I'm trying make my file FUD with a crypter I bought here, but I test it at my old computer and file is deleted by windows defender.

What is a good scanner for runtime and scantime? Or should I test it myself in a virtual machine with the most common antivirus installed?

run4me.net
kleenscan.com
CyberScan.org

You can also scan at antiscan.me (not sure about Runtime tho?)

Also the crypter you got probably uses a shared stub and is currently not FUD.

When you scan/run your file on your system, also make sure to disable sample submission in your AVs first or it might distribute samples

I think it is FUD... only 1 detection at cyberscan.org and 4 detections at kleescan.org.
I did not test with run4me.net because is necessary to pay. Cyberscan.org has 1 free scan/day and kleenscan.org is free for registered users.
But windows defender deletes the file when I click on it. Probably Cyberscan.org and Kleenscan.org only scan for scantime, not runtime.

I'm not sure if you understand what FUD means.... it means Fully Undetectable, which means 0/32 results 0% detection everywhere.
1/32 can be considered just UD already, not to mention 4+ detections.

If Windows Defender detected your file, it is definitelly not FUD, more like UD and detected by specific AVs.
Also, WD is considered a pretty crappy AV. If WD detects it, I can't even imagine how easily ESET / Avira / Bitdefender / Kaspersky / Avast / AVG is gonna detect it aswell.

Thanks! Now I understand better what FUD means. 90% FUD is not FUD, specially if detected by windows defender.
