It happens when you try to sign something, It will dump an infected signnp.exe in %appdata% Local/bin/signnp.exe.
I found this out when Bullguard antivirus gave me the heads up.
This man who wrote this program you should immediately stop donating to if you already are,
until this issue is resolved.
Cannot Take a screen shot now whereas my computer is running a fullscan offline, but to prove it download the bullguard trail and you will know that I am correct when using it.
This tool was written to help people who are struggling to get the signing tools provided by hackinformer.com working; But obliviously Leecher/Lman wanted a bit more than that.
Just trying to warn those with poor/no antivirus on their pc's.
*EDIT*
Can You Really defend him from this, Downloaded the program from his google sites.
