Can I send a file for deep analysis to somewhere ?

Hi !

I would like to know if a specific file is malicious. Ive already uploaded it to virustotal, and it was reported only by one AV, but Im not sure, since this is a software that should not use the network, and after it was reported by Bytehero as a downloader trojan, and i checked it and it was connected to the internet indeed.

Can i send this file somewhere to further analysis, so that i can be sure if its harmful or not ?
