RDP Defender v2.4.6.1
When opening a remote desktop in public, you will get attack by an outbound robot/zombie computer, once they succeed in login your Windows, your computer will infect viruses and ransomware virus.
After install open the RDP Defender, you can see any blocked IPs
Tools > Options and Whitelist, you can setup whitelist here to bypass RDP Defender block and block detection.
For security I suggest don’t use the common port to access a remote desktop, you can set up NAT on the firewall/router let say translate unbound 2289 to inbound 3389 to reduce robot scanning, else you will found a lot of blocking on RDP-Defender.
