Double file encryption?

Question

Information Security

But if I encrypt the file 2 times with different algorithms, will it be more difficult for the antivirus to recognize it than if I encrypt the file 1 time?

Answer 1

the antivirus recognizes the virus by signatures, incl. after unpacking / decryption, which will somehow happen before its execution (I’m not sure how well modern antiviruses do this)
, so no, this will not increase the complexity of virus recognition at all,
and if it’s not a virus, then what does the antivirus have to do with it?
