Its not TROJAN,
We are using ioncube as encryption for premium version of our plugin to protect source.
Some servers have no ioncube support and so we use some functions of php in nested way to protect sourcecode and providing nonioncube encoded files for them.
So we assure you, Its safe to our the files, its not trojan and some antivirus detecting it as trojan only because this kind of encryption is used by hackers to encrypt their files as its free to use and those files are not being supported by companies like ioncube for encryption.
We providing this self encrypted only for those who have no ioncube support on server.
Please scan the file on https://www.virustotal.com and you can see only NOD detecting it as virus.
Thanks for being with us.
