Remove “Virus Alert – WARNING” Fake Alerts (Microsoft Support Scam)

If your web browser is constantly being redirected to sites that display a Virus Alert – Warning notification, asking you to call a support number to fix it, then it is possible that you have adware program installed on your computer.

These “Virus Alert – Warning” alerts are nothing more a scam. Microsoft does not send unsolicited email messages or make unsolicited phone calls to request personal or financial information or fix your computer. Treat all unsolicited phone calls or pop-ups with skepticism. Do not provide any personal information.

Virus Alert pop-up

The bogus “Virus Alert – Warning” alert is shown in such a way as to trick the user into thinking their computer has crashed or that a virus has been detected on the computer. It does this to try and scare the infected user into calling one of the listed numbers in order to receive support. In reality, though, they will only be greeted with people who are trying to sell them unneeded support contracts and services.

The “Virus Alert – Warning” pop-up will have this message:

Action Required

Windows Virus Warning!

Identity Theft and Hacking Possibilities

Contact emergency virus support now – 1-844-345-5488
The system may find (149) viruses that pose a serious threat:


The scammer will typically attempt to get the victim to allow remote access to their computer. After remote access is gained, the scammer relies on confidence tricks typically involving utilities built into Windows and other software in order to gain the victim’s trust to pay for the supposed “support” services, when the scammer actually steals the victim’s credit card account information.

You should not purchase anything from numbers listed in these “Virus Alert – Warning” alerts. Whatever you do, please do not call the phone number for support because it is not Microsoft’s but rather a group of scammers waiting to rob you of hundreds of dollars under false pretenses.
The below instructions are for Windows users, however we also have an Android guide and a Mac OS guide which should help clean up your device.

How to Stay Safe Online

Here are 10 basic security tips to help you avoid malware and protect your device:

  1. Use a good antivirus and keep it up-to-date.

    Shield Guide

    It's essential to use a good quality antivirus and keep it up-to-date to stay ahead of the latest cyber threats. We are huge fans of Malwarebytes Premium and use it on all of our devices, including Windows and Mac computers as well as our mobile devices. Malwarebytes sits beside your traditional antivirus, filling in any gaps in its defenses, and providing extra protection against sneakier security threats.

  2. Keep software and operating systems up-to-date.


    Keep your operating system and apps up to date. Whenever an update is released for your device, download and install it right away. These updates often include security fixes, vulnerability patches, and other necessary maintenance.

  3. Be careful when installing programs and apps.

    install guide

    Pay close attention to installation screens and license agreements when installing software. Custom or advanced installation options will often disclose any third-party software that is also being installed. Take great care in every stage of the process and make sure you know what it is you're agreeing to before you click "Next."

  4. Install an ad blocker.

    Ad Blocker

    Use a browser-based content blocker, like AdGuard. Content blockers help stop malicious ads, Trojans, phishing, and other undesirable content that an antivirus product alone may not stop.

  5. Be careful what you download.

    Trojan Horse

    A top goal of cybercriminals is to trick you into downloading malware—programs or apps that carry malware or try to steal information. This malware can be disguised as an app: anything from a popular game to something that checks traffic or the weather.

  6. Be alert for people trying to trick you.

    warning sign

    Whether it's your email, phone, messenger, or other applications, always be alert and on guard for someone trying to trick you into clicking on links or replying to messages. Remember that it's easy to spoof phone numbers, so a familiar name or number doesn't make messages more trustworthy.

  7. Back up your data.

    backup sign

    Back up your data frequently and check that your backup data can be restored. You can do this manually on an external HDD/USB stick, or automatically using backup software. This is also the best way to counter ransomware. Never connect the backup drive to a computer if you suspect that the computer is infected with malware.

  8. Choose strong passwords.

    lock sign

    Use strong and unique passwords for each of your accounts. Avoid using personal information or easily guessable words in your passwords. Enable two-factor authentication (2FA) on your accounts whenever possible.

  9. Be careful where you click.

    cursor sign

    Be cautious when clicking on links or downloading attachments from unknown sources. These could potentially contain malware or phishing scams.

  10. Don't use pirated software.

    Shady Guide

    Avoid using Peer-to-Peer (P2P) file-sharing programs, keygens, cracks, and other pirated software that can often compromise your data, privacy, or both.

To avoid potential dangers on the internet, it's important to follow these 10 basic safety rules. By doing so, you can protect yourself from many of the unpleasant surprises that can arise when using the web.

