VirusBarrier X6: I keep receiving alerts that Skype is attempting to use a port. How do I stop this?

VirusBarrier X6 lets you control access from your Mac to the Internet and local networks by individual applications. While your firewall settings may allow general network access, the Anti-Spyware tab lets you choose how VirusBarrier X6 reacts when specific applications try to access the network. This helps you in two ways:

  • You can prevent users from accessing the network with specific applications.
  • If an application attempts to connect to the network behind your back, VirusBarrier X6 stops it in its tracks, alerts you, and waits for you to decide whether to allow it to do so or to block it.

Your Mac has many applications that access the Internet or other networks, including web browsers, e-mail programs, FTP (file transfer) programs and instant messaging applications. But there may also be programs that connect to the network without telling you, in order to verify the serial numbers of software installed on your computer, collect and send personal information without your awareness, or open a backdoor on your Mac to provide access to hackers or vandals. VirusBarrier X6 notifies you of such attempts and allows you to decide whether to allow them.

If you do not want Skype to have full Internet access, please contact Skype for a list of ports that the application needs to function properly.  You can allow access to only these ports for better security.

If you understand the implications of giving Skype full Internet access and still would like to do so, please follow the instructions below.

Launch VirusBarrier X6, click the Privacy button at the top of the window, and click the Anti-spyware tab below.  Highlight Skype in the list found in the left-hand column in this window.  To the right, in the list, find Undefined port behavior and set it to Allow outgoing connections.
