Posing as warnings from antivirus software companies, scareware notifications use social engineering fear tactics to convince people that supposedly critical malware infections need to be urgently resolved.
After tricking victims into paying for the scam software, scareware often then infects them with the very same type of malware it had promised to remove. And so long as the scammers’ malware is on your system, you remain vulnerable to additional extortion attempts like ransomware attacks, or the use of spyware to steal your credit card information and commit identity theft.
The first indication of scareware is a barrage of notifications or banners appearing on your screen. These fake antivirus pop-ups are designed to cause panic by warning you about urgent security breaches — probably with all-caps text and lots of exclamation points. With the spread of iOS and Android scareware, it’s important to stay alert across platforms and operating systems.
The first sign of scareware is a barrage of notifications appearing on your screen. These pop-ups are designed to cause panic by warning you about urgent security breaches.
Legitimate cybersecurity companies will never use such invasive fear-mongering tactics to promote their products. In fact, the more dramatic and persistent these alerts are, the more likely they are to be scareware. Even if you’re sure a notification or product offering is genuine, always verify new software with a quick web search before downloading it.
Unlike real virus removal tools, malware also typically reduces your computer’s performance. And you’ll likely see even more pop-ups after installing scareware. So even if you identify scareware only after the fact, you should act immediately. Every minute you wait exposes you to further vulnerabilities and increases the risk of identity theft.
The most common scareware examples are all some variation of the classic virus removal scam. Fake virus pop-ups or notifications usually claim that the user has multiple infections that will have dire consequences if they’re not immediately removed.

Sometimes these computer virus pop-ups will even misrepresent themselves as coming from your operating system, or another trusted source. The Google virus alert scam is one such tactic used to scare people into downloading malware.

Another deceptive malware technique favored by scareware scammers is to use phony “Close” or “X” buttons, which will automatically install malware when clicked. Lots of online ads use the same trick.
If you accidentally download scareware, you may get a program that at first glance appears to look and act like real antivirus software. But in reality, the sham software is always a total dud, offering zero protection against real cyber-threats.
If you’ve unwittingly downloaded scareware onto your device, you need to remove it immediately. Deleting the download is a good place to start with scareware removal, but you may miss more stubborn programs or files left behind by the malware. For this, you’ll need to install genuine antivirus software that can root out any lingering traces.
Here’s how to remove scareware in three steps:
Since the scareware will be hiding in plain sight as an apparently legitimate antivirus program, identifying and uninstalling the offending download should be fairly straightforward.
Type control panel into your Windows search box, then select Control Panel from the results.
Under the Programs category, select Uninstall a program.
Once you’ve located the scareware, click Uninstall and then OK if a confirmation box appears.
Locate the unwanted program in the Applications category of your Finder window. Click and drag it to the Trash, or right-click and select Move to Trash.
Now empty the Trash to remove the software once and for all.
Next, restart your computer in Safe Mode with Networking so that you can install malware tools without exposing your computer to further threats.
Restart the computer via the Power button in the Start menu, making sure you hold the Shift button as you click Restart.
Once your computer restarts, select Troubleshoot on the advanced reboot options menu.
Choose Advanced Options.
Go to Startup Settings.
Press F5 to select Safe Mode with Networking to boot into Safe Mode with internet access.
Shut down your device as normal and wait 10 seconds. When you restart your Mac, immediately press and hold the Shift key until the log-in screen appears. You’ll now be in Safe Mode and can log in normally.
Once in Safe Mode, you can safely download legitimate malware removal tools to find and remove residual scareware files. On a mobile device, use dedicated malware removal software for Android, or an iPhone virus scanner.
Install Avast One and run a full virus scan to clean out any other malware on your device. You can also schedule a boot-time scan to run when you restart your computer. This is a very deep scan that roots out the most hidden forms of malware lurking deep in your machine.
After installing Avast One, you’ll benefit from real-time and round-the-clock smart analytics that can identify and remove even the latest viruses and other malware. You’ll also get multiple layers of enhanced security to block malware before it ever reaches your machine.
Scareware uses social engineering tactics to manipulate users into compromising their own security. Staying informed and following these simple tips can help you spot scareware attacks before you fall for the ruse.
Never click on malware notifications. If you see a pop-up, banner, or window warning you that your computer is infected and prompting you to download a software solution, it’s almost certainly a scam. Do not click.
Keep your browser updated. This helps protect against scareware pop-ups in the first place. Enabling automatic updates ensures you’re always using the latest version of your browser. Better yet, use a secure and private browser for an extra shield against scareware and other online threats. Avast Secure Browser even blocks phishing attacks, harmful downloads, and helps prevent web tracking — all for free.
Use the full range of network tools. Using ad blockers, URL filters, and firewalls helps to cut scareware off at source and stop fake malware warning pop-ups from ever reaching your screen.
Avoid accidental downloads. To get rid of scareware pop-ups, close the browser window itself, instead of clicking the “Close” or “X” buttons. On Windows, use Ctrl + Alt + Delete to open the Task Manager. There, find the program under the Applications tab and click End Task.
Always use genuine antivirus software. Using updated protection from a trusted security company is the best possible defense against scareware, because it will alert you to potential threats and swiftly quarantine and remove any malware that does make it onto your computer.
Knowing what scareware is and how to avoid it helps guard against fraudsters who rely on manipulating unsuspecting victims with their scams. But nothing offers the same level of reliable protection as a comprehensive and cutting-edge antivirus app that defends against all the very latest threats.
Avast One packs a powerful array of advanced protections to prevent any malicious software from slipping onto your machine. Using state-of-the-art machine-learning technology, Avast proactively seeks out and blocks viruses, spyware, and ransomware before they can threaten your privacy and security.
