I hope i helped fight malware (my first ever post)

You sure did, thanks.

But for future reference, please don't upload the files here as other forum users may download the malware and infect themselves.
Instead, please upload the files here: http://uploads.malwarebytes.org/

Yeah i realised that i would of removed but there wasn't any edit button but still glad i could help

Yeah, unfortunately you don't get the edit button until you reach at least 50 posts. The mods implemented this policy due to some users altering their logs in the HijackThis help forum area.

Hi Serious, welcome to the forum and nice first post.

I already had a InstallAVg_880116.exe in my samples at the same size but packed differently.

As you can see my older installer is getting flagged by quite a few engines where as your newer installer isn't.

Yeah, only 3 flagged it, and one of those that did (F-Secure) only caught it with heuristics (meaning it didn't have a specific definition for it, it just looked suspicious). Good find.

Very interesting. I can't wait till malwarebytes see's this as 'infected'
