Can't build WebGL in Unity 5.3.5f1

Hi! I just make a empty scene with a sphere and a cilinder, camera and a point light. I try to build in webgl platform and Unity gets frozen in ‘stripping assemblies’. I wait some minutes and nothing. Then I kill the task in windows. I test it with Unity 5.3.5p2 and the same. What happens? Is it a bug???

This is what .log file tell:

Sorry, I just try it again and now It works. I don’t know what happened. Maybe something relative to my computer.

I was wrong. Tryed again and in stripping assemblies gets freezed.

I just find that desactivating antivirus Avast free, It works. I tryed two times and works. When I activate Avast Unity is freeze in stripping assemblies.
