It's your choice in the end, I personally don't like disabling my anti for anything, I would recommend trying a different hack first. The main thing to watch out for with AV warnings is hacks that try to change system files or if it tries to open a suspicious .exe file, if you ever get those warnings close warrock straight away and delete the hack from your system before it does any damage..
It sounds like your AV warning was just from the hack trying to hook warrock.exe
