Anti-virus Interrupts Installation

Issue

Your anti-virus software or firewall is blocking Metasploit from installing. 

Why

Metasploit is a software that tests whether a system is vulnerable to certain security issues. To do this, Metasploit exploits the same vulnerabilities as common malware and hacking software. This is what your anti-virus program detects and warns you about.

Fix

There are several fixes for anti-virus blocking: 

• Turn off your anti-virus program
• Exclude the Metasploit directory in your anti-virus software. Check your softwares instructions for steps on excluding a directory. 
• Disable your firewall
• Setup a virtual machine that does not have a firewall or anti-virus installed. The following are free open source options for virtualization: * Oracle VirtualBox - A open source virtualization software. https://www.virtualbox.org/
  • Ubuntu - An open source operating system https://ubuntu.com/download/desktop
