I have created a new project with the template Blazor WebAssembly 3.2.0, and I have published locally IIS on windows 10, and the antivirus software is blocking the dlls files, i changed the file extensions but the antivirus blocks the files too, the antivirus software is sophos web protection.

I used the following lines to changes the dlls extension files, but it did not work.
dir ._framework_bin | rename-item -NewName { $_.name -replace ".dll\b",".blazor }
((Get-Content ._framework\blazor.boot.json -Raw) -replace '.dll"','.blazor"') | Set-Content ._framework\blazor.boot.json
