Oh, Really?
So you can compress using UPX again, then upload to virustotal.
Check it out, ;)
Thanks

I have enough experience with UPX to know that it's a fairly good packer.
If you placed the backdoor into the code yourself, I'm not surprised
that the packed version is UD by most virus-scanner.
Doesn't make it any less of a backdoor.
