Hi @Normen ross ,
It is better not call that number.
You might meet a phishing scam. The Windows Defender security warning is a particular scam that is commonly referred to as a phishing scam. And what that means is that it tries to emulate an actual warning or error message to get the users to download something or contact a bad actor to continue the ruse.
If you get this error message as a pop-up once or twice, maybe consider what websites you’re browsing when they appear. Otherwise, just close and ignore them. However, if this is happening every time you use your browser, this could be symptomatic of malware that has been installed.
Since this issue is not relates the Asp.net core Blazor, and it is currently not supported in the Q&A forums, the supported products are listed over here: https://learn.microsoft.com/en-us/answers/products (more to be added later on). I will remove the dotnet-aspnet-core-blazor
tag, and add the not-support
tag. Hope you can understand that.
Best regards,
Dillion
