Microsoft Virus

I keep receiving a pop-up on my PC screen (Windows 10):

Microsoftalerts83[dot]com says:

YOUR COMPUTER HAS BEEN BLOCKED

Error # 3658667d3676a01

It also says to call (877) 765-8529

How do I get rid of this? I'm assuming it's a virus on my computer even though I have virus protection.

You usually arrive at one of these Tech Support Scam sites by way of a redirect when you click on a link to something else, and most of these fake security/virus warning sites don’t download any kind of file-based malware, so they generally aren’t being detected by AV/Antimalware apps. The scam site just immediately runs a script that loads the fake alert dialog, and since the dialog that it uses is application modal, the script is able to lock up your browser by just reloading (looping) the fake alert dialog every time you try to close it by clicking on its OK Button:

In any of the several browsers that implement Dialog Loop Protection (including Microsoft Edge), you actually have to click on that OK button in the fake alert dialog in order for the browser to detect the dialog loop and respond by adding the Dialog Loop Protection checkbox – which then allows you to escape from the lockup and close the page:

Unfortunately, this kind of Dialog Loop Protection is very confusing – first of all because we've all been warned repeatedly not to click on anything that looks suspicious; and secondly because the content of the fake alert dialog is actually under the control of both the malicious website and the browser’s Dialog Loop Protection mechanism, and the user is therefore put in the difficult position of having to decide what part of the dialog is legitimate and what part isn’t.

The latest variants of the Tech Support Scam take full advantage of this built-in confusion by spoofing both the address bar URL and the Dialog Loop Protection checkbox in the fake alert dialog:

There’s a great real-world example here:

The Tech Support Scam is undoubtedly the most prolific and long-lasting scam ever perpetrated via the internet, so it’s pretty discouraging to see these belated and confusing responses on the part of browser developers. You can help raise the level of awareness for this issue by reporting these scam sites directly to Microsoft and the local authorities:

Click the OK button at the bottom of the popup. You should then see a box Do not allow this site to create new pages. Check it and then close the window.


If that doesn't work, for Edge, follow the instructions by Scott_Ki here:

For all other browsers:


Use the Task Manager to exit the browser. Reboot and see if the pop-up goes away.
