It's free! But lost in obscurity... http://updates.ikarus.at/updates/update.html Download both files. Run ikarust3scan.exe from your download location and specify a directory if you don't like the default. You will have two files, T3Scan.exe and t3.dll. Put the t3sigs.vdb in there, too, unless you want to path it on the command line. Run in Command Prompt. C:\PORTABLES\T3scan>t3scan -?

Got feedback from their support: "-n No Simulation" is a way to deactivate the file simulation the engine can do, this can be used to get a faster scan without heuristics and simulations.
