Detects ClickFix-style activity where a user is tricked into entering or pasting malicious command strings into the Windows File Explorer address bar. This activity results in the spawning of common utilities like cmd.exe, powershell.exe, or certutil.exe with arguments associated with UNC paths, Base64 encoding, or download cradles (e.g., IEX, bitsadmin, or URLCache operations).
