How to check if a file is backdoored

Hey,

I'm curious as to know whether the file is backdoored or is FUD? What methods do you use to recognize it?

Thanks :)

Some words of Wisdom:
1. Never download or run any executable from here. 99.99% are FUD and or backdoored.
2. Never download or execute a file that doesn't have a virustotal scan attached.
3. Never download/allow transfer of files thru services such as Skype ® Teamviewer ® or any other related service.
4. If you must run the file, Do it in Sandbox AND OFFLINE! 100% of backdoored files cannot operate if your computer is physically not plugged into the internet. Just simply unplug the Ethernet cable from the computer.
You can also check if the file is binded with anything via Anubis: http://anubis.iseclab.org/

If you are struggling and need someone to talk to about something or want to vent about your IRL problems, I am just one PM away.
Simply check the file in a virtual machine
use the virtual machine as a host only
then it wont broadcast any information to anyone

do not scan executables on virustotal if you wish to keep it undetected by anti-viruses
don't download any unknown exe file.

"2. Never download or execute a file that doesn't have a virustotal scan attached."

So, if scan is attached, it's safe ?
What if scan is faked, or clean file is scanned and dirty file uploaded instead of scanned file?

Best prevention is to use brain and common sense.
