Evading AV QuestioN

Hello guys Sodacni Here,

In a VM enviromnent I sucessfly bypassed AV with a c sharp exe in windows 8.1 x64 with veil-evasion, got a session, but the problem was when i wanted to make the backdoor persistent, i run the persistence msfconsole command says that installed everything ok, but in reality AV blocked some VBS files in the process, so on reboot i dont get a new connection. any ideas?
