Validating registry security key quicktime
This list (a very small part of our SG Ports database) includes TCP/UDP ports currently tested by our Security Scanner, and corresponding potential security threats.

To stop the popups you'd need to filter port 135 at the firewall level or stop the messenger service.

The Windows Incident Response Blog is dedicated to the myriad information surrounding and inherent to the topics of IR and digital analysis of Windows systems.
This blog provides information in support of my books; "Windows Forensic Analysis" (1st thru 4th editions), "Windows Registry Forensics", as well as the book I co-authored with Cory Altheide, "Digital Forensics with Open Source Tools".
The best protection is to turn off File and Print Sharing, or block ports 135-139 completely. Keep in mind that you might still be leaking out information about your system that can be used against you (such as your computer and workgroup names) to the entire Internet, unless ports are filtered by a firewall.

Sygate Personal Firewall comes with a default rule set that blocks all udp requests, however if udp requests originates from source port 137 or 138 they are allowed, thus a malicious person could get access to all open udp ports on a target merely by sending all requests from source port 137 or 138.
