It's a false positive.It's not a virus;your anti-virus just thinks it is because the beta's young.
Unless your anti-virus is terrible with configuration,it should have an option to leave the beta version alone.Heck,unless you go on some really shady sites,disabling for a short while (which your anti-virus should also allow it you to do) shouldn't give your computer anything terrible.If you don't know how to do either,then google it.
@jacksonmj Colouring the energy particle should probably affect the glow, in my opinion, as you are -technically- colouring the particle, after all...
