CurrPorts (64-bit)
Monitor open internet and network connections

If you've been infected by spyware or a virus then this will often try to make an internet connection, "phoning home" for more instructions on what to do next. And to make this happen it will need to open a TCP/IP or UDP port on your PC. If you're worried you've been infected by malware, then, run CurrPorts may tell you more. It'll list every currently open port, and (usually) the process that opened it, giving you a good chance of detecting any suspicious activity.

Don't panic just because CurrPorts has a lengthy list of programs, though. That's quite normal, and most of these will be innocent. On our test PC, for instance, processes with open ports included AppleMobileDeviceService (an iTunes component), our antivirus tool, Internet Explorer, Outlook, Skype, and lots of Windows components (lsass.exe, services.exe, svchost.exe, wininit.exe and more).

To get a better feel for potentially risky connections, check the CurrPorts Remote Address and Remote Host Name columns. If these are blank, or list addresses that correspond to your PC or network (0.0.0.0, 127.0.0.1, a network address or your PCs network name) then the connection is unlikely to be a problem. If the remote address corresponds to an internet IP address, though, and you don't recognise the process responsible for the connection, then that may require more investigation.

The program can also close particular connections on request (right-click and select the Close option). And if you click View > HTML Report then CurrPorts will produce a detailed report on everything it's discovered. Save this now, and you'll have a baseline that shows the ports your PC has open normally. Then, if you run CurrPorts in a month, say, any new open reports will be immediately obvious.

Version 2.51:

- Added 'Creation Timestamp' column, which displays the date/time that the connection was created. Be aware that this information is not available for all connections and it works better on Windows 10.

Verdict:

A useful tool that deserves a place in your security toolkit

Windows 10 October 2018 Update (build 1809)

Free Full Commercial Software

This is the latest version of Windows October 2018 Update. it's a media creation tool that can be used to upgrade an existing installation of Windows or create installation media for another PC. Just make your choice after launching the tool and it'll do the rest.

What was new in Windows 10, when it was released? The OS brought back the Start Menu, though with a Windows 8 twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

Apps now work much more like regular desktop programs. They have minimise, maximise, restore and close buttons, and can be resized (to a degree) and organised however you like.

If you've still lost track of a program in the mass of open windows, a new Task Spaces feature can help. Click its taskbar button and you'll see thumbnails for everything running now, a little like OS X's Mission Control - just click something to switch to it.

Better still, Task Spaces also supports virtual desktops. Add extra desktops as required and it'll display thumbnails of each one, making it easy to identify whatever you're after and switch to it.

There's also smarter snapping, new customisation options, and even a bunch of experimental additions to the command prompt.

Fall Creators Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO here will give you build 1809 which is the October 2018 Update.
