Help with Enigma

Hello sir's, im newbie with the hacks, so i have a question.

I am trying protect some hacks with the Enigma Demo,but when i finish the protect my antivirus detect a virus, then it is not easier for the vac detect the hack?

It's normal?

I should stop using the Demo of Enigma and try a cracked version?

Someone have the cracked version to pass?

There is anyother better than the standard configuration to protect?

Vm protect is better than enigma?

.And sorry for my english i'am Brazilian.

Most hackers uses Enigma ,i think its the same, dont use a cracked version because its probably not up to date,just use the demo is enough http://enigmaprotector.com/en/downloads.html
