Sigcheck
Scan your PC for signed (and unsigned) files

Sigcheck is a command line tool which can provide details (link date, publisher etc) on an executable's digital signature. Sounds dull, yes - but wait. The program can also highlight unsigned executables, and even upload them to VirusTotal for detailed analysis.

For the most basic, details-only use, enter a command like sigcheck c:\windows\system32

Every executable file the program finds will have its digital signature checked and verified, then the signing date, publisher, description, product and more will all be listed.

Life gets more interesting when you start using VirusTotal, although Sigcheck does require that you accept the site's terms and conditions first. (Don't worry, there's nothing bad, but just follow the link to confirm that for yourself.)

With that done, enter a command like sigcheck -e -u -vn -vt c:\windows\system32

Now the program will scan your \Windows\System32 folder for unsigned files, then upload whatever it finds to VirusTotal, before listing anything that at least one of the engines thinks is malware. (It's not unusual for one or two engines to incorrectly raise an alert, so don't panic immediately, but you still need to investigate anything listed here.)

Sigcheck supports plenty of other command line switches. You can have the program show more version information, recurse subdirectories, query VirusTotal with file hashes, export its data in csv format, and more. Enter sigcheck at the command line for the full list.

Version 2.55:

Fix for a bug that caused the display of publisher names with commas to be truncated at the first comma.

Verdict:

An excellent security tool for anyone who might ever need to manually hunt down malware.

WhatsApp Messenger 2.17.31

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 Version 2.17.31

• Add color filters to your media. Just capture or select a photo, video, or GIF, and swipe up to pick a filter.
• When you receive multiple photos from the same sender in a row, they'll now be grouped together as an album.
• New reply shortcut: simply swipe right in any message to quickly reply to it.
