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 (,, 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 2.25:

  • Added 'Hide Items With Loopback Address' option (Hide items that their Local Address or Remote Address is or ::1 )

A useful tool that deserves a place in your security toolkit

WhatsApp Messenger 2.16.11

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's new in 2.16.11?

 - Due to a bug in iOS 10, your notification sounds may not properly play until you restart your iPhone (press and hold the power and home buttons for 10 seconds).
- In groups, you can now mention specific people to get their attention by typing the @ symbol and choosing someone from the picker. 
- When forwarding messages, you can now send to multiple chats at once 
- Ask Siri to send WhatsApp messages or place WhatsApp calls (iOS 10+) 
- Answer WhatsApp calls right from your lock screen, just like a standard phone call (iOS 10+) 
- A new Widget lets you quickly jump to a recent chat or see which chats have unread messages (iOS 10+)
