If you’re unfortunate enough for your Mac to be infected with malware, you’re likely experiencing a flood of phony virus notifications. The only thing worse than not dealing with the situation is clicking on one of these pop-ups — accidental or otherwise. This will only make a bad situation worse, so learning how to stop virus notifications is essential.
Read on to find out how to recognize a fake virus notification, where these threats come from, and what you can do to get rid of a Mac virus alert pop-up.
How to recognize a fake virus notification on a Mac
Let’s start with some signs of a fake virus notification so you know what to look for.
They’re badly designed and may use poor grammar
There are 2 elements that cyber attackers tend to cut corners on: graphic design and grammar. Malware-infected ads and fake notifications are usually amateurish in appearance, and the English grammar can be laughably bad.
Right away, this should flag the ad as a potential threat. No legitimate company would produce ads like this.
Fake virus notifications try to scare the living daylights out of you
Most legitimate ads try to sell to you based on the advantages of buying their products. A fake ad, on the other hand, tries to freak you out.
A malicious pop-up will send out flares, red flags, and alarm bells, (ironically) informing you about viruses on your Mac, urging you to click the ad immediately.
Virus notifications appear suddenly without your consent
Naturally, malware is something that appears on your computer without your permission. So, if you suddenly get suspicious-looking ads or browser notifications on your screen, you could have an intruder lurking.
They’re asking for personal information
No authentic ad is going to ask for personal details. If the ad asks for a credit card number, date of birth, social security number, or the name of your first pet, don’t proceed.
Virus pop-ups have strange, garbled URLs
If an ad was to come from Moonlock, the destination URL would be something like https://www.moonlock.com/spyware (for example). This is clear and professional, and it clearly telegraphs the link’s destination.
If, however, a destination URL is a jumble of letters and numbers with an unclear domain, think twice.
Note that you can see a destination URL before you click by putting your cursor arrow over the ad. The URL will appear at the bottom-left of the browser.
How to get rid of virus notifications on a Mac
If the symptoms in the previous section match what you’re experiencing, you may have malware on your Mac. So, how can you stop getting virus notifications on Mac? And is there a way to remove malware from your device?
Run an antivirus scan
We’ll go more in-depth on this topic later in this article, but this should be your first course of action. In many cases, running an antivirus scan will remove the malware and fix the issues.
Check browser settings or reinstall the browser
Suspicious ads can also come from a browser hijacker. Check your browser settings for any changes you didn’t approve of. Or, to be extra safe, you can uninstall and reinstall the browser altogether.

Update your Mac
Finally, you should always check to see if there are any Mac updates waiting to be installed.
Malware always takes advantage of system vulnerabilities, so you should start by updating to the latest version of macOS. This is especially true if you’re running any public beta versions of macOS. They are never perfect until the final version comes out.
How to remove virus notifications on a Mac using CleanMyMac
The fastest way to stop fake virus notifications on Mac is to use CleanMyMac powered by Moonlock Engine. This is a lightweight and effective antivirus program that will find malware on your Mac and immediately remove it for you.
- Open CleanMyMac and select the Protection tab on the left. If this is your first time using the software, you should click Configure Scan first and choose every option, including Deep Scan.
- Close the settings and click Scan. CleanMyMac will leap into action and thoroughly go through your Mac, looking for malware threats, such as the source of the fake virus notifications.
- When the scan has been completed, CleanMyMac will show a list of results. Tick all the boxes and click Remove at the bottom right.
To have a 24/7 malware monitor that never sleeps, go back into the settings and select Enable Malware Monitor and the option to look for threats in the background. Once you’ve done that, you’ll get instant malware alerts next time.
Hopefully, there won’t be a next time, but you never know.
What is a fake virus notification, and how does it work?
A fake virus notification occurs when a malicious pop-up on your Mac screen tells you that your machine is infected. You’re then urged (through scary and aggressive language) to click a link to buy their “antivirus software.”
Clicking this link, however, can release more malware or lead to a download page that will only cause more trouble for your Mac. The attackers are likely seeking to steal your personal details, which you will be asked to enter on their website to buy the product.
Why do fake virus pop-ups appear on your Mac?
This type of malware can come from several different sources. It almost always comes from other malware that’s made its way onto your machine. Perhaps you clicked a malware-infected link, installed software with trojan malware hiding inside, or have a remote access trojan (RAT) on your system.
Always be careful to distinguish between fake virus notifications and genuine Apple alerts. Apple will alert you to new system updates and any genuine apps that want notification access.
What can a virus alert pop-up do to your Mac?
Virus alert pop-ups can have multiple negative effects on your Mac. Here are some of them:
- Introduction of more malware: Malware spawns like mice. One leads to another, which leads to another.
- System instability: Left unchecked, virus alert malware will make your Mac unstable by slowing it down, overheating the CPU, and causing crashes.
- Data theft: The main purpose of malware is to steal your data. Therefore, a virus alert pop-up can and will lead to personal data on your Mac being stolen.
- Financial losses: If you buy a piece of malicious software being pushed on you, or if more malware finds it on your device, your credit card number will be stolen and used. Consequently, financial losses and big credit card bills may await you.
What to do if you keep receiving virus notifications on your Mac
In most cases, running CleanMyMac should deal with the problem instantly. But malware can be a pest. It can mutate and slip past antivirus platforms.
If you continue to receive virus notifications on your Mac, what should you do? Try the following.
Run another malware scan with CleanMyMac
A second malware scan with CleanMyMac will help clear away all the debris from a malware infection. There may be a few related files that CleanMyMac missed the first time around. Run it again to see if it can find anything else.
Look for apps that you didn’t install
Malware often runs in the form of an app installed on your computer. Go to your Applications folder and look to see if anything unrecognized is there. If so, delete it immediately. You can do this properly using CleanMyMac.
Look for suspicious running processes
If malware is running, it will show up in the Activity Monitor. Open Activity Monitor, sort the list by the processes that are consuming the most CPU and memory, and see what shows up. You have the option to force-quit the processes.
Be careful when force-quitting — some processes are essential for the running of your Mac. Run a web search to see what a process is before you force-quit it.
Wipe and reset your Macbook to factory settings
If you’ve gotten this far and still have fake virus notifications, it may be time to consider wiping and resetting your Mac or MacBook.
We’ve provided an in-depth tutorial here. You can also watch the following video to get even more information.
Always make sure you’ve backed up all your data before you wipe and reset your machine.
The process of stopping fake virus notifications on Mac can be annoying, but it’s essential. Malicious pop-ups are not only dangerous to your system but can compromise your private data. They should never be ignored. As time goes on, the problem will only get worse, and the damage to your data will multiply.