9 thoughts on “Remove “Virus Alert – WARNING” Fake Alerts (Microsoft Support Scam)”

  1. I get these silly popups in Ubuntu, too. Linux, an OS that can run for months without rebooting… but usually it would say that my “Windows 16.04” system is infected… there is NO Windows version 16.04, it’s UBUNTU 16.04! So I know, for one, it’s fake because it supposedly takes the first sequence of numbers after the OS string it sees in the User-Agent string that EVERY browser sends and assumes it’s a Windows version number… Second, those clever fools think they can’t make me close my browser until I call a number… but no Ctrl-alt-del for me… (I could assign that to my LXDE desktop for LXTask… but I’m not now) instead, I hit ctrl-alt-f2, login, and then…

    killall –KILL firefox (or chromium-browser)

    Done. If not,

    sudo service sddm stop && sudo service sddm start

    But I’m just saying, these are ads. Nothing more or less. Even Linux users get hit with these here and there too.

  2. Thanks Stelian.
    I do have 1 more doubt. As I have been doing heavy reasearch,
    I found out about this self replicating message virus which sends out spam to all our contacts and also delete itself in the process,leaving us no way to know our phone has been infected by this spam virus.

    Is there anyway it can come to my phone without me actually clicking on actual the spam message?

    Does the android fake pop up virus contain this kind of malwares?

    Or are there any steps we can take to be precautious.

    Thanks in advance. I did go to the forum which you advised me to go to, I did ask a few Questions but honestly I was not answered much. Hence why im back here.

  3. Hello,
    Some ads can deliver malware. This type of malware is known as, malvertising and it involves injecting malicious or malware-laden advertisements into legitimate online advertising networks and webpages.
    There are plenty of cases of malicious scripts who can infected your machine, this is why is best to avoid shady looking websites.
    Now, on Android the type of “Virus Alert” scare-ware will mostly redirect you to Google Play to install an app called 360 Security from Qihoo… you do not need this app.
    But there are cases in which Android phones get locked by malicious ransomware apps.

    There are plenty of things to say about malware, and I would recommend that you join our forums (it’s free) – and ask all these questions, and our community will help you find the answers.

    Stay safe Coyle!

  4. Hi Stelian. Helping the society fight against cyber crooks is an awesome thing you’re doing. not tech savvy, could you specify what you mean by specific domain?
    Also can the fake advert itself do any harm to my android phone?
    As in, is there a chance a malware could have just crawled through in that time before I press the back button.
    Thanks again Stelian.

  5. Hello,
    If you only see this notification on a specific domain, then your machine should be fine. I do recommend that you install an Adblocker, and just to be on the safe side I would run a scan with Malwarebytes Anti-Malware Free.

  6. Hi all, I would require some help.

    I watch online streaming for soccer games and have encountered the fake virus ad many many times.
    I know it is a fake virus ad. So each time I see it I just press back and continue with my normal activities.
    Is this enough?
    Any help is much appreciated.

  7. Dude you r literally a life-saver. That stupid virus-removal ad was really becoming a pain but I did step #1 and the problem is gone. I had no idea it was that simple so from the bottom of my heart thank you!!!!!

  8. hi, i was introduced to ur site thru link re: windows10 ..btw i found it very informative thank you! …on ANOTHER NOTE, this virus your posted about and exceptional details i might add well ok i added lol, any way i just posted a 2nd msg regarding this messy virus that i have also come across while researching and found that some call it an injector injection code as simple as a piece of java script BUT WAIT as yal may think noooo BUT …I say YEAAH i’ve caught a glimpse of it today earler. using the OPERA browser, then in 2 separate computers 1 desktop 1 laptop … i’l put the link the full incident so i can sum it up a bit..

WRONG!!!

    i’m about to pull up the ‘GMER” scanner log and it show u

  9. Thank you very much! Whenever I use my laptop, I am constantly bombarded with the “Virus Alert” pop-ups, and could only get rid of them by using the end process feature of the task manager. But that feature also ended the sites I wanted to visit, and I had to start over again. This happened numerous times each time I logged on. I actually called the phone number provided by one of those alerts, and asked them how to get rid of their alert without closing the other windows. They either couldn’t or wouldn’t tell me. If they couldn’t tell me how to get rid of their own alert, why should I pay them to get rid of someone else’s virus. Your software really worked and, again, I sincerely thank you.
