Internet Security Alert pop-ups

Hello, I keep getting a audible pop-up screen in full red page saying 'Internet Security Alert' and not to shut down my computer. The web address is and gives a phone number to call. I took a screen shot and will post if I can. The only way to get rid of this screen is to 'control, alt, delete' to bring up the task master and 'end task' from there. It pops-up every time I open a browser in Firefox. What is this? Is it a true security alert? I have received this alert since I bought the new laptop in November, 2017. How do I get rid of it if fake? Thank you.

If only in a browser

It's something that has become attached to the browser.

These are usually and so far always fakes to get you to go to some site to download a fix or call in and pay up.

If you have saved your bookmarks and cookies (Mozilla and the web have told how many times) just reset the Firefox browser and reload your bookmarks and cookies if you think you need them.

Hey, Rae
The audio message is fake, do not pay attention, but do not ignore the problem.

Here is what I suggest doing.
1. Go to about:addon (paste into the address bar) and Remove unfamiliar, recently downloaded extensions.
2. Tap Ctrl+Shift+Delete keys and clear all browsing data (choose the right time range first!)
3. Install a legit malware scanner to check if malware exists (remove if it does!).

If you complete these steps, the audio message should be gone.
Good luck!

You have to be careful, a lot of scams nowadays!

it is a scam

I have no doubt it is a scam because it provides a telephone number. Genuine alerts from the system and legit tools never act this way, instead they describe the problem and suggest what can be done about it. Thus, if you are seeing a warning that makes you panic and asks to call someone, always know it is a scam. Fake alerts might get in together with adware, so to get rid of it I would recommend removing all suspicious programs and extensions that you have recently downloaded. Plus, it might be a good idea to reset your Mozilla Firefox. If the fake alert still comes back you should install a legitimate anti-malware tool and do a full system scan with it.

You been scammed...

It is most likely a scam. You may have clicked on an unsafe third-party banner or pop-up ad or link before while visiting some suspicious website (torrent, video streaming, dating, betting, gaming, etc). But, if this pop-up keeps appearing, chances are you have infected your computer with a browser hijacker or an adware program.

I suggest that you check your Extension/Add-ons Manager and remove all suspicious tools. Open your Control Panel and your installed programs list, and uninstall any recently installed suspicious applications.

Finally, I would also advise you to install the free version of Malwarebytes and/or AdwCleaner, which can detect and eliminate most malicious and potential threats.
