Post Exploiting - How to Disable Anti Virus?

My friends and colleagues were successful with my computer and the firewall was open but I do not accept it because some modules like the Metasploitte persistence are virus-aware and meanwhile I do not have administrator authority on the system against the virus;

ACCESS DENIED when I try to close with CMD.

When I try to delete the Regeditte Run to prevent it from running at the beginning, ACCESS DENIED.

ACCESS DENIED when I try to delete system files in Program Files.

I took the mistake.

Is there any other solution to shutting down or try to miss modules like Metisploitte Persistence somehow from AV so how can I get away from AV? In the meantime, were the bumodules written in perl or ruby?

Sorry Guys Google Translate :)
