanted pop-up warnings or fake security alerts, especially from supposed cybersecurity companies, it might be adware trying to trick you into downloading more malicious software.
• Difficulty in closing ads. Ads that are difficult to close or that open more ads when you try to close them are often caused by adware. This is the telltale sign that a machine has adware and not another type of virus.

If you notice any of these problems, it’s time to scan your system with a reliable antivirus. Norton is my favorite antivirus in 2024 thanks to its flawless scanner, unbeatable real-time protection, and comprehensive security suite. Still, any of our top picks will stop adware from slowing down your device and making you pull your hair out.

How Does Adware Get Onto Your System?

Adware typically infiltrates your system through deceptive means. One common way is through software bundling, where the adware is attached to a legitimate program’s installer. When users install the primary software, they unwittingly install the adware as well. This is why it’s so important to always read through installations carefully and not just mindlessly click through. If you’re asked whether you want to add an unrelated program during an install process, decline.

Clicking on pop-up ads, banners, and suspicious links can trigger an adware installation. Adware can also exploit security vulnerabilities in outdated software to automatically install itself without user interaction. In this case, all you have to do is visit a website, click on an ad, or open a file. Email scams are a common way that people get saddled with adware, too.

Downloading files or apps from untrustworthy sources increases the risk of adware or malware infection. Make sure that your download is from a legitimate source and that the file is safe. The trickiest adware poses as legitimate applications, manipulating users into installing it. Make sure you verify the website or publisher before installing their product.

What Does Adware Do to Your Device?

Once adware has made its way onto your device, it can create a range of issues. The most noticeable effect is a flood of advertisements. These ads can take the form of pop-ups, banners, intrusive browser extensions, or even changes in your browser settings to display more ads. These ads can be incredibly hard to close and sometimes spawn new ads when you attempt to get rid of them.

This isn’t just annoying but also consumes bandwidth and system resources, leading to a slowdown in performance. Additionally, some adware is capable of tracking your online activities and collecting data. This is a breach of privacy, so you definitely want a top-notch antivirus to protect you.

In worst-case scenarios, adware serves as a gateway for more malicious software, like viruses, spyware, and ransomware. These types of malware can have severe consequences including data loss or theft. Like with most cybercrimes, the end goal is stealing as much money from the victim as possible.

Best Ways to Prevent Adware From Getting Onto Your System

Adware can be quite pesky and harmful to your system’s performance and security. It’s essential to take preventative measures to keep your computer free of adware. Here are some of the best practices:

• Install a reputable antivirus. Use reliable antivirus software with real-time protection, like Norton, Bitdefender, or TotalAV. This will detect any adware you already have and block future programs before they’re installed.
• Keep your software updated. Make sure you’re always using the latest version of your operating system, web browser, or other software. Adware (and all forms of malware) often exploit vulnerabilities in outdated software.
• Be cautious with downloads. Only download software and files from reputable and legitimate sources. Be wary of faulty torrents, freeware, and shareware sites as they often bundle adware with their downloads.
• Use an ad blocker. Pop-ups are a common method used to spread adware. Use an ad blocker to prevent them from appearing, though you’ll still want to use an antivirus to remove the cause of them from your device entirely.
• Avoid clicking on suspicious links. Be cautious about clicking on links or ads that promise something too good to be true. They might be disguised as something legitimate but they can install adware onto your system. Links embedded in strange emails should especially be avoided.
• Read installation prompts carefully. When installing new software, opt for the custom installation and deselect any additional software (including browser extensions) that you are not familiar with. Freeware commonly comes bundled with adware products, so take it slow whenever you install free software.
• Stay informed about your cybersecurity. Keep up with the latest adware threats and read about good online safety habits. Don’t use suspicious websites, avoid phishing scams or other social engineering scams, and remember that clicking a pop-up ad is like painting a target on your device and hoping nobody hits it.

By following these best practices, you can significantly reduce the risk of adware infecting your system, thereby ensuring a safer and more efficient computing experience.

Can Free Antivirus Software Protect Against Adware?

Free antivirus software can provide a basic level of protection against adware. As long as it comes from a reputable company, free antivirus software can provide you with easily accessible malware scans to clean your device of adware. However, free versions usually come with certain limitations in their functionality.

Also bear in mind that some free antiviruses are worse than bad — the worst are little more than adware-carriers themselves. Even legitimate free antiviruses lack advanced features like real-time protection, regular updates, strong firewalls, and other features that make premium antiviruses good. This means that while they can fend off some threats, they might not be equipped to deal with the latest or most sophisticated forms of adware.

Don’t get me wrong, there are decent free antiviruses. For example, TotalAV’s free scanner is pretty reliable. That said, I recommend getting a premium antivirus like Norton.

Frequently Asked Questions

Can adware slow down my computer?

Yes, adware can significantly slow down your computer. Adware often runs in the background and uses system resources like CPU and memory, which can cause your computer to become sluggish. It’s important to use an antivirus like Norton to keep your device squeaky clean.

Malicious adware can trigger an excessive number of pop-up ads too, which further strains your system. Even some legitimate adware is poorly coded and causes system instability, which is only made worse if the adware comes from a bad actor. Plus, it can be a gateway for further system-damaging malware.

Can I get adware on my mobile device?

Absolutely, mobile devices are not immune to adware. In fact, as the use of smartphones and tablets continues to rise, they are increasingly becoming targets for adware. Adware on mobile devices usually manifests as unwanted ads popping up or even as icons appearing on the home screen.

These ads can consume data, slow performance, and create a frustrating user experience. It’s crucial to install a reliable security app and be cautious about the apps and files you download on your mobile device.

Why is clicking on pop-up ads dangerous?

Clicking on pop-up ads is dangerous because it can lead to malware infections, including adware, spyware, and trojans. Cybercriminals often use pop-up ads to distribute malicious software. These ads may appear legitimate but can redirect you to unsafe websites or trigger automatic downloads of harmful software.

Some pop-up ads might be phishing attempts aiming to trick you into revealing sensitive information. It’s advisable to avoid clicking on pop-up ads entirely, especially if they appear intrusive or originate from an unknown source.

What are the different types of adware?

There are primarily two types of adware: legitimate and malicious. Legitimate adware is usually bundled with free software and displays advertisements as a way to generate revenue for the developer. While it can be annoying, this type is typically not harmful.

Malicious adware, on the other hand, is designed to display ads without the user’s consent, often in an intrusive manner. It can also collect personal information without permission and be used to promote malware-ridden applications. Fortunately, both kinds can both be stopped with Norton and other top antiviruses.

What other kinds of viruses can I get from adware?

Adware can serve as a gateway for various other viruses and malware. Once the adware is installed on your system, it might download additional malicious software such as trojans, spyware, and ransomware, and the advertised apps, games, etc, may be home to additional digital nasties.

Trojans can give hackers remote control over your system, spyware can collect your personal data, and ransomware can encrypt your files, holding them hostage until a ransom is paid. This makes it vital to remove adware promptly and employ robust security measures to keep your system protected from a range of threats.
