PeStudio
Analyse any Windows executable for signs of malware

PeStudio is a free and portable tool which uses static analysis (and other techniques) to help you discover more about suspicious applications. The program is aimed squarely at developers and Windows experts, but don't let that put you off - there are features here which everyone can use and understand.

Getting started, for instance, is as easy as dragging and dropping a program onto PeStudio. A detailed report appears almost immediately, and the first Indicators tab delivers plenty of useful information. Is it digitally signed, for instance? Targeted at 32 or 64-bit processors? Does it need administrative permission? And there are details about ASLR, DEP, SafeSEH, resources and more.

Clicking the Strings tab will then reveal any embedded text strings in the program - function names, paths, prompts, web addresses and more - which can be a useful way to figure out what it's doing. (Malware will usually employ various tricks to hide this kind of information, but it's still worth a try.)

The Libraries and Imports tabs show you the DLLs and other support files required by your program, and the functions it's using.

The Resources tab will list structures embedded within your program (typically icons, bitmaps, dialogs and so on).

Usefully, clicking Indicators > VirusTotal Scan Report will tell you whether any of the VirusTotal antivirus engines (46, as we write) thinks the executable is malware.

And PeStudio even comes with command line support, which means you can automate its analysis and check a host of files in a single operation.

Verdict:

A nicely balanced malware analysis tool, PeStudio has some useful features for regular users, while also providing the more in-depth details experts need

Unreal Engine 4.7.2.0

Free Full Commercial Software

Unreal Engine is Epic Games' game engine, a powerful suite of tools for developing anything from basic 2D games to professional RPGs, first person shooters and whatever else you like.

Wide standards support - DirectX, OpenGL, JavaScript/ WebGL - means your projects can be targeted to almost any platform: consoles, iOS, Android, Windows, OS X, Linux, HTML5 browsers and more.

There's a vast amount to learn, of course, and that's even before you start building your game. But there's plenty of documentation, tutorials, demos and sample projects to point you in the right direction.

The package is now entirely free, too - no annoying limitations, nag screens or anything else. Epic now only requires that you pay a 5% royalty after the first $3,000 of revenue per product per quarter. And even then, you "pay no royalty for film projects, contracting and consulting projects such as architecture, simulation and visualization."
