Safely Close the Scam Warning and Secure Your Computer

The number 833-714-6359 is a confirmed tech-support scam. Follow these steps to safely force-close the fake alert and ensure your system is entirely clean.

Tech-support scams often use browser features to lock your screen in full-screen mode, making it seem like your entire computer is frozen. These are usually just malicious web pages and not actual viruses, but interacting with them can lead to data theft or malware installation.

Force Close the Browser

Do not click the 'X' inside the pop-up. Instead, press Ctrl + Shift + Esc on your keyboard to open the Task Manager. Locate your web browser in the 'Processes' list, right-click it, and select 'End task'.

Disconnect from the Internet

Temporarily disconnect your computer from Wi-Fi or unplug your Ethernet cable to prevent any background data transfer or remote access if malicious software was inadvertently downloaded.

Run a Security Scan

Open Microsoft Defender or your preferred reputable antivirus software and run a 'Full Scan' to detect and remove any hidden malicious files on your system.

Remove Unauthorized Software

Go to Windows Settings > Apps > Installed apps. Sort the list by 'Date installed' and uninstall any unfamiliar or suspicious programs that were added recently.

Change Your Passwords

Using a completely separate and trusted device (like your smartphone), change the passwords for your Microsoft account, email, and banking accounts as a precaution.

Official Microsoft Support Fact: Genuine Microsoft error messages never include a phone number to call. Microsoft does not send unsolicited emails or make unsolicited phone calls to request personal or financial information. Always contact official support only through support.microsoft.com.

Frequently Asked Questions

How do I know if a Microsoft support warning is real?

Genuine Microsoft error messages will never display a phone number for you to call. Official Microsoft support is only provided if you initiate the request directly through their verified website at support.microsoft.com.

What should I do if I already called 833-714-6359?

If you are still on the phone, hang up immediately. If you granted them remote access, disconnect your computer from the internet right away. Uninstall any remote access tools they had you download, run a full system virus scan, and change all important passwords from a different device.

Can these fake pop-ups infect my computer just by appearing?

Usually, the pop-ups themselves are merely deceptive web pages using JavaScript to prevent you from closing them. Simply seeing the message typically won't infect your PC, but clicking links within the window or downloading their recommended files will.

Why did this warning pop up in the first place?

These warnings generally appear when you are redirected by a malicious advertisement, when you visit a compromised website, or if your browser has a hidden adware extension installed. Keeping an ad-blocker enabled and practicing safe browsing habits can help prevent them.
