Sander Wiebing a241792e10 Reduce FP of legitime processes
A lot of Windows apps does not have any file characteristics. Some examples:
- Gamebar: C:\\Program Files\\WindowsApps\\Microsoft.XboxGamingOverlay_3.38.25003.0_x64__8wekyb3d8bbwe\\GameBarFT.exe
- YourPhone: C:\\Program Files\\WindowsApps\\Microsoft.YourPhone_1.20022.82.0_x64__8wekyb3d8bbwe\\YourPhoneServer/YourPhoneServer.exe

All C:\Windows\System32\OpenSSH (scp, sftp, ssh etc) does not have a description and company.

Python 2.7, 3.3 and 3.7 does not have any file characteristics.

So I don't think it is possible to whitelist all options, maybe it is worthwhile to check the \Downloads\ folder otherwise it would be better to just delete the rule. All other suspicious folders are covered by /rules/windows/process_creation/win_susp_exec_folder.yml

Sander Wiebing 2678cd1d3e Create win_netsh_fw_add_susp_image.yml

Combined the following rules for the suspicious locations:
