See Who Your PC's Talking To

For as long as internet access has been common, so has the level of concern over programs which "phone home".  When you install software on your PC, does that program make silent connections over the internet, back to a server somewhere?  If so, why?  Is it purely for harmless purposes such as checking for updates?  Or could it be sending your confidential data elsewhere?

If you suspect that such activity has been taking place on your PC, or you merely want some assurance that it is not, take a look at the Moo0 Connection Watcher.  It's a free utility which tells you which programs are currently communicating over the internet from your PC, or listening for incoming connections.  It also tells you the name or IP address at each end of the connection, and the number of bytes sent and received since you started the program.

The Moo0 Connection Watcher is free, and you can get it from http://www.moo0.com/software/ConnectionWatcher

 The download is around 3 MB, and it should work on all recent versions of Windows including 8.  It's malware-free according to Web of Trust and VirusTotal.  It's also available as a portable version, and that's the one I used, although there's an installable version too if you prefer.  Personally I recommend using portable software when available, as there's nothing to install and thus removing the product if you no longer use it is simply a case of deleting the files from your computer.

Another advantage of portable versions is bypassing Registry bloat!

Looks like it is just a GUI for Netstat.

And you could go one step further and install a portable applications administrator program e.g. PortableApps (other software is available) on your hard drive to run and maintain all your portable software in a user friendly interface.

Thanks. Portable worked as advertised on Win7 32bit.
TeamViewer was listening in...hmmmm.

Found this at the bottom of the download page:

Received / Sent fields are always 0.

Due to Microsoft's decision, the information is no longer available on Vista (Service Pack 1) and later. It may still be accessible if you specifically "Login as an Administrator", but not by just "Run the program as an Administrator". There is no problem to use it as an normal user before Vista (Service Pack 1).

Thanks Rob for the useful Moo0 Connection watcher.
I am going to download portable version.
Years ago I decided to go in that direction because (I use your own words): "using portable software when available, as there's nothing to install and thus removing the product if you no longer use it is simply a case of deleting the files from your computer"
