Surely whitelisting these processes leaves you open to anyone just using these process names?

Surely whitelisting these processes leaves you open to anyone just using these process names?

I was thinking of it too and found this topic on windows official website: How to add a file type or process exclusion to Windows Security.
Which says that you can specify the full path, as well as use asterisk (*): C:\MyProcess\* will exclude files opened by all processes, located in C:\MyProcess, or any subfolders of C:\MyProcess.
This adds a bit of security

I have excluded Rider processes using the c:\myprocess\* format mentioned by @ryedigaryan above (but with the Rider root folder) and it seems to work well!

Thank you! You are a lifesaver for me! This is very convenient!

Before to run this script it's need to run from power shell:
Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass

Microsoft have a whole load of these processes on the following list https://learn.microsoft.com/en-us/defender-endpoint/common-exclusion-mistakes-microsoft-defender-antivirus#processes:

They say:

You shouldn't exclude some processes from scans, because attackers might use these processes. In general, don't define exclusions for the following processes.

They also recommend setting the fully qualified path to the file, not just the bare file name.
