I use Vega X Executor as well and it's really cool. Disabling antivirus was a bit scary at first, but then I got used to it, because most script executors require the same. It works surprisingly stable, and the interface is nice. I'm especially glad that you don't need to mess with keys, as it happens with other free executors. So if you are looking for something simple and reliable, Vega X is definitely a worthy option!
