Has My PC Been Hacked

A single SYN_SENT entry from netstat does not by itself prove remote access. It means a connection attempt was in progress. If the entry appears only sometimes, that can be normal background activity from Windows or an app.

A better way to check is:

1. Review recent Microsoft account sign-ins.
   Go to the Recent activity page and check sign-ins from the last 30 days. Look for devices, locations, or app activity that are not recognized.
2. Change security settings if anything looks suspicious.
   Update the password again if needed, review security settings, and remove trusted devices if necessary.
3. Run a full malware scan before changing passwords again.
   In Windows Security, open Virus and threat protection > Scan options > Full scan > Scan now. This is important because malware on the PC could capture a new password.
4. Keep the browser and Windows updated.
   Compromised or malicious webpages can use software vulnerabilities to infect a PC, so keeping the browser and Windows current reduces risk.
5. Use TCPView for a clearer live view of connections.
   TCPView shows active TCP and UDP endpoints, the local and remote addresses, connection state, and the process that owns each endpoint. It is easier to interpret than netstat for checking what is currently connected.
6. If the Microsoft account may have been compromised, also review account settings.
   Check connected accounts, forwarding, and automatic replies, because those settings can be changed after unauthorized access.

Since the password was already changed and a security scan was already run, the next best checks are the Recent activity page and a live connection review with TCPView.
