There should be no distribution of samples via this forum, it is a support forum and not a quasi malware distribution service.

Oops! many apologizes david..I have removed that from my reply I was only saying that because if anyone else wants to circulate the samples to some other AV vendors but I will take a note of that.

IDS flagged it here: http://urlquery.net/report.php?id=3533128
loaded will be kernel32.dll (where IsDebuggerPresent is located)
The circumvention is for a particular code example !
mov eax,dword ptr fs:[18]
mov eax,dword ptr ds:[EAX+30]
mov byte ptr ds:[eax+2],0

This will patch the IsPresent flag, ensuring IsDebuggerPresent always returns 0

Adware - two detect in latest scan: https://www.virustotal.com/en/file/411240f7d25a1a63a68b0874eb8d122c3b2c2e0bddb94eee55818b6a535b6915/analysis/ (installer detection -> Global\Phoenix_Installer (failed) & RasPbFile (failed), this issue is a class of bug called a "Token Leak"....

Adware. It was "Supposed" to be a movie. I noticed the .exe part at the end. I figured it'd be malicous, thought I'd see what I could do to help. This seems like a good place.
